Value Collection HLWIA037USA-100BX Lock Washer 3/8 in

Product Description

The VALUE COLLECTION HLWIA037USA-100BX is a high-collar split lock washer designed for 3/8-inch fastener applications. Manufactured from steel with a bright, uncoated finish, this washer provides mechanical resistance to loosening under vibration and torque loads. The high-collar design increases the contact surface between the fastener and the mating component, improving load distribution compared to standard split lock washers. With an inside diameter of 0.382 inches and a maximum outside diameter of 0.553 inches, it is dimensionally suited for standard 3/8-inch fastener assemblies across a range of trade and industrial applications. This box contains 100 washers sold as a single package quantity.

High-collar split lock washers like the HLWIA037USA-100BX are commonly used in HVAC equipment assembly, electrical panel mounting, plumbing fixture installation, and general mechanical fastening where vibration or thermal cycling may cause standard fasteners to back out over time. Suitable for use wherever a 3/8-inch screw or bolt requires additional locking force at the joint interface. The steel construction and uncoated finish make these appropriate for indoor and dry-environment installations where corrosion resistance is not the primary concern.

Compatibility

Designed as a standard-dimension replacement or stock component for 3/8-inch screw and bolt assemblies requiring a high-collar split lock washer in inch-measurement fastener systems.

Installation Notes

Install with the split ends oriented against the fastener and the mating surface as intended by the assembly design. Power down or de-energize any electrical or mechanical system before servicing fastened connections. These washers do not meet military specifications and should not be used in applications requiring MIL-spec compliance. General mechanical and electrical installations should follow applicable codes such as the NEC or equipment manufacturer torque guidelines where specified in the service documentation.
