Value Collection R63082069 External Tooth Lock Washer

Product Description

The VALUE COLLECTION R63082069 is a stainless steel external tooth lock washer designed for use with 1/4 inch screws. It features an inside diameter of 0.267 inches and an outside diameter of 0.51 inches, with a thickness of 0.028 inches. Manufactured from Grade 410 stainless steel, this washer provides reliable corrosion resistance and holding strength under vibration. The external tooth configuration bites into the mating surface and fastener head to resist loosening during service. This washer is a standard hardware component installed by electricians, HVAC technicians, plumbers, and general trade professionals wherever a secure, vibration-resistant fastener assembly is required.

External tooth lock washers in this size range are commonly used in light mechanical assemblies, electrical panel work, HVAC equipment mounting, and plumbing fixture installations. The Grade 410 stainless steel construction makes this washer suitable for indoor and moderate outdoor environments where mild corrosion resistance is needed. This item is sold individually but requires a minimum order quantity of 100 units, making it appropriate for stocking in trade shops, maintenance departments, or service vehicles that handle recurring fastener needs.
