Fender Washer 1/4 in x 1-1/4 in zinc-plated steel FENWZ14125
Zinc-plated steel fender washer sized for 1/4 in fasteners with a 1-1/4 in outside diameter. Commonly used to spread load over a larger surface area, cover oversized holes, and reduce pull-through on sheet metal, enclosures, and panel work.
What this product is for
This zinc-plated steel fender washer is used with 1/4 in bolts, screws, or threaded rod where a larger bearing surface is needed. The wide outside diameter helps distribute clamping force across thin material, sheet metal, plastic, or oversized holes.
Use for
Use for electrical enclosures, panel hardware, strut accessories, sheet metal fastening, sign mounting, and general repair work. It is commonly selected when a standard flat washer does not provide enough surface coverage.
Avoid for
Avoid for highly corrosive environments, washdown areas, or exterior coastal locations where stainless steel hardware is typically a better choice. Do not use as a locking washer where vibration resistance is required.
Best for
Best for contractors and electricians who need a simple way to reduce pull-through and support thin materials during fastening. Typical trade use is under the head of a bolt or under a nut to spread the load over a wider area.
Installed in
Installed in indoor electrical rooms, commercial fit-outs, service spaces, maintenance work, and light exterior applications where zinc-plated steel is acceptable.
Why this product exists
Fender washers are made with a relatively small inside diameter and a larger outside diameter so the fastener load is spread across more surface area. This helps protect softer materials and can help bridge oversized or irregular holes.
Compared with similar products
Compared with a standard flat washer, a fender washer provides more coverage and better load distribution. Compared with stainless steel versions, zinc-plated steel is typically more economical for dry or lightly exposed locations. Actual corrosion performance depends on installation conditions and environment.
