Value Collection 239140BR External Tooth Lock Washer

Product Description

The VALUE COLLECTION 239140BR is a zinc-plated, steel external tooth lock washer designed for use with 3/4 inch screws and fasteners. With an inside diameter of 0.795 inches, an outside diameter of 1.245 inches, and a thickness of 0.055 inches, this washer uses outward-facing teeth that bite into the mating surface and fastener head to resist loosening under vibration and torque. Manufactured from Grade 2 steel with a zinc finish for corrosion resistance, it is a reliable component for mechanical assemblies across HVAC, plumbing, electrical, and general industrial applications. Installation requires no special tools and follows standard fastener assembly practice.

This external tooth lock washer is suited for residential and commercial mechanical assemblies where fastener retention under dynamic load or vibration is required. It is commonly used in equipment mounting, panel assembly, motor bracket installation, and electrical enclosure work. The zinc plating provides a baseline level of corrosion protection appropriate for indoor and sheltered applications. Sold individually per package, with a minimum order quantity of 100 pieces.
