Shelf Supports: Three Listings Compared by Stated Specs
The person typing shelf supports wants to hold a shelf up safely, so the question is which support fits the shelf, the wall or cabinet, and how much weight it takes. This guide compares three non-sponsored results from an Amazon search read on 2026-10-28. It uses only figures the listings state. Where a listing does not give a figure, the table says “not stated,” and where the three products are different types, that is shown.
Quick answer
- For a wall shelf that needs a stated load, the Amazon Basics bracket pair lists 1,000 lbs per pair when mounted into 16-inch wall stud centers. That figure assumes studs.
- For a floating look with a stated load per pair, the Starunder brackets list up to 150 lbs per pair. The listing does not say what mounting that figure assumes.
- For a cabinet or bookcase with drilled holes, a shelf pin kit is the right type, and the listing gives its hole sizes but no load.
- Whichever type you buy, confirm the wall or cabinet material before you drill, and use a stud or a rated anchor.
Comparison table
The table uses only the columns the listings state. “Not stated” means the listing does not give that figure.
| Product (ASIN) | Type (listing) | Size (listing) | Load (listing) | Mounting (listing) | Hardware included (listing) |
|---|---|---|---|---|---|
| Amazon Basics 10 Pack Metal Shelf Brackets (B07PJTYNC7) | Wall bracket, Q195 steel | 20 in x 13 in | 1,000 lbs per pair into 16-inch stud centers | Pre-drilled 1/4 inch holes, 3 per side | Not included |
| 104 Pc Shelf Pins Kit (B094NPL7TW) | Shelf pin and peg, nickel-plated zinc alloy | 5 mm to 6.35 mm x 7.5 mm to 25 mm | Not stated | Drilled hole, 5 mm and 1/4 inch | Pins are the kit |

The three products, one by one
Amazon Basics 10 Pack Heavy Duty Metal Shelf Brackets (B07PJTYNC7)
This is a set of ten black steel brackets, 20 inches long by 13 inches high. The listing gives the most detailed load figure of the three, and the figure is tied to a stud spacing.
The listing says:
- Bracket dimensions: 20 inches by 13 inches. Item dimensions: 20 x 1.18 x 13 inches.
- Material: alloy steel, made from Q195 steel with a black powder coated finish.
- Item weight: 1.49 pounds. Model number: AB5502.
- Mounting: “Mounting hardware not included.” The bracket has 3 pre-drilled 1/4 inch holes on each side.
- Load: “1,000 lbs. (453.6 kgs) max weight capacity per pair when mounted into 16-inch wall stud centers.”
Skip if: you cannot find studs at the spacing the listing names. Also skip it if you need hardware in the box, because the listing says mounting hardware is not included.
Limitation: the listing gives the figure for a pair into studs at 16-inch centers. It does not give a figure for drywall, plaster or masonry, and it does not say whether the figure applies to a single bracket.
104 Piece Shelf Pins Kit, 4 Styles (B094NPL7TW)
This is a kit of nickel-plated pegs and pins for drilled shelf holes in a cabinet, bookshelf or closet. It is a different type from the two brackets, because it sits in holes rather than on a wall.
The listing says:
- Material: zinc alloy with a polished nickel finish. Pin type: dowel.
- Size: 5 mm to 6.35 mm (1/4 inch) in diameter, and 7.5 mm to 25 mm in length.
- Kit: 104 pieces in 4 styles, including 8 L-shaped support pins with hole and 10 dowel pins.
- Fit: “Shelf support pegs can fits all cabinets with 5mm and 1/4 Inch holes.”
- Installation: installs by hand. The listing says the hole should be equal to or slightly smaller than the pin diameter for a tight fit.
Skip if: you need to carry weight on the wall, because the pins sit in holes in a cabinet or bookcase and the listing gives no load.
Limitation: the listing does not state a load for the pins. The brand was not captured.
Starunder 6 Inch Floating Shelf Brackets, 6 Pack (B09DSZ3LFW)
This is a six-pack of black iron L-shaped brackets with a concealed design, sized for a floating shelf. The listing describes it for living room, bedroom, kitchen, bathroom, garage and office shelves.
The listing says:
- Material: heavy-duty iron with a thick black matte coating. Color: black.
- Load: “each pair of shelf bracket supports up to 150 lbs.”
- Design: concealed, with no visible hardware, and installed upward or downward.
- Thickness: one-fifth inch, per the title.
Skip if: you need the screws or anchors in the box, because the listing does not describe them. Also skip it if you need a load figure tied to a stud spacing, since the listing does not give one.
Limitation: the listing gives 150 lbs per pair, and does not say what wall type or stud arrangement that figure assumes. The spec table was not fully captured.
How we chose
We read three non-sponsored results from an Amazon search for “shelf supports” on 2026-10-28. Sponsored results were skipped. The three were chosen to show three different types the search returns: a wall bracket with a stated stud-based load, a pin kit for drilled holes, and a concealed floating bracket with a stated pair load. The choice reflects the listing data, not a ranking, and we did not rank by price, rating or sales.
What we could not verify
- Whether any bracket carries its stated load in drywall, plaster or masonry. The listings do not state these conditions.
- Whether the Starunder 150 lb figure applies to studs, anchors or a single bracket. The listing does not say.
- Whether the pins hold weight over time. The listing gives no load and the sources we opened do not cover pin loads.
- The brand of the pin kit, which was not captured.
Wall mounting and anchoring
Brackets carry a shelf’s weight into the wall, so where they are fixed matters as much as the stated number. The University of Oregon shelving safety sheet says: “Anchor shelves to the floor or wall to prevent the unit from falling over in an earthquake.” The same sheet says: “Do not overload shelves and make sure items aren’t hanging over the edge.”
In practice, find a stud if you can and use the stud spacing the listing names. If you cannot, use a rated anchor for your wall type, and follow the anchor’s own load rating rather than the bracket’s figure. Keep items off the front edge of the shelf, and do not load a shelf beyond what its bracket and its fixing can carry. The listings do not describe the anchors that suit each wall type, so check the hardware notes before drilling.
Buying checklist
- Decide what the support does: carry a shelf from the wall, sit in a cabinet hole, or hold a floating shelf.
- Find the stud spacing in your wall, and compare it with the 16-inch figure in the Amazon Basics listing.
- Check whether the brackets include screws. The Amazon Basics listing says they do not.
- For a pin kit, measure the hole diameter. The listing says 5 mm and 1/4 inch.
- For a floating bracket, check the stated load per pair, and confirm the wall type before you buy anchors.
Mistakes to avoid
- Treating a pair figure as a single bracket figure. The Amazon Basics figure is for a pair. The Starunder figure is for a pair.
- Assuming studs when there are none. The Amazon Basics figure is tied to 16-inch stud centers.
- Using pins for a wall load. The pin kit is for drilled holes, and the listing gives no load.
- Drilling a hole that is too big. The pin listing says a snug fit needs a hole equal to or slightly smaller than the pin.
- Overloading the shelf. The University of Oregon sheet advises against overloading shelves.
Frequently asked questions
What weight can a shelf support hold?
The Amazon Basics listing gives 1,000 lbs per pair when mounted into 16-inch wall stud centers. The Starunder listing gives up to 150 lbs per pair. The pin kit listing does not state a load.
What is the difference between a shelf support bracket and a shelf pin?
A bracket is fixed to the wall and carries the shelf. A shelf pin is a small peg that sits in a drilled hole inside a cabinet or bookcase. The Amazon Basics and Starunder products are brackets, and the 104 piece kit is pins.
Do I need to hit a stud for a shelf bracket?
The Amazon Basics figure assumes studs at 16-inch centers. The listing does not give a figure for other mounting. The University of Oregon sheet says to anchor shelves to the floor or wall. Use a stud or a rated anchor, and do not assume a load for a generic anchor.
Do shelf pins need a specific hole size?
The pin kit listing says it fits cabinets with 5 mm and 1/4 inch holes, and that a tight fit needs a hole equal to or slightly smaller than the pin diameter.
Can a floating shelf bracket go upward or downward?
The Starunder listing says its brackets can be installed upward or downward. It does not describe the screws or anchors that come with them.

Bottom line
Match the support to the job. A wall bracket needs a stated load and a fixing you can trust. The Amazon Basics pair gives the most detailed figure, but only into 16-inch stud centers. The Starunder pair gives 150 lbs per pair with no stated fixing. A pin kit is for drilled holes, not walls. Find your stud spacing and wall type first, then choose the support whose listing matches them.
