Value Collection 81923864 7/16 in Split Lock Washer 25pk

Product Description

The VALUE COLLECTION 81923864 is a Grade 2 steel split lock washer sized for 7/16 inch screws and fasteners. The zinc plated finish provides basic corrosion resistance for general-purpose indoor and light outdoor applications. With an inside diameter ranging from 0.44 to 0.45 inches and an outside diameter ranging from 0.683 to 0.776 inches, this washer seats securely under bolt heads and nuts to resist loosening from vibration and torque. Thickness measures 0.109 inches nominal. Sold in a pack of 25, this washer suits high-volume assembly work and service calls where consistent fastener retention is required.

Split lock washers of this size are used across HVAC, plumbing, electrical, and general mechanical assembly where fasteners must resist backing out under vibration or thermal cycling. Typical applications include equipment panel fastening, conduit bracket mounting, ductwork hardware, and mechanical equipment frames. Grade 2 steel construction covers the majority of standard-duty fastening requirements encountered in residential and light commercial trade work.

Installation Notes

Split lock washers are installed by placing the washer on the fastener shank between the nut or bolt head and the mating surface before tightening. Power down or de-energize any equipment before servicing fastened assemblies on electrical or HVAC components. Ensure the fastener diameter matches the washer ID range for proper seating. Do not reuse compressed or deformed lock washers, as they will not provide effective retention once the helical spring action is lost.
