Made of stainless steel, these springs are more corrosion resistant than steel extension springs. Keep them on hand so you can cut the right length whenever you need it. All have straight-cut ends, which allow you to bend the end coils into hook or loop ends.

As you stretch an extension spring, it gets harder to pull. Minimum load is the amount of force required to start to extend the spring. Spring rate is the amount of force required for every inch of extension.

To determine the spring rate of a cut spring, first multiply the spring’s original length by the spring rate given, then divide the result by the cut length (in inches).

A black-oxide finish provides these steel anchors with mild corrosion resistance. The head swivels 360° so the spring stays straight and properly coiled. Attach an extension spring to a stud and then thread the stud into your part for a secure connection. To make tightening easier, anchors have a hex socket on the bottom and wrench flats at the top of the threads.
