Value Collection 742136PS M16 Internal Tooth Lock Washer

Product Description

The VALUE COLLECTION 742136PS is a Grade 2 spring steel internal tooth lock washer designed for use with M16 fasteners. It features an inside diameter of 17.0mm, an outside diameter of 26.0mm, and a thickness of 1.2mm. The zinc-plated finish provides basic corrosion resistance for general-purpose applications. Internal teeth bite into both the fastener bearing surface and the mating material to resist loosening caused by vibration or dynamic loading. This washer is installed by electricians, plumbers, HVAC technicians, and general mechanical trades wherever a secure M16 fastener connection is required.

This internal tooth lock washer is suited for residential and light commercial applications where M16 screws or bolts are used in assemblies subject to vibration or repeated stress cycles. Common install scenarios include equipment panels, brackets, mechanical mounts, and general fastening applications across HVAC, plumbing, and electrical work. It does not meet military specifications and is intended for standard commercial service.

Installation Notes

Install this lock washer between the fastener head or nut and the mating surface before final torque is applied. Ensure the tooth side faces the fastener bearing surface for proper engagement. Power down or de-energize any equipment before working on fastened assemblies in electrical or HVAC panels. Follow applicable NEC or mechanical codes for the specific installation context.
