Value Collection VW4020PS External Tooth Lock Washer

Product Description

The VALUE COLLECTION VW4020PS is a 2 screw external tooth lock washer made from Grade 410 stainless steel. It features a 0.123 inch inside diameter and a 0.26 inch outside diameter, with a thickness of 0.018 inches. The external tooth design bites into the mating surface and fastener bearing face to resist loosening under vibration and torque. At a hardness of 40-50 HRC, the washer maintains grip without deforming under load. This washer is suited for mechanical, electrical, and plumbing panel assemblies where a secure, corrosion-resistant fastening solution is required. Installation is performed by maintenance technicians, electricians, and plumbers working with number 2 screw fasteners.

This external tooth lock washer is used in light-duty fastener assemblies requiring vibration resistance and corrosion protection. Typical applications include electrical enclosure assembly, HVAC cabinet construction, plumbing fixture mounting, and general mechanical assemblies where number 2 screws are used. The Grade 410 stainless steel construction provides moderate corrosion resistance suitable for indoor and sheltered outdoor environments. This washer is sold individually but requires a minimum order of 100 units per transaction.
