Product Description

The VALUE COLLECTION LWIS1251USA-025BX is a Grade 8 spring steel split lock washer designed for 1-1/4 inch screw applications. It features a zinc yellow dichromate finish that provides corrosion resistance in demanding environments. The washer measures 1.254 inches minimum inside diameter, up to 1.280 inches maximum inside diameter, with a maximum outside diameter of 2.036 inches and a thickness of 0.312 inches. Split lock washers of this grade are installed by maintenance professionals, millwrights, and structural technicians where fastener loosening from vibration or dynamic loading is a concern. This package contains a minimum order quantity of 25 pieces.

This split lock washer is suited for heavy-duty bolted assemblies in industrial, mechanical, and structural applications. Grade 8 spring steel provides the hardness and tensile strength required for high-load fastening points. The yellow zinc dichromate finish offers added protection against oxidation in both indoor and outdoor installations. Typical use cases include machinery mounts, steel fabrication, equipment bases, and general MRO fastening where a standard SAE split lock washer is specified. The inch measurement system makes this washer compatible with standard fractional hardware in North American trade applications.

Installation Notes

Split lock washers are installed by mechanics, millwrights, and structural tradespeople using standard hand or power tools. Always place the split lock washer between the fastener head or nut and the mating surface before torquing. Ensure fastener threads and seating surfaces are clean and free of debris before assembly. Do not reuse lock washers that have been fully compressed flat, as locking effectiveness is reduced.
