1/4 in Split Lock Washer

Short Description

Steel 1/4 in split lock washer for machine-fastened assemblies requiring added spring tension against loosening. Matching listings show zinc-plated steel, ASME B18.21.1 dimensional standard, 1/4 in screw size, about 17/64 in max inside diameter, about 31/64 in max outside diameter, and about 1/16 in thickness for this size class.

Product Overview

The SystemShield 1/4 in Split Lock Washer is a spring-type locking washer intended for use in bolted and machine-fastened assemblies where added resistance to backing-off from mild vibration or joint relaxation is required. Split lock washers are semi-coiled washers with an opening where one side rises above the other; when compressed, they push back against the mating surfaces to help resist loosening.

For the 1/4 in size class, matching listings show a steel washer with zinc-plated finish, sized for 1/4 in screw/bolt hardware and built to ASME B18.21.1. Matching dimensional data shows about 0.252 to 0.260 in inside diameter on one listing, or 1/4 in min to 17/64 in max inside diameter on another. Outside diameter is shown at about 0.489 in max or 31/64 in max, and thickness is shown at about 1/16 in.

This washer format is commonly used under a nut or bolt head in a stacked hardware joint where a basic lock-washer function is desired along with compatibility with standard 1/4 in hardware systems.
