Value Collection 31333 Split Lock Washer 7/8 in Grade 5

Product Description

The VALUE COLLECTION 31333 is a Grade 5 steel split lock washer sized for 7/8 inch screws and bolts. Split lock washers work by biting into both the fastener bearing surface and the mating material when torque is applied, resisting loosening from vibration and dynamic loads. This washer carries a zinc-plated finish for basic corrosion resistance in general-purpose applications. The inside diameter ranges from 0.878 to 0.894 inches with a maximum outside diameter of 1.459 inches and a thickness of 0.219 inches. Electricians, plumbers, HVAC technicians, and mechanical contractors use hardware like this daily in panel work, equipment mounting, and structural fastening tasks.

This split lock washer is suited for residential and light commercial applications where a 7/8 inch fastener is used on steel, aluminum, or other structural substrates. Typical use cases include equipment base plates, junction box hardware, bracket mounting, and general mechanical assemblies. The zinc-plated finish offers adequate protection in dry and mildly humid indoor environments. Sold individually with a minimum order quantity of 50 pieces, making it appropriate for stocking in maintenance shops, service vans, or job-site hardware bins.

Compatibility

Designed for use with 7/8 inch screws and bolts in general mechanical and structural assemblies. Consult fastener specifications to confirm ID and OD clearance requirements before installation.

Installation Notes

Install with the split ends positioned so the washer can flatten fully as the fastener is tightened. Place the split lock washer between the fastener head or nut and the mating surface. Tighten fasteners to the torque specification required by the assembly design. Follow applicable mechanical and electrical codes, such as the NEC for electrical panel and equipment mounting applications, when selecting and installing fastener hardware.
