Value Collection MS35338-154 Split Lock Washer No. 4

Product Description

The VALUE COLLECTION MS35338-154 is a No. 4 split lock washer manufactured to military specification MS35338, designed to prevent fastener loosening under vibration and dynamic load conditions. Constructed from 400 series stainless steel with a passivated finish, this washer resists corrosion in demanding environments. The inside diameter ranges from 0.114 to 0.120 inches with a maximum outside diameter of 0.209 inches and a nominal thickness of 0.025 inches. It is used by mechanical assemblers, maintenance technicians, and tradespeople wherever a No. 4 fastener requires positive locking retention in a corrosion-resistant application.

This split lock washer is suited for light-duty mechanical assemblies, control panel hardware, instrumentation enclosures, and similar applications where a No. 4 screw is specified. Its compliance with the MS35338 military fastener standard makes it appropriate for applications requiring documented material and dimensional conformance. The passivated stainless steel finish supports use in environments with moderate moisture or chemical exposure. Sold individually per package; minimum order quantity is 100 pieces.
