Choosing a surface anchor retainer comes down to matching the plate to your mounting surface and deciding whether you need one anchor or several. I rank the Keyfit Tools Low Profile Anchor Plate (4 Pack) as my best overall pick for securing tie-down points around a property, while the 1 Pack is the more focused choice for a single bike-lock or strap location. Both use a powder-coated steel plate and folding U-ring, and neither includes screws or concrete anchors.

The main tradeoff is not a major difference in function: it is quantity versus footprint. The four-pack has a stated 3 x 3-inch plate, while the single plate is listed at 2.5 x 2.5 x 0.37 inches. I would choose based on the number of anchor points I need and the space available, then select fasteners suited to the surface. These are surface-mounted retainers for hard surfaces, not overhead anchors or stand-alone fastening systems.

Key Takeaways
- I rank the 4 Pack first for buyers who want multiple tie-down points across a garage, deck, patio, or driveway.
- The 1 Pack suits a single planned location and has the smaller stated plate dimensions: 2.5 x 2.5 inches.
- Both models use a folding U-ring and powder-coated alloy steel; neither listing includes mounting screws or anchor bolts.
- The listed 5/16-inch fastener compatibility does not replace checking the plate, fastener, substrate, and load requirements together.
- Neither option is intended for overhead anchoring, and both depend on installation into a suitable hard surface.

Keyfit Tools Low Profile Anchor Plate (4 Pack) for Concrete, Decks, and Hard Surfaces
I give the four-pack the lead because surface anchoring projects often call for more than one fixed point. Four plates can serve several tie-down positions or let a buyer place matching retainers in different parts of a garage, deck, or patio. Compared with the single-plate option, this package offers more planning flexibility without changing the basic installation approach: each plate still needs its own suitable fasteners, which are not supplied.
The listed plate size is 3 x 3 x 1 inches, and the design pairs powder-coated alloy steel with a folding U-ring. The low-profile, foldable ring is intended to sit down when not in use, a practical detail around walking or storage areas. Its finish is also described as paintable, which may help the plates blend into a chosen surface, although the product information does not specify a paint system or preparation method. The U-ring provides a connection point for compatible tie-downs, ratchet straps, or bike locks; buyers still need to match the rest of their setup to the load and application.
The four-pack is not automatically the right answer for every installation. Its stated footprint is larger than the 1 Pack’s, so the single plate may suit a confined mounting spot better. More importantly, a multi-pack does not include the screws or concrete anchors required to secure it. I would plan the fasteners around whether the base is concrete, wood, or asphalt rather than treating the listed 5/16-inch compatibility as a complete installation prescription. This model is a strong choice for several ground-level anchor points, but not for overhead restraint or any use where the surface and fixing method have not been checked.
Pros:- Four plates support multi-point layouts without buying separate single units.
- Powder-coated alloy steel offers a durable, paintable surface.
- The folding U-ring keeps the retainer lower when it is not in use.
- Listed for use on concrete, wood decks, patios, and asphalt driveways.
Cons:- Screws and concrete anchors are not included, so installation hardware must be selected separately.
- The stated 3 x 3-inch footprint may be less suitable for a cramped mounting area than the 1 Pack.
- Not suitable for overhead anchoring or soft, unsuitable mounting surfaces.
Best for: Buyers planning several ground-level tie-down, strap, or bike-lock points across a garage, deck, patio, or driveway.
Not ideal for: Anyone who needs only one plate, has very limited mounting space, expects included fasteners, or needs an overhead anchor.
- Material:Alloy steel
- Finish:Powder coated
- Plate dimensions:3 x 3 x 1 inches
- Package quantity:4 plates
- Weight:16 ounces (listed)
- Thread / fastener size:5/16 inch
- Compatible groove diameter:0.31 inches
- Mounting hardware:Screws or concrete anchors not included
Our verdict“I recommend the four-pack when I need several low-profile anchor points and can source fasteners suited to each mounting surface.”
Keyfit Tools Low Profile Anchor Plate (1 Pack)
For a single locking or tie-down position, I would choose the 1 Pack rather than buy four plates I may not use. It has the same core idea as my top pick: a powder-coated steel plate with a folding U-ring and four mounting holes. That shared design means the choice is mainly about quantity and listed footprint, not a different anchoring method. Its stated dimensions are 2.5 x 2.5 x 0.37 inches, making it the smaller listed plate compared with the four-pack model’s 3 x 3 x 1-inch dimensions.
This version is described for tie-downs, bike locks, and hurricane anchoring on concrete, wood, or asphalt. The four-hole layout gives the installer multiple mounting points on the plate, but it does not remove the need to choose appropriate screws or anchor bolts. Those are not included. The listing says compatible screw diameter is up to 5/16 inch; I would treat that as a compatibility limit to verify against the plate and surface, not as a guarantee that a particular fastener will suit every installation.
Compared with the four-pack, this is easier to match to a one-point job or tighter mounting area, but it offers no spare plate if I later want to add another location. The product information also does not provide a load rating, so I would not infer a safe working load from the steel construction or hole count alone. Buyers should check their intended use, substrate, fasteners, and any applicable load guidance before relying on the anchor. It shares the same key exclusions as the four-pack: no supplied mounting hardware and no overhead use.
Pros:- Single-plate quantity suits a one-location installation.
- Smaller stated footprint than the four-pack model’s plate dimensions.
- Powder-coated alloy steel construction with a folding U-ring.
- Four-hole mounting layout and compatibility with screws up to 5/16 inch, subject to surface and fastener fit.
Cons:- Only one plate is supplied, so multiple positions require additional units.
- Mounting screws and anchor bolts are not included.
- Not suitable for overhead anchoring, and no load rating is stated in the supplied details.
Best for: Someone securing one ground-level bike-lock, tie-down, or strap location, especially where the smaller listed footprint is useful.
Not ideal for: Buyers setting up several anchor points, those who need supplied screws or anchor bolts, or anyone seeking overhead anchoring.
- Material:Alloy steel
- Finish:Powder coated
- Color:Red
- Item dimensions:2.5 x 2.5 x 0.37 inches
- Package quantity:1 plate
- Compatible screw diameter:Up to 5/16 inch
- Thread size:5/16 inch
- Mounting layout:Four-hole plate with folding U-ring
- Mounting hardware:Screws and anchor bolts not included
Our verdict“I would pick the single plate for one planned anchor point or a tighter mounting area, but not for a project that needs several retainers.”
How We Picked
I compared these products as surface anchor retainers, rather than treating them as generic hardware. My ranking focuses on the choice a buyer actually faces: how many anchor points are needed, how much mounting area is available, and what must be arranged separately before installation. Both products share a low-profile plate-and-folding-ring design, so I do not present either as a different class of anchor or claim a tested load capacity that the supplied details do not provide.
The four-pack ranks first because it offers four matching plates for projects that call for several tie-down or locking locations. The single plate ranks second, not because it is inherently weaker, but because it covers only one mounting point and is therefore less flexible for a multi-point setup. Its smaller stated dimensions can be useful where space is tight. I also weighed the practical limits common to both: fasteners are not included, installation depends on the mounting surface, and neither model is suitable for overhead use. I based these distinctions on the product details provided, not on hands-on testing.

Factors to Consider When Choosing Surface Anchor Retainers
I would decide between these retainers by starting with the number of anchor points, then checking the plate footprint, mounting surface, and fasteners. Both products share a similar low-profile folding-ring design, so the practical fit of the installation matters more than choosing between two different mechanisms.
Choose quantity before comparing small design differences
The clearest distinction is four plates versus one. I would select the four-pack if I want several fixed points for straps, locks, or securing equipment in more than one position. It can suit a layout where repeated anchor locations matter, though each plate still needs separate mounting hardware. The single pack makes more sense for one defined job: a bike-lock point by a door, one tie-down position, or a replacement for an existing retainer. If a second location is likely soon, the four-pack may reduce the need to source another plate later.
Quantity is not a measure of strength. The supplied product information does not give a load rating for either model, so I would not infer that four plates make a particular load safe or that one plate has a known capacity. Match each anchor to the intended load and installation requirements.
Match the plate and fasteners to the surface
These are surface-mounted products intended for concrete, wood, or asphalt, depending on the listing. Those materials do not all take the same fastener. Concrete generally calls for a suitable concrete anchor, while wood requires a fastener appropriate to the timber and installation. The product descriptions say screws or anchors are not included; the 4 Pack also describes its design as compatible with various screws or anchors. I would confirm the fastener’s diameter and fit with the plate, then check that it is appropriate for the specific substrate and application.
Do not treat the shared 5/16-inch information as a complete instruction for installation. The 4 Pack lists a 5/16-inch thread or fastener size, while the 1 Pack lists compatible screws up to 5/16 inch. Those details help narrow compatibility, but they do not identify a specific anchor, embedment depth, or safe load for every surface.
Compare footprints and everyday clearance
The 1 Pack’s stated dimensions are 2.5 x 2.5 x 0.37 inches, while the four-pack listing gives 3 x 3 x 1 inches. If the mounting area is tight, I would measure the available space and compare it with the plate, ring movement, and chosen fastener heads before buying. The folding U-ring is intended to lower when unused, which may help keep the retainer less obtrusive than a permanently upright loop. It does not make the plate flush or remove the need to place it where feet, wheels, and stored items will not catch on it.
Because the supplied dimensions are presented differently, I would verify the seller’s current product measurements if a very precise fit is required. The practical distinction remains useful: the single plate is the smaller stated option, while the four-pack provides more anchor positions.
Keep the use ground-level and task-specific
Both listings rule out overhead anchoring. I would keep either retainer to suitable ground-level applications such as a tie-down, ratchet strap, or bike-lock point, and avoid using it where failure could put a person at risk. The product descriptions do not state a load capacity, so the steel material and plate design alone cannot establish a safe working limit. For demanding or safety-critical uses, seek product-specific load information and follow the applicable installation guidance rather than guessing.
Paintability may help the four-pack blend into a setting, and the single plate is listed in red. Neither finish changes the need to inspect the mounting surface and hardware. A plate only works as part of the whole assembly: retainer, fasteners, base material, and the item being secured all matter.
Frequently Asked Questions
What is the main difference between the Keyfit Tools 4 Pack and 1 Pack?
The most direct difference is quantity: one listing supplies four plates and the other supplies one. The 1 Pack also has smaller stated dimensions of 2.5 x 2.5 x 0.37 inches, compared with the four-pack model’s listed 3 x 3 x 1 inches. Both use a powder-coated steel plate and folding U-ring, and neither includes mounting screws or concrete anchors.
Do either of these surface anchor retainers include mounting hardware?
No. The product details say screws, anchor bolts, or concrete anchors are not included. I would choose fasteners for the actual mounting surface and verify that their size and type fit both the plate and the installation. The stated 5/16-inch compatibility information is not a substitute for checking the complete setup.
Can I install these plates on concrete, wood, or asphalt?
The listings describe use on concrete, wood, and asphalt surfaces, but each base material may call for different mounting hardware and installation steps. I would not use the same fastener by default across all three. Check the retainer’s fit, the fastener maker’s guidance, and the condition of the surface before installation.
Are these suitable for overhead anchoring or do they have a stated load rating?
Neither listing is suitable for overhead anchoring, and the supplied details do not state a load rating. I would not estimate capacity from the material, number of holes, or package quantity. For any application where a failure could cause injury or property damage, use a product with clear load guidance and installation instructions appropriate to the task.
Which model should I choose for a bike lock or tie-down?
I would choose the 1 Pack for one planned bike-lock or tie-down location, especially if its smaller stated footprint fits the available area. The 4 Pack is the better match when I need several anchor points around a garage, deck, patio, or driveway. In either case, the fasteners and mounting surface need to suit the intended use.
Conclusion
For a project that needs multiple surface anchor points, I recommend the Keyfit Tools 4 Pack: it provides four matching folding-ring plates and gives me more placement options. For a single bike-lock or tie-down point, or where a smaller stated plate footprint matters, I would choose the 1 Pack instead. Before either purchase, I would confirm that the mounting surface is suitable, source the correct fasteners separately, and keep the application ground-level. Neither product is the right choice for overhead anchoring, and the supplied details do not establish a load rating.
