Value Collection KP61012 Split Lock Washer 7/16 in 100pk

Product Description

The VALUE COLLECTION KP61012 is a Grade 2 spring steel split lock washer designed for 7/16 inch screw applications. The split lock design bites into the bearing surface and fastener to resist loosening caused by vibration and torque. This washer features a zinc plated finish that provides basic corrosion resistance for general indoor and light-duty outdoor use. With an inside diameter ranging from 0.446 to 0.459 inches and a maximum outside diameter of 0.787 inches, it conforms to standard inch-series dimensional specifications. Each pack contains 100 washers. Electricians, plumbers, HVAC technicians, and general maintenance trades commonly use split lock washers in mechanical and structural fastening assemblies.

This washer is suited for residential and commercial fastening applications where a standard 7/16 inch fastener is used and vibration resistance is required. Typical installation scenarios include equipment mounting, panel assemblies, pipe hangers, ductwork supports, and general mechanical fastening. The zinc plated finish makes it appropriate for dry or mildly humid environments. This washer is sold in a pack of 100, making it practical for production work, service truck stocking, and multi-unit installations where consistent fastener hardware is needed across multiple points.

Installation Notes

Install split lock washers between the fastener head or nut and the bearing surface before tightening. Power down or de-energize any equipment before accessing fastener assemblies on live systems. Use appropriate hand tools or power drivers calibrated to avoid over-torquing, which can flatten the washer and reduce its locking effectiveness. Follow applicable codes such as NEC or IFGC when using fastener hardware in code-governed installations.
