The VALUE COLLECTION KP1937-1 is a USS flat washer made from steel with a zinc-plated finish, sold in a pack of 250. USS flat washers feature a larger outer diameter relative to the bolt size compared to SAE washers, providing a wider bearing surface that distributes load more effectively across the fastened material. This washer measures 3/16 inches inner diameter, 7/16 inches outer diameter, and 0.04 inches thick. The zinc plating provides baseline corrosion resistance suitable for general interior and light-duty exterior applications. Plumbers, electricians, HVAC technicians, and general contractors use these washers daily in mechanical assemblies, equipment mounting, and structural fastening tasks.
This washer is appropriate for use with 3/16-inch fasteners in residential and light commercial construction, mechanical rooms, equipment installations, and utility assemblies. The USS designation makes it a common choice when a broader load-distribution surface is required, such as when fastening into softer substrates or oversized clearance holes. The 250-piece pack quantity suits service vans, job-site bins, and shop stock for ongoing maintenance and installation work.
Designed for use with 3/16-inch bolts, screws, and threaded fasteners in standard inch-measurement assemblies across general mechanical, plumbing, electrical, and HVAC installation applications.
Install these washers with the appropriate 3/16-inch fastener using standard hand or power tools. Always de-energize electrical systems or shut off fluid supply before disassembling any fastened joint in live service equipment. Do not use zinc-plated washers in direct contact with pressure-treated lumber or in continuously submerged environments where a higher corrosion-resistance rating is required. Follow applicable mechanical and building codes for fastener bearing-area requirements.
