Value Collection LWIS0-8USA-500BX No. 8 Split Lock Washer

Product Description

The VALUE COLLECTION LWIS0-8USA-500BX is a No. 8 split lock washer manufactured from steel with a bright, uncoated finish. Designed to resist fastener back-off caused by vibration and torque relaxation, the split lock washer bites into both the bearing surface and the fastener underhead as the fastener is tightened. Inside diameter ranges from 0.167 to 0.174 inches, outside diameter ranges from 0.293 to 0.307 inches, and thickness is 0.04 inches. This listing covers a minimum order quantity of 500 pieces, packaged as a single unit. Electricians, HVAC technicians, plumbers, and mechanical contractors use these washers in a wide range of equipment assembly and service applications.

No. 8 split lock washers are used wherever a No. 8 machine screw or equivalent fastener requires a locking element to maintain clamp load under vibration or thermal cycling. Common applications include electrical panel assembly, HVAC unit housing fastening, sheet metal work, and light mechanical assembly. The uncoated bright finish is appropriate for interior or protected installations where corrosion exposure is limited. The 500-piece box quantity suits service shops, maintenance contractors, and assembly operations that need consistent on-hand supply.

Installation Notes

Install split lock washers between the fastener head and the mating surface before driving the screw to its final torque. Ensure the split ends are fully compressed and flush after tightening, which confirms proper clamping action. These washers are intended for use in dry or protected interior locations; consult application requirements before using in corrosive or outdoor environments where a coated or stainless fastener system may be more appropriate. No special tools are required beyond standard hand or power fastening equipment.
