Metallics W113B Washer 1/4 x 1 Fender Wshr St-Zn(1pc)

The W113B is a 1/4 inch fender washer, so it goes over 1/4 inch bolts, screws, or threaded rod. The washer itself is 1 inch across, which gives you a much larger bearing surface than a standard 1/4 inch flat washer.

Use a fender washer like the 1/4 x 1 W113B when the hole is oversized, the material is thin or soft, or the load needs spreading, sheet metal, drywall, panel work, strut and box mounting. The 1 inch outside diameter on a 1/4 inch bolt spreads clamping force over a wide area so the fastener head does not pull through. A standard 1/4 inch flat washer has a much smaller OD and is the right choice when you just need a bearing surface under a nut on solid material.

It is zinc plated steel, which handles indoor and normally dry or occasionally damp locations well. For continuous exposure, wet locations, or corrosive environments, step up to a stainless steel fender washer instead, zinc plating will eventually sacrifice and rust through.

It is sold as one piece, a single 1/4 x 1 zinc plated steel fender washer. If you are doing a full run of panel or strut work, order the piece count you need rather than expecting a bulk box.

Yes. That is the common use for the W113B. On drywall, thin sheet metal, or a punched panel where the hole is larger than the 1/4 inch fastener, the 1 inch outside diameter bridges the opening and keeps the bolt head or nut from pulling through. For heavier structural anchoring into concrete or steel, use a hardened structural washer instead, a plated fender washer is not a load-bearing structural part.
