Value Collection 31335 Grade 8 Split Lock Washer 1-1/8 in

Product Description

The VALUE COLLECTION 31335 is a Grade 8 steel split lock washer designed for use with 1-1/8 inch screws and bolts. The helical split design bites into the fastener and mating surface under torque load, resisting loosening caused by vibration and dynamic stress. The zinc-plated finish provides corrosion resistance for general indoor and light-duty outdoor applications. With an inside diameter ranging from 1.129 to 1.153 inches and a maximum outside diameter of 1.847 inches, this washer conforms to standard dimensional tolerances for 1-1/8 inch fastener hardware. Thickness is 0.345 inches. Mechanical, electrical, and plumbing contractors use this washer wherever high-strength fastening is required at the 1-1/8 inch bolt size.

This split lock washer is suited for structural assemblies, equipment mounting, panel work, and general mechanical fastening where Grade 8 material strength is specified. It is appropriate for residential and commercial construction, HVAC equipment mounting, electrical enclosure work, and industrial maintenance applications. The zinc-plated finish makes it a practical choice for use in conditioned spaces or environments with minimal moisture exposure. Sold individually; minimum order quantity is 25 pieces.

Compatibility

Designed for use with 1-1/8 inch screws and bolts where a split lock washer is specified. Suitable as a standard replacement or new-installation hardware component in mechanical, electrical, HVAC, and plumbing fastening assemblies.

Installation Notes

Install between the fastener head or nut and the mating surface with the split ends positioned to engage both surfaces as the fastener is torqued. Ensure mating surfaces are clean and free of debris before assembly. Follow applicable torque specifications for Grade 8 hardware as outlined in the relevant project or equipment documentation. No special tools are required beyond standard hand or power wrenches appropriate for the fastener size.
