Value Collection 31516 Wedge Lock Washer 1/2 in Steel Grade 2

Product Description

The VALUE COLLECTION 31516 is a zinc-plated wedge lock washer designed to maintain clamp load and resist loosening under vibration and dynamic loading. Made from Grade 2 steel with a zinc flake finish, this washer measures 0.778 inches in outside diameter and accepts a 1/2 inch thread size, with an inside diameter ranging from 0.522 to 0.538 inches. The minimum outside diameter is 0.762 inches. It is installed by mechanical contractors, maintenance technicians, and industrial assemblers wherever fastener joint integrity is critical. Each package contains 100 washers.

Wedge lock washers are used in structural, mechanical, and industrial bolted connections subject to vibration, thermal cycling, or dynamic loads. They are suited for both residential and commercial applications including equipment mounting, structural steel connections, machinery assembly, and general mechanical fastening. The zinc-plated zinc flake finish provides corrosion resistance for indoor and moderately exposed outdoor environments. This washer conforms to ISO 14001 and ISO 9001 standards, making it appropriate for quality-controlled manufacturing and maintenance operations.
