Frequently Asked Questions

What is a SPEC extension spring used for?

A SPEC extension spring is used to provide a pulling force in mechanical assemblies, such as in industrial machinery, automotive components, and material handling equipment. It stores energy when stretched and returns to its original length when the load is removed.

What are the specifications of the SPEC extension spring MH03000312750M?

The SPEC extension spring MH03000312750M has a free length of 2 3/4 in, a wire diameter of 0.031 in, an outer diameter of 0.3 in, and an oil finish. It is made of music wire and comes in a 5-pack with machine hooks on each end.

How to select the right SPEC extension spring for an application?

To select the right SPEC extension spring, match the free length, wire diameter, outer diameter, and end type (machine hook) to your assembly's space and load requirements. Consider the material—music wire for fatigue resistance—and ensure the spring's maximum extension does not exceed its elastic limit.
