Gardner Spring 36005G Precision Compression Spring

Product Description

The GARDNER SPRING 36005G is a precision compression spring manufactured from music wire with a plain silver finish. It measures 0.12 inches in outside diameter and 0.75 inches in free length, with a wire diameter of 0.0181 inches and a solid height of 0.351 inches. The spring delivers a maximum work load of 3.5 pounds and a spring rate of 8.5 pounds per inch. Built to close tolerances, it suits applications where consistent force and reliable cycling are required in compact assemblies. Installation is performed by mechanical technicians and assembly professionals working with small-component mechanisms.

This compression spring fits compact mechanical assemblies across industrial, commercial, and light-duty applications where a small-diameter, short-length spring is needed to provide controlled resistance or return force. Its closed and ground ends provide stable seating and even load distribution. Typical use cases include instrument components, valve assemblies, small actuators, and general mechanical sub-assemblies requiring a precision-class spring in the 0.12 inch OD range.

Key Features

• Precision-class compression spring with closed and ground ends for stable load bearing
• Outside diameter of 0.12 inches fits a hole diameter of 0.125 inches
• Music wire construction meets AISI 302, ASTM A228, and ASTM A313 standards
• Spring rate of 8.5 pounds per inch with maximum work load of 3.5 pounds (15.57 N)
• Plain silver finish suitable for general indoor mechanical environments
• Solid height of 0.351 inches limits compression travel in tight assemblies

Compatibility

Designed as a precision compression spring for compact mechanical assemblies requiring a 0.12 inch outside diameter and 0.75 inch free length in music wire construction.

Installation Notes

This spring is installed by mechanical assemblers or technicians working on small-component mechanisms. Ensure the mating bore or hole diameter is compatible before installation - the specified hole diameter for this spring is 0.125 inches. Avoid overcompressing the spring past its solid height of 0.351 inches, as doing so will cause permanent set and loss of rated load capacity. Use appropriate small-parts handling tools to avoid deforming the spring during installation.
