Gardner Spring 36458G Precision Compression Spring

Product Description

The GARDNER SPRING 36458G is a precision compression spring manufactured from music wire (AISI 302 / ASTM A228 / ASTM A313) with a plain finish. It measures 0.48 inches outside diameter and 1 inch free length, with a wire diameter of 0.0382 inches. The spring delivers a rate of 9 pounds per inch and handles a maximum working load of 6 pounds. Closed and ground ends provide stable seating and consistent load transfer. This spring suits mechanical assemblies, valve components, tooling fixtures, and light-duty industrial applications where repeatable spring force and dimensional precision are required.

The 36458G fits into assemblies with a hole diameter of 0.50 inches and has a solid height of 0.229 inches. Its compact profile and music wire construction make it a common choice in HVAC controls, plumbing valve mechanisms, electrical panel hardware, and general mechanical assemblies. The silver plain finish is appropriate for dry or lightly protected indoor environments. Professionals and procurement teams working on small-batch repairs or production assemblies can source this spring individually or in multi-piece packaging quantities.

Key Features

• Music wire construction meets AISI 302, ASTM A228, and ASTM A313 standards
• 0.48 inch outside diameter fits 0.50 inch hole diameter clearance
• 9 pounds per inch spring rate for consistent, predictable load response
• 6 pound maximum working load with closed and ground ends for stable seating
• Solid height of 0.229 inches allows compact installation in tight assemblies
• Plain silver finish suitable for indoor mechanical assemblies

Compatibility

Designed as a precision replacement or new-build compression spring for mechanical assemblies requiring a 0.48 inch outside diameter, 1 inch free length, and 9 pound per inch spring rate in a closed and ground end configuration.

Installation Notes

Installation is typically performed by mechanical technicians, HVAC service professionals, or maintenance personnel working on valve, actuator, or control assemblies. Power down or depressurize the assembly before removing or installing compression springs to prevent uncontrolled release of stored energy. Verify that the mating bore diameter and pocket depth are consistent with the spring dimensions before seating. Do not exceed the rated maximum working load during installation or operation.
