Value Collection 31341 External Tooth Lock Washer No. 8 100pk

Product Description

The VALUE COLLECTION 31341 is a No. 8 screw external tooth lock washer made from Grade 2 steel with a zinc-plated finish. The external tooth design bites into the mating surface to resist loosening from vibration and rotation, making it a dependable fastening component in light-duty mechanical and electrical assemblies. The washer measures 0.02 inches thick, with an inside diameter ranging from 0.168 to 0.176 inches and an outside diameter ranging from 0.37 to 0.381 inches. Sold in a pack of 100, this item suits shops and technicians who need reliable inventory on hand for routine service and assembly work.

This lock washer is suited for residential and light commercial applications where a No. 8 screw is used to secure panels, junction boxes, equipment covers, brackets, and similar hardware. Electricians, HVAC technicians, and general mechanical trade workers commonly use external tooth lock washers in control panel assemblies, equipment mounting, and sheet metal work where maintaining clamp load is important. The zinc plating provides basic corrosion resistance for indoor and sheltered outdoor use.

Installation Notes

Install with the teeth facing the surface that requires grip, not the fastener head side, to maximize locking effectiveness. Power down or de-energize any electrical assembly before adding or replacing hardware. Use appropriate hand tools and follow applicable NEC or equipment manufacturer guidelines when installing hardware inside electrical enclosures. Inspect washers for deformation before installation and discard any that are bent or cracked.
