Value Collection R63082641 External Tooth Lock Washer

Product Description

The VALUE COLLECTION R63082641 is a stainless steel external tooth lock washer sized for 5/16 inch screws. It features an inside diameter of 0.332 inches and an outside diameter of 0.61 inches, with a thickness of 0.034 inches. Manufactured from Grade 410 stainless steel, it delivers reliable corrosion resistance and solid clamping force in mechanical and structural fastening applications. The external tooth configuration bites into the mating surface and fastener head to resist loosening under vibration and dynamic loads. Electricians, plumbers, HVAC technicians, and general maintenance trades use these washers wherever a secure, vibration-resistant fastened joint is required.

This washer is suited for use in residential and light commercial mechanical, electrical, and plumbing assemblies where stainless steel hardware is specified for corrosion resistance. It is appropriate for indoor and outdoor installations where standard carbon steel fasteners are not acceptable due to moisture exposure or chemical environments. The external tooth design makes it a common choice for sheet metal, electrical panel, and equipment enclosure work where positive locking is needed without adhesive thread-locking compounds.

Installation Notes

Install with the teeth facing the fastener head or the mating surface, not against a hardened washer, to allow the teeth to engage properly. De-energize all electrical circuits and depressurize or shut off any fluid systems before servicing fastened connections in live panels or piping. Standard hand tools apply; no special tooling is required for washer installation.
