Value Collection 06878151 Steel Lock Washer Assortment

Product Description

The VALUE COLLECTION 06878151 is a 235-piece steel lock washer assortment covering thread sizes from 3/16 inch to 1/2 inch. Lock washers resist fastener loosening caused by vibration, thermal cycling, and mechanical stress — making them a staple in HVAC equipment assemblies, electrical panel work, plumbing fixture mounting, and general mechanical installations. The set ships in a labeled plastic storage case that keeps sizes separated and accessible on the job or at the bench. At 1.7 pounds, the case is light enough to carry in a service bag. This assortment suits technicians who need a range of sizes on hand without stocking individual lots.

This assortment is suited for residential and light commercial applications where standard fractional thread sizes are common. Typical uses include securing cabinet panels, motor mounts, junction box hardware, fan blade assemblies, and pipe hanger hardware. The range from 3/16 inch to 1/2 inch covers the most frequently encountered fastener sizes in HVAC, electrical, and plumbing service work. The plastic case makes it practical for truck-stock or shop inventory.

Installation Notes

Lock washers are installed between the fastener head or nut and the mating surface before final torque is applied. Ensure the fastener thread size matches the washer inner diameter before installation. Power down or de-energize any equipment before servicing fastened assemblies on electrical or HVAC components. Follow applicable NEC or equipment manufacturer guidelines when securing hardware inside energized enclosures.
