Product Description

The VALUE COLLECTION MS35338-50 is a split lock washer manufactured from 1060 spring steel with a zinc yellow dichromate finish. It is designed to resist fastener loosening under vibration and dynamic load conditions. The washer meets MS35338 military specification requirements, making it suitable for demanding mechanical and structural assembly applications. Inside diameter ranges from 0.628 to 0.641 inches to fit standard 5/8-inch fasteners, with a maximum outside diameter of 1.073 inches and a thickness of 0.156 inches. Machinists, maintenance mechanics, and industrial tradespeople install this type of washer as part of bolted joint assemblies across a wide range of equipment and structures.

This split lock washer is used in bolted assemblies where vibration or dynamic loading could cause fastener backoff. Typical applications include mechanical equipment mounting, structural steel connections, HVAC unit and compressor base fastening, electrical panel and enclosure assembly, and general industrial maintenance. The zinc yellow dichromate finish provides corrosion resistance in moderately exposed environments. It is sold individually per package, with a minimum order quantity of 100 pieces, making it appropriate for shop stock or production line use.

Installation Notes

Installation is performed by maintenance mechanics, millwrights, or other qualified tradespeople as part of a standard bolted joint assembly. Place the split lock washer between the fastener head or nut and the mating surface before torquing. Ensure mating surfaces are clean and free of debris before assembly. Do not reuse split lock washers that have been fully compressed or show deformation, as spring action will be reduced.
