9-64 Outer Diameter
9/64" (0.140625) Inch Outer Diameter Standard Compression Springs
Definition of 9/64" Outer Diameter Compression Springs:
A 9/64" (nine sixty-fourths of an inch) outer diameter compression spring has an outer diameter of 0.140625 inches. This is a small-sized spring commonly used in compact mechanisms requiring precise, light-load compression. Applications include electronics, small medical devices, pens, battery contacts, and mini mechanical assemblies.
At The Spring Store by Acxess Spring, we carry a range of 9/64" OD compression springs in different wire diameters, spring rates, and lengths to help you achieve performance in minimal space.
How To Measure Your 9/64" Inner Diameter Stock Compression Spring




Your 9/64" (nine sixty-fourths of an inch) compression spring’s outer diameter is essential in tight-space applications where minimal force and high precision are required. A 9/64" OD compression spring is designed to fit snugly in miniature housings and deliver reliable light compression force.
The 9/64" (0.140625) OD compression springs we offer are available in various configurations, including wire size, free length, total coils, and spring rate to meet the strictest design criteria.
All of our 9/64" OD compression springs are manufactured from premium 302 stainless steel (ASTM A 313) or music wire (ASTM A 228), offering excellent fatigue life, elasticity, and corrosion resistance in small-scale applications.
