Value Collection LWIS1121USA-025BX Grade 8 Split Lock Washer

Product Description

The VALUE COLLECTION LWIS1121USA-025BX is a Grade 8 split lock washer designed for use with 1-1/8 inch screws and fasteners. Made from spring steel with a yellow zinc dichromate finish, this washer delivers reliable tension and vibration resistance in high-load bolted connections. The inside diameter ranges from 1.129 to 1.153 inches, with a maximum outside diameter of 1.847 inches and a thickness of 0.281 inches. The zinc dichromate coating provides corrosion resistance suitable for demanding industrial and mechanical environments. Machinists, millwrights, pipefitters, and maintenance technicians routinely specify this grade and finish for structural and equipment assembly work.

This split lock washer is suited for use in industrial, commercial, and heavy mechanical applications where bolt loosening from vibration or dynamic loads is a concern. The Grade 8 material rating makes it appropriate for high-strength fastener assemblies in structural connections, machinery mounting, and equipment installation. It is sold in a minimum order quantity of 25 pieces per transaction, with one pack per unit as shipped.

Installation Notes

Split lock washers are installed between the fastener head or nut and the mating surface prior to final torque. Power down or de-energize any equipment before servicing bolted connections on mechanical or electrical assemblies. Use the appropriate torque specifications for the bolt grade and application as defined by the applicable engineering standard or equipment manufacturer documentation. Do not reuse compressed or fully flattened split lock washers, as they will not provide adequate locking force.
