Value Collection 88548631 Split Lock Washer 1/4 in 50-pack

Product Description

The VALUE COLLECTION 88548631 is an alloy steel split lock washer sized for 1/4 inch screws. Split lock washers are used under fastener heads or nuts to resist loosening caused by vibration and torque. The helical split design bites into both the fastener bearing surface and the mating material, creating resistance against rotation. These washers are supplied in an uncoated, bright finish and are sold in a pack of 50. The inside diameter ranges from 0.255 to 0.263 inches, the maximum outside diameter is 0.365 inches, and the thickness is 0.078 inches. Licensed tradespeople in HVAC, plumbing, electrical, and mechanical service work use split lock washers as standard hardware in panel, bracket, and equipment mounting applications.

This washer is suited for general mechanical assembly and equipment installation work where vibration resistance is needed at the fastener joint. Typical applications include securing control panels, mounting brackets, motor housings, and structural components in residential and commercial trade settings. The alloy steel construction provides greater hardness and spring tension than standard low-carbon steel washers, making these appropriate for higher-load or higher-vibration installations. The bright, uncoated finish is standard for interior or protected environments where corrosion is not a primary concern.

Key Features

Compatibility

Designed for use with standard 1/4 inch fasteners in general mechanical, electrical, and HVAC equipment assembly applications where a split lock washer is specified.

Installation Notes

Split lock washers are installed between the fastener head or nut and the mating surface before torquing the fastener. De-energize all electrical equipment and shut off any fluid or gas supply before servicing panels or assemblies that require fastener removal. Use the appropriate hand tools or a calibrated torque wrench per the equipment manufacturer's fastener specifications. Verify finish compatibility with the installation environment, as the uncoated bright finish is not rated for outdoor or high-humidity exposure without additional corrosion protection.
