Gardner Spring 36058G Precision Compression Spring

Product Description

The GARDNER SPRING 36058G is a precision compression spring manufactured from AISI 302 music wire with a plain silver finish. It features a 0.36-inch outside diameter, a 0.75-inch free length, and a 0.026-inch wire diameter. The spring delivers a 6 lb/in spring rate and handles a maximum work load of 3.5 pounds (15.57 N). Closed and ground ends provide stable seating and consistent load transfer. This spring is suited for light-duty mechanical assemblies, instrumentation, valves, and industrial equipment where repeatable deflection and compact sizing are required. Licensed technicians and mechanical assemblers are the typical installers.

The 36058G fits applications requiring a small-diameter compression spring in a confined space. Its 0.375-inch hole diameter clearance and 0.138-inch solid height make it appropriate for tight-tolerance assemblies in HVAC controls, pneumatic valves, fluid control components, and precision mechanical devices. The music wire construction meets AISI 302, ASTM A228, and ASTM A313 standards, making it suitable for general industrial and OEM assembly environments where consistent spring force at low deflection is critical.

Key Features

• Closed and ground ends for flat, stable seating and accurate load application
• 6 lb/in spring rate for predictable, linear deflection behavior
• Maximum work load of 3.5 pounds supports light-duty mechanical actuation
• Music wire construction meets AISI 302, ASTM A228, and ASTM A313 standards
• 0.138-inch solid height enables use in highly compressed, space-constrained assemblies
• Plain silver finish - no coating to affect dimensional tolerances

Compatibility

Designed as an OEM-style precision compression spring for light-duty mechanical assemblies requiring a 0.36-inch OD and 0.75-inch free length in closed and ground end configuration.

Installation Notes

Installation is performed by mechanical assemblers or qualified technicians working on the host equipment. De-energize and depressurize any system before replacing internal springs. Verify hole diameter clearance of 0.375 inches and confirm the solid height of 0.138 inches is compatible with the available travel in the assembly. Avoid over-compressing beyond the rated maximum work load, as this can cause permanent set and reduce spring service life.
