Value Collection C602415 Hex Nut Lock Washer Zinc 50pk

Product Description

The VALUE COLLECTION C602415 is a combined hex nut and external tooth lock washer assembly finished in zinc plating for corrosion resistance in standard indoor and light-duty applications. The external tooth configuration bites into the mating surface and the underside of the nut, resisting loosening caused by vibration and torque. The washer has an outside diameter of 0.61 inches and the assembly meets ASME B18.21.1 dimensional standards. This package contains 50 pieces, making it a practical stock item for electrical, mechanical, and general fastening tasks on the bench or in the field.

These assemblies are used wherever a hex nut and lock washer are required in a single fastener, eliminating the need to handle two separate components during installation. Common applications include electrical panel and enclosure work, HVAC equipment mounting, light structural assemblies, and general trade use in residential and light commercial settings. The zinc plating suits dry or occasionally damp indoor environments. Sold in a 50-piece pack, this SKU is suited for contractors and shops maintaining a working fastener inventory.

Installation Notes

These fasteners are typically installed by electricians, HVAC technicians, plumbers, and general mechanical trades. De-energize any electrical equipment and follow applicable lockout/tagout procedures before working in panels or enclosures. Hand-tighten first to confirm thread engagement, then bring to snug with an appropriate wrench. External tooth lock washers are not recommended on soft or easily marred surfaces where the teeth may cause damage.
