Value Collection LWIS050USA-250BX Steel Split Lock Washer

Product Description

The VALUE COLLECTION LWIS050USA-250BX is a 1/2 inch screw-size steel split lock washer designed to resist fastener loosening caused by vibration and torque relaxation. Sold in a box of 250, these washers feature an uncoated bright finish and are manufactured to inch-system dimensions. The inside diameter ranges from 0.502 to 0.512 inches, the outside diameter ranges from 0.869 to 0.873 inches, and the washer thickness is 0.125 inches. They are installed by electricians, plumbers, HVAC technicians, and general mechanical tradespeople wherever a standard 1/2 inch fastener requires added holding force.

These split lock washers are suited for residential and light commercial mechanical assemblies, equipment mounting, and structural fastening applications. The helical split design bites into both the fastener bearing surface and the substrate when the fastener is tightened, resisting backoff under dynamic loads. The uncoated bright steel finish is appropriate for interior and dry-environment applications. The 250-piece box quantity supports production assembly, service truck stock, and maintenance shop inventory needs.

Compatibility

Designed as a standard inch-series split lock washer for use with 1/2 inch fasteners in general mechanical, electrical, plumbing, and HVAC assembly applications.

Installation Notes

Place the split lock washer between the fastener head or nut and the mating surface before torquing down. The washer should sit flat with the split gap closed upon final tightening — a gap that remains open indicates insufficient clamp load. Use with standard 1/2 inch bolts, screws, or nuts per applicable mechanical and electrical codes. The uncoated finish offers no corrosion protection, so these washers are not recommended for outdoor or high-humidity environments without additional protective measures.
