Hillman Fasteners 270006 1/4 Inch Flat Washer Zinc Steel 5 Lb

Product Description

The HILLMAN FASTENERS 270006 is a bulk-pack flat washer designed for high-volume fastening work in construction, mechanical, and trade applications. Each pack contains approximately 745 zinc plated steel washers in a 1/4 inch size, conforming to the USS wide pattern standard. The wide pattern profile distributes load across a larger bearing surface than standard flat washers, reducing the risk of pull-through on softer substrates. Zinc plating provides corrosion resistance for general-purpose indoor and outdoor use. The 5-pound pack format suits contractors and service pros who stock hardware in bulk.

These washers are suited for residential and light commercial construction, mechanical assemblies, HVAC equipment mounting, plumbing support hardware, and electrical panel or conduit work. The USS wide pattern designation makes them a common choice when bearing surface area matters, such as when fastening into wood framing, sheet goods, or sheet metal with clearance holes. Each carton contains 12 individual 5-pound packs, supporting stocking at the supply house or job-site trailer level.

Installation Notes

Flat washers are installed by plumbers, electricians, HVAC technicians, and general contractors as part of standard fastening assemblies. Always match the washer inner diameter to the fastener shank size and verify the wide pattern outer diameter clears any countersink or recessed seat. Zinc plated washers are not recommended for continuous immersion or highly corrosive environments where stainless or hot-dip galvanized hardware may be required. No special tools are required for installation beyond standard hand or power fastening equipment.
