Value Collection LWIS1120USA-025BX Split Lock Washer 25pk

Product Description

The VALUE COLLECTION LWIS1120USA-025BX is a steel split lock washer sized for 1-1/8 inch screws and fasteners. It features a zinc plated finish that provides corrosion resistance in standard indoor and light-duty outdoor applications. The washer measures 1.129 to 1.153 inches inside diameter, 1.847 to 1.853 inches outside diameter, and 0.281 inches thick. Split lock washers work by biting into the fastener and mating surface under torque, resisting loosening caused by vibration or thermal cycling. This package contains 25 washers and is sold as a single package quantity.

Split lock washers in this size range are used across mechanical, HVAC, plumbing, and electrical trade applications wherever a standard 1-1/8 inch fastener requires vibration resistance. Common install scenarios include equipment mounting, panel attachment, pipe hanger hardware, and structural fastening in both residential and light commercial settings. The zinc plated steel construction suits general-purpose use in dry or mildly humid environments.

Installation Notes

Split lock washers are installed between the fastener head or nut and the mating surface before final torque is applied. Power down or de-energize any equipment before servicing fastened assemblies on electrical or HVAC components. Use appropriate hand tools to achieve proper clamp load without over-torquing, which can flatten the washer and eliminate its locking function. Follow applicable mechanical or electrical codes for the specific system being serviced.
