Value Collection 87925210 Split Lock Washer 5/8 in 18-8 Ss

Product Description

The VALUE COLLECTION 87925210 is a split lock washer designed for use with 5/8 inch screws and fasteners. Manufactured from 18-8 stainless steel, this spring lock washer provides reliable resistance to loosening caused by vibration, thermal cycling, and mechanical stress. The helical split design creates a spring tension that bites into the mating surface and fastener head, maintaining clamp load over time. With an inside diameter range of 0.635 to 0.65 inches and an outside diameter range of 1.079 to 1.093 inches, this washer meets dimensional requirements under ASME, ANSI, BS, DIN, JIS, and NFE standards. Thickness is 0.156 inches. Licensed tradespeople and maintenance technicians select this washer for both new installations and repairs requiring stainless corrosion resistance.

This split lock washer is suited for applications where stainless steel is required to resist corrosion in wet, outdoor, or chemically exposed environments. Common use cases include HVAC equipment mounting, plumbing system brackets, pool and spa equipment fastening, and electrical enclosure assembly. The 18-8 stainless steel grade performs reliably across a wide range of temperatures and is compatible with both standard and metric fastener assemblies using inch-system hardware. It is ordered in multiples of 100 units per purchase.

Compatibility

Designed for use with 5/8 inch screw and bolt fasteners in inch-system assemblies requiring an 18-8 stainless steel spring lock washer.

Installation Notes

Installation is performed by qualified tradespeople as part of mechanical fastening assemblies. Place the split lock washer between the fastener head or nut and the mating surface before tightening. Do not reuse a washer that has been fully compressed flat, as it will no longer provide effective spring tension. Follow applicable torque guidelines from the fastener manufacturer or relevant code requirements for the assembly type.
