Value Collection 239150BR External Tooth Lock Washer 7/8 in

Product Description

The VALUE COLLECTION 239150BR is a zinc-plated, Grade 2 steel external tooth lock washer designed for use with 7/8 inch screws and fasteners. With an inside diameter of 0.927 inches and an outside diameter of 1.41 inches, this washer seats securely against a fastener head or nut to resist loosening caused by vibration and torque. The external tooth design bites into both the mating surface and the fastener, creating a mechanical lock. At 0.06 inches thick and weighing 0.02 pounds, it is a standard hardware component used across HVAC, plumbing, electrical, and general mechanical assembly applications.

This external tooth lock washer is suited for residential and light commercial mechanical assemblies where vibration resistance is required. It is appropriate for use wherever a Grade 2 steel zinc-plated washer is specified alongside 7/8 inch fasteners. Typical applications include equipment panel assembly, ductwork hardware, electrical enclosures, and general structural fastening. This item is sold individually but carries a minimum order quantity of 100 pieces per order.
