Value Collection FWSIS0-30-10LBBX Sae Flat Washer

Product Description

The VALUE COLLECTION FWSIS0-30-10LBBX is a Number 3 screw size SAE flat washer made from steel with a zinc-plated finish. It meets ASME B18.21.1 standards for dimensional consistency and is suited for use in fastener assemblies where load distribution and corrosion resistance are required. The washer measures 7/64 inches inner diameter, 1/4 inch outer diameter, and 0.035 inches thick. Material grade 2 steel provides adequate tensile strength for light-duty and general mechanical applications. Plumbers, electricians, HVAC technicians, and general tradespeople use this type of washer in equipment assemblies, panel work, and fixture mounting.

This SAE flat washer is appropriate for residential and light commercial applications wherever a Number 3 screw fastener requires a bearing surface to distribute clamping load and protect the mating surface. Common installation scenarios include securing junction box covers, equipment panels, light fixtures, and plumbing or HVAC mounting brackets. The zinc plating adds a baseline level of corrosion resistance suitable for indoor and dry to moderately humid environments.
