Hillman Fasteners 540845 Extension Spring Steel 6 Pack

Product Description

The HILLMAN FASTENERS 540845 is a standard extension spring designed for conventional tensile-force applications across a wide range of trade and mechanical uses. Constructed from steel with a zinc finish for basic corrosion resistance, this spring returns to its original length when a load is removed, making it suitable for linkages, latches, garage hardware, and general mechanical assemblies. Each order includes six springs packaged in a poly bag, with a combined package weight of 0.81 pounds. Installation requires no special tooling beyond standard spring hooks or attachment hardware appropriate to the application.

This extension spring is a general-purpose component suited for light mechanical assemblies in residential and commercial settings. Typical applications include door and gate hardware, HVAC damper linkages, equipment panels, and other assemblies that require a spring-return or tensioning force. The zinc finish provides modest protection in dry or low-humidity indoor environments. Sold in a six-pack, it is appropriate for both single repairs and small-volume stocking by trade professionals.

Installation Notes

Extension springs should be installed by a qualified technician familiar with spring-loaded hardware. Always relieve any existing tension before removing a worn spring, and confirm that hook or loop attachment points are rated for the intended load. Inspect mounting hardware for wear or damage prior to installing a replacement spring.
