Value Collection MS35338-44 Split Lock Washer 1/4 in

Product Description

The VALUE COLLECTION MS35338-44 is a split lock washer manufactured from spring steel and finished with a zinc yellow dichromate coating for corrosion resistance. Designed for use with 1/4-inch screws, this washer meets military specification MS35338 and provides reliable tension to resist fastener loosening under vibration and load. The washer measures 0.252 to 0.260 inches inside diameter, 0.487 inches maximum outside diameter, and 0.062 inches thick. It is a standard helical spring lock washer used across industrial, mechanical, and military-specification assemblies where fastener retention is critical.

This washer is suited for applications requiring compliance with military fastener standards, including aerospace, defense, and heavy industrial assemblies. It installs with 1/4-inch fasteners and is appropriate for use in both ferrous and non-ferrous assemblies where the zinc yellow dichromate finish provides adequate protection against oxidation. Typical installation environments include structural joints, equipment enclosures, and panel assemblies serviced by maintenance technicians and assembly professionals.

Installation Notes

Install with the split ends contacting the fastener bearing surface and the mating material to ensure proper spring action. Power down or de-energize any equipment before accessing fastened assemblies. Use calibrated torque tools appropriate to the fastener grade and application — do not over-torque, as this can flatten the washer and eliminate locking function. Consult applicable military or industry fastener standards for torque guidance specific to the assembly.
