Value Collection C14611 Internal Tooth Lock Washer 100 Pack

Product Description

The VALUE COLLECTION C14611 is a zinc-plated, Grade 2 steel internal tooth lock washer sized for No. 10 screws. Internal tooth lock washers grip both the fastener head and the mating surface simultaneously, resisting loosening caused by vibration and torque. The serrated teeth bite into the material as the fastener is tightened, maintaining clamp load over time. This washer measures 0.025 inches thick with a minimum inside diameter of 0.195 inches and a maximum inside diameter of 0.204 inches. Outside diameter ranges from a minimum of 0.494 inches to a maximum of 0.506 inches. Sold in a package of 100. Electricians, HVAC technicians, plumbers, and general tradespeople keep these on hand for routine panel, bracket, and equipment fastening tasks.

Internal tooth lock washers of this type are used across residential and light commercial applications wherever a No. 10 machine screw, bolt, or similar fastener must resist vibration-induced loosening. Typical installations include electrical enclosures, control panels, HVAC equipment cabinets, sheet metal assemblies, and mechanical brackets. The zinc plating provides basic corrosion resistance suitable for indoor and mildly exposed environments.

Installation Notes

Internal tooth lock washers are installed by tradespeople as part of standard fastener assemblies in panels, enclosures, and equipment frames. Place the washer between the fastener head and the mating surface before tightening. De-energize any electrical equipment and follow applicable NEC guidelines before working inside enclosures. Do not reuse lock washers that have been fully compressed or deformed, as tooth engagement will be reduced.
