Value Collection LWIS0-5USA-500BX No. 5 Split Lock Washer

Product Description

The VALUE COLLECTION LWIS0-5USA-500BX is a No. 5 screw-size split lock washer manufactured from uncoated steel. Split lock washers apply spring tension under a fastener head or nut, resisting loosening caused by vibration and thermal cycling. This washer has an inside diameter of 0.127 to 0.133 inches, an outside diameter of 0.236 to 0.252 inches, and a thickness of 0.031 inches. The bright, uncoated finish leaves the steel in its natural state. Supplied in a box quantity of 500, this part suits high-volume assembly work, production runs, and maintenance stock across industrial, mechanical, and light construction applications.

This split lock washer is sized for No. 5 machine screws and is suited for use in general-purpose fastening applications where vibration resistance is needed. Typical uses include panel assembly, equipment mounting, and electrical enclosure work where small-screw hardware is specified. The inch-measurement sizing makes it compatible with standard inch-series fastener systems. The 500-count box quantity supports production and shop floor use where bulk supply reduces restocking interruptions.

Compatibility

Designed for use with No. 5 inch-series machine screws in general-purpose fastening assemblies requiring a standard split lock washer.

Installation Notes

Split lock washers are installed between the fastener head or nut and the mating surface before the fastener is driven to final torque. Power down or de-energize any equipment before servicing fastened assemblies. Do not reuse deformed or flattened lock washers, as a washer that has been fully compressed no longer provides effective spring tension. Installation is appropriate for any trade working with No. 5 screw-size hardware in mechanical or electrical assemblies.
