Value Collection 99727 3/4 in Grade 8 Steel Split Lock Washer

Product Description

The VALUE COLLECTION 99727 is a Grade 8 steel split lock washer designed for 3/4 inch fastener applications. Split lock washers apply tension under a fastener head or nut to resist loosening caused by vibration and torque relaxation. This washer ships uncoated with a bright finish and is manufactured to inch-system dimensional standards. It is used across mechanical, structural, and utility installations where high-strength fastener assemblies are required. The 0.188 inch thickness and Grade 8 material rating make it appropriate for demanding bolted joint applications in industrial, HVAC equipment mounting, and general trade work.

This split lock washer suits residential and commercial installations wherever 3/4 inch bolts or screws require vibration resistance. Common applications include equipment base mounting, structural steel connections, and mechanical assemblies subject to dynamic loads. Tradespeople including HVAC technicians, pipefitters, electricians, and millwrights use this type of washer when assembling or securing heavy equipment components. The bright uncoated finish is suited for indoor or protected environments where corrosion exposure is limited.

Installation Notes

A licensed mechanic, electrician, or qualified tradesperson should verify fastener grade compatibility before assembly. Power down or de-energize any equipment before accessing fastener locations on live systems. Place the washer between the fastener head or nut and the mating surface with the split gap oriented to bite into both surfaces as the fastener is tightened. Do not reuse split lock washers that have been fully compressed flat, as they will not provide effective locking action.
