Value Collection MSC-67498600 Split Lock Washer 5/16 in

Product Description

The VALUE COLLECTION MSC-67498600 is a silicon bronze split lock washer sized for 5/16 inch screws. Split lock washers create spring tension when a fastener is tightened, resisting loosening caused by vibration and thermal cycling. This washer is manufactured to ASME B18.21.1 standards, ensuring consistent dimensional tolerances across production runs. With an inside diameter of 0.314 inches, an outside diameter ranging from 0.583 to 0.586 inches, and a thickness of 0.078 inches, it fits standard 5/16 inch fastener assemblies. Silicon bronze construction provides corrosion resistance in wet, marine, and chemically active environments where steel hardware would be unsuitable. Plumbers, marine electricians, and industrial maintenance technicians commonly specify silicon bronze hardware for these conditions.

This split lock washer is appropriate for use in plumbing, marine, coastal, and light industrial fastening applications where corrosion resistance is a primary requirement. Silicon bronze is compatible with copper and brass fittings, making it a common choice in plumbing assemblies and electrical grounding connections where galvanic compatibility matters. It is suited for both residential and commercial installations. Sold individually per package with a minimum order quantity of 100 units.

Compatibility

Designed for use with standard 5/16 inch fasteners in applications requiring silicon bronze hardware per ASME B18.21.1 specifications.

Installation Notes

Install with the split gap oriented away from the bearing surface before seating the fastener. Tighten fasteners to the torque specification required by the joint design, not to a value specific to this washer. Power down or depressurize any system before servicing fastened connections in live plumbing or electrical assemblies. Consult applicable NEC or IPC sections when using in electrical or plumbing installations.
