Value Collection R63082449 Internal Tooth Lock Washer

Product Description

The VALUE COLLECTION R63082449 is a No. 6 screw internal tooth lock washer manufactured from Grade 410 stainless steel. Internal tooth lock washers grip mating surfaces on both faces, resisting loosening caused by vibration and torque. The R63082449 measures 0.15 inches inside diameter and 0.295 inches outside diameter, with a thickness of 0.021 inches. Grade 410 stainless steel provides corrosion resistance and hardness suitable for demanding mechanical assemblies. Electricians, HVAC technicians, plumbers, and general tradespeople use internal tooth lock washers in panel assemblies, equipment enclosures, and fastened connections where vibration resistance is required.

This washer is sized for a No. 6 screw and is suited to residential and light commercial applications. Common install scenarios include electrical panel components, control board mounting hardware, equipment enclosure fasteners, and any bolted joint requiring positive locking action under vibration. The stainless steel construction makes it appropriate for both indoor and outdoor environments where mild corrosion resistance is needed. This part is sold individually, with a minimum order quantity of 500 pieces.

Installation Notes

Internal tooth lock washers are installed between the fastener head and the mating surface before tightening. Power down or de-energize any assembly before servicing fastened connections in electrical or HVAC panels. Use appropriate hand tools and follow applicable codes such as the NEC for electrical assemblies. Do not reuse lock washers that have been fully compressed or deformed, as locking effectiveness is reduced.
