Value Collection 31328 Split Lock Washer 7/16 in Grade 5

Product Description

The VALUE COLLECTION 31328 is a Grade 5 steel split lock washer designed for 7/16 inch screw applications. It features a zinc-plated finish that provides basic corrosion resistance in standard service environments. The washer measures 0.44 to 0.45 inches minimum inside diameter, 0.776 inches maximum outside diameter, and 0.109 inches thick. Split lock washers are installed under fastener heads or nuts to resist loosening caused by vibration and torque relaxation. This part is a standard inch-series fastener component used across mechanical, structural, and equipment assembly work by electricians, HVAC technicians, plumbers, and general tradespeople.

This split lock washer is suited for general-purpose fastening in residential and light commercial applications. It is commonly used when assembling mechanical equipment, mounting electrical panels and junction boxes, securing HVAC components, and attaching plumbing fixtures or pipe supports. The inch-based sizing and Grade 5 material rating make it appropriate for moderate-strength fastening tasks where a standard zinc-plated finish provides adequate environmental protection. It pairs with 7/16 inch bolts, screws, or studs in typical shop and field assembly scenarios.

Installation Notes

Install split lock washers between the fastener head or nut and the mating surface before torquing down. De-energize electrical equipment and shut off relevant systems before performing any fastener work in live panels or mechanical assemblies. Standard hand tools apply. Do not reuse lock washers that have been fully compressed flat, as they will no longer provide effective locking action.
