Value Collection MS35338-48 Split Lock Washer 1/2 in

Product Description

The VALUE COLLECTION MS35338-48 is a split lock washer manufactured from 1060 spring steel and finished with a yellow zinc dichromate coating for corrosion resistance. Designed for use with 1/2-inch screws, this washer features an inside diameter ranging from 0.502 to 0.512 inches and a maximum outside diameter of 0.889 inches, with a nominal thickness of 0.125 inches. It meets military specification MS35338, making it appropriate for applications that require documented fastener standards. Machinists, maintenance technicians, millwrights, and assembly professionals install this washer to prevent fastener back-out under vibration and dynamic loading conditions.

This split lock washer is suited for general industrial, military, and MRO fastener applications where a 1/2-inch screw or bolt requires rotational resistance. The yellow zinc dichromate finish provides a baseline level of corrosion protection in moderate-exposure environments. It is commonly used in equipment assembly, structural fastening, and machinery maintenance across industrial and government maintenance operations. This item is sold individually but carries a minimum order quantity of 100 pieces.

Installation Notes

Install this washer between the fastener head or nut and the mating surface, with the split gap oriented so the washer bites into both surfaces as the fastener is tightened. Ensure the mating fastener thread and bearing surface are clean and free of debris before assembly. Always torque fasteners according to the assembly specification for the application rather than the washer alone. Follow applicable military or industrial fastener standards when used in specification-controlled assemblies.
