Value Collection MS35338-135 Split Lock Washer 316 Ss

Product Description

The VALUE COLLECTION MS35338-135 is a No. 4 screw split lock washer made from 316 stainless steel. It provides a helical spring tension that resists loosening caused by vibration and torque relaxation in threaded fastener assemblies. The washer measures 0.114 to 0.120 inches minimum inside diameter, 0.209 inches maximum outside diameter, and 0.025 inches nominal thickness. Manufactured to meet military specification MS35338 and DFAR compliance requirements, this washer is suited for applications where corrosion resistance and fastener retention are both required. Installation is performed by maintenance technicians, assemblers, and trade professionals working with small-diameter fasteners in corrosive or marine-adjacent environments.

This split lock washer is intended for use with No. 4 screw fasteners in light-duty mechanical and electrical assemblies, enclosure hardware, panel mounting, and equipment fabrication. The 316 stainless steel construction makes it appropriate for wet, coastal, or chemically exposed service environments where standard 18-8 stainless may be insufficient. It is commonly used in HVAC equipment assemblies, electrical panel hardware, plumbing fixture mounting, and similar trade applications requiring small-diameter corrosion-resistant hardware. Minimum order quantity is 100 pieces per order.

Key Features

• 316 stainless steel construction provides elevated corrosion resistance compared to standard 18-8 grades
• Meets military specification MS35338 for split lock washers
• DFAR-compliant material sourcing
• Sized for No. 4 screw fasteners with 0.114 to 0.120 inches inside diameter
• 0.209 inches maximum outside diameter and 0.025 inches nominal thickness
• Helical split design creates spring tension to resist vibration-induced loosening

Compatibility

Designed for use with No. 4 screw fasteners conforming to the MS35338 fastener standard in inch-measurement assemblies.

Installation Notes

Install the split lock washer between the fastener head or nut and the mating surface before final torque is applied. Power down or de-energize any assembly before servicing fastener hardware in electrical or control enclosures. Use calibrated hand tools appropriate for small No. 4 fasteners to avoid deforming the washer. Verify DFAR compliance documentation requirements are met for government or defense-related work prior to installation.
