How To Measure Your 15/64" Inner Diameter Stock Extension Spring




Your 15/64" (fifteen sixty-fourths of an inch) extension spring’s outer diameter is a critical measurement that determines fit, force output, and travel capability in your application. A 15/64" OD extension spring is well-suited for medium-strength designs that require consistent stretch and return.
The 15/64" (0.234375) OD springs we offer come in several combinations of wire diameter, total coils, body length, and initial tension — all affecting how the spring behaves under load.
All our 15/64" OD stock extension springs are manufactured from premium materials including 302 stainless steel (ASTM A 313) and music wire (ASTM A 228), ensuring durability, strength, and resistance to fatigue and corrosion.
