Value Collection 86853207 Split Lock Washer 1/4 in Grade 8 50pk

Product Description

The VALUE COLLECTION 86853207 is a Grade 8 alloy steel split lock washer sized for 1/4 inch screws and finished with a zinc plating for corrosion resistance. Split lock washers provide spring tension under a fastener head or nut, resisting loosening caused by vibration or dynamic loading. This washer carries an inside diameter range of 0.252 to 0.260 inches and an outside diameter range of 0.377 to 0.487 inches, with a nominal thickness of 0.062 inches and a maximum thickness of 0.109 inches. It is sold in a package of 50 pieces. Licensed tradespeople in mechanical, HVAC, plumbing, and electrical work will encounter this fastener component in a wide range of assembly and service tasks.

This split lock washer is suited for general industrial and trade applications where a 1/4 inch fastener must be secured against vibration-induced loosening. Typical use cases include equipment panel assembly, bracket mounting, and mechanical enclosure work in both residential and light commercial settings. The Grade 8 material rating indicates a high-strength alloy steel construction, making it appropriate for higher-load connections compared to lower-grade washers. The zinc finish provides a baseline level of protection in mildly corrosive 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 performing fastener work on electrical enclosures or mechanical assemblies. Use the appropriate drive tool and follow the equipment manufacturer torque guidance for the specific fastener grade and size. Do not reuse split lock washers that have been fully compressed flat, as they will no longer provide effective locking spring force.
