Value Collection MS35338-137 Split Lock Washer No. 8

Product Description

The VALUE COLLECTION MS35338-137 is a No. 8 screw split lock washer manufactured from 316 stainless steel. Split lock washers are used to resist loosening of threaded fasteners caused by vibration and dynamic loading. This washer meets military specification MS35338 and complies with DFAR sourcing standards, making it suitable for government, defense, and critical commercial applications. Key dimensions are 0.167 to 0.174 inches minimum inside diameter, 0.293 inches maximum outside diameter, and 0.040 inches nominal thickness. Licensed tradespeople and maintenance technicians working on mechanical assemblies, electrical enclosures, and fluid systems install these fastener components as a standard part of bolted joint preparation.

This split lock washer is sized for No. 8 screws and is appropriate for use in applications requiring corrosion-resistant fastener hardware. The 316 stainless steel alloy provides strong resistance to chloride and marine environments, making it a common choice in coastal installations, chemical processing equipment, plumbing systems, and HVAC equipment exposed to moisture. It is sold individually but carries a minimum order quantity of 100 pieces, which aligns with typical trade and MRO procurement practices where bulk fastener quantities are standard.

Compatibility

Designed as an OEM-style replacement or standard fitment split lock washer for No. 8 screw fastener assemblies requiring MS35338-series dimensional compliance in inch-measurement applications.

Installation Notes

Split lock washers are installed between the fastener head or nut and the mating surface before torquing. Ensure the fastener assembly is fully de-energized and depressurized before servicing any bolted joints. Use appropriate hand tools and follow torque guidance specified in the equipment service documentation. Do not reuse lock washers that have been fully compressed flat, as the spring tension will be lost.
