Flat Washer · 1/4 in zinc-plated steel · load-distributing washer · Fitsfast 170020

SKU: FIT-170020

1/4 in zinc-plated steel flat washer for use with standard 1/4 in bolts, screws, and nuts in electrical, construction, and general fastening work. Commonly used to spread load under the fastener head or nut and help reduce pull-through on slotted or oversized holes.

What this product is for

This 1/4 in flat washer is used under a bolt head or nut to spread clamping force across a wider surface. It is commonly selected for panel work, strut assemblies, equipment mounting, and general fastening where a plain bearing surface is needed.

Use for

Use for 1/4 in threaded fasteners in indoor electrical and construction applications, and in light exposed locations where zinc-plated steel is acceptable. It is suitable where you need basic corrosion resistance and better load distribution than a bare fastener head alone.

Avoid for

Avoid for highly corrosive environments, washdown areas, marine locations, or assemblies requiring stainless hardware throughout. Avoid using a standard flat washer as a locking device where vibration resistance is the main requirement.

Best for

Best for electricians and contractors stocking common 1/4 in hardware for enclosures, brackets, channel, supports, and general service work. A flat washer is a practical choice when you need to protect the mounting surface and improve bearing area.

Installed in

Typically installed in panels, cabinets, junction box supports, strut-mounted accessories, mechanical brackets, and general equipment fastening points. For size reference, 1/4 in is approximately 6.4 mm.

Why this product exists

Flat washers help distribute force, reduce surface marking, and support more even tightening on softer or painted materials. In trade use, they are commonly added where the fastener head or nut would otherwise bear on a small area.

Compared with similar products

Compared with a lock washer, this product is intended for load distribution rather than vibration resistance. Compared with stainless steel washers, zinc-plated steel is typically a lower-cost choice for general indoor use but offers less corrosion resistance in aggressive environments.
