Value Collection MS35338-156 Split Lock Washer No. 8

Product Description

The VALUE COLLECTION MS35338-156 is a No. 8 split lock washer manufactured from 400 series stainless steel with a passivated finish. Designed to prevent fastener loosening under vibration and dynamic load, the split lock washer works by biting into the bearing surface and the underside of the fastener head as the assembly is torqued. The inside diameter ranges from 0.167 to 0.174 inches, the maximum outside diameter is 0.293 inches, and the nominal thickness is 0.04 inches. This washer meets MS35338 military specification requirements. Maintenance technicians, millwrights, and assembly professionals working on corrosion-resistant fastener assemblies are the primary installers.

This washer is suited for use in industrial, marine, HVAC, and mechanical assemblies where a No. 8 screw fastener requires locking action and corrosion resistance. The 400 series stainless steel base material combined with a passivated finish makes it appropriate for environments with moderate corrosive exposure. It is supplied individually but carries a minimum order quantity of 100 pieces, making it practical for bulk service inventory or production line use.
