Product Description

The VALUE COLLECTION LWHIS0430USA-100BX is a Grade 2 spring steel split lock washer designed for use with 7/16-inch screws and fasteners. The helical split design bites into the mating surface under load, resisting loosening caused by vibration, torque, or thermal cycling. With a zinc plated finish providing basic corrosion resistance, this washer suits general-purpose mechanical assemblies across industrial, HVAC, plumbing, and electrical applications. The inside diameter measures 0.44 inches minimum and 0.45 inches maximum, with a maximum outside diameter of 0.784 inches and a thickness of 0.133 inches. This box contains a minimum order quantity of 100 washers sold as a single package unit.

This split lock washer is appropriate for a wide range of residential and light commercial fastening applications where a standard 7/16-inch threaded fastener is used. Common installation scenarios include equipment mounting, panel assembly, pipe hanger hardware, and general mechanical connections where vibration resistance is required. The zinc plated finish suits indoor and low-moisture environments. Trades including HVAC technicians, plumbers, electricians, and millwrights routinely use this washer type during equipment installation and maintenance work.

Installation Notes

Installation is performed by any trade working with standard threaded fasteners. Place the split lock washer on the fastener shank between the nut or bolt head and the mating surface before tightening. Ensure the fastener and mating material are clean and free of debris prior to assembly. Do not reuse split lock washers that have been fully compressed or deformed, as they will not provide adequate locking force.
