Hillman Fasteners 290003 Fender Washer No. 10 X 1 in 100 Pack

Product Description

The HILLMAN FASTENERS 290003 is a zinc plated steel fender washer sold in a 100-piece pack. Fender washers feature a larger outer diameter relative to the center hole, distributing load over a wider surface area to prevent pull-through and reduce surface damage. The zinc plating provides corrosion resistance for general indoor and light outdoor use. Each washer fits a No. 10 bolt with a 1 inch outer diameter. This fastener is a standard consumable used by electricians, plumbers, HVAC technicians, carpenters, and general contractors across a wide range of trade applications.

Fender washers in this size are commonly used in residential and light commercial construction and service work. Typical applications include securing electrical junction box covers, attaching sheet metal panels, anchoring conduit straps, and reinforcing connections in wood framing. The larger bearing surface makes them especially useful wherever standard washers would allow a fastener head or nut to pull through thinner or softer materials. The 100-piece pack suits service van stocking and small project use.

Installation Notes

Fender washers are installed by general contractors, electricians, plumbers, and HVAC technicians using standard hand or power tools. Always select a washer whose inner diameter matches the fastener shank and whose outer diameter suits the bearing surface required. Do not use zinc plated washers in highly corrosive or submerged environments where stainless or hot-dip galvanized hardware is specified. Verify fastener torque requirements per the applicable code or equipment manufacturer guidance before final assembly.
