Value Collection MS35338-142 Split Lock Washer 7/16 in 316 Ss

Product Description

The VALUE COLLECTION MS35338-142 is a split lock washer designed to resist loosening in bolted assemblies subject to vibration, torque cycling, and thermal expansion. Manufactured from 316 stainless steel, this washer provides strong corrosion resistance in wet, chemical, and marine environments. It fits a 7/16 inch screw and measures 0.44 to 0.45 inches ID, 0.776 inches maximum OD, and 0.109 inches thick. The part meets Military Specification MS35338, making it suitable for demanding applications where fastener retention is critical. Maintenance technicians, pipefitters, and HVAC service pros use this type of hardware in corrosive or high-moisture installations.

This split lock washer is used in residential and commercial mechanical systems where stainless fasteners are required to resist rust and galvanic corrosion. Typical applications include HVAC equipment mounting, plumbing fixture assembly, pool and spa mechanical enclosures, and marine or coastal equipment installations. The 316 alloy grade is well suited for environments exposed to chlorides, saltwater, or cleaning chemicals. The washer installs under the fastener head or nut to maintain clamp load and prevent backing out over time.

Compatibility

Designed as a standard MS35338-series split lock washer for 7/16 inch screw sizes, suitable for use in any bolted assembly calling for a 316 stainless steel split lock washer per the MS35338 fastener standard.

Installation Notes

Install this washer between the fastener head or nut and the mating surface before torquing. De-energize or shut off any equipment before performing hardware service on mechanical assemblies. Use the appropriate hand tools or torque wrench per the equipment manufacturer specifications. Avoid mixing stainless steel fasteners with dissimilar metals without proper isolation to minimize galvanic corrosion risk.
