21/32" (0.65625) Inch Outer Diameter Standard Compression Springs
Definition of 21/32" Outer Diameter Compression Springs:
A 21/32" (twenty-one thirty-seconds of an inch) outer diameter compression spring has an outer diameter of 0.65625 inches. This medium-to-large spring size is commonly used in assemblies requiring consistent force and moderate-to-high load support, such as in tools, mechanical parts, fixtures, or automotive systems.
At The Spring Store by Acxess Spring, we offer a wide range of 21/32" OD compression springs in various configurations, including spring rate, wire diameter, length, and total coils.
How To Measure Your 21/32" Inner Diameter Stock Compression Spring




Your 21/32" (twenty-one thirty-seconds of an inch) compression spring’s outer diameter directly affects its mechanical performance, especially in load capacity and travel. A 21/32" OD compression spring provides excellent reliability for medium-to-heavy-duty uses in mechanical designs.
The 21/32" (0.65625) OD compression springs in our catalog are available in a wide selection of wire sizes, free lengths, total coils, and spring rates to help you fine-tune performance to your specifications.
All our 21/32" OD compression springs are manufactured from high-quality 302 stainless steel (ASTM A 313) or music wire (ASTM A 228), both offering strength, resilience, and corrosion resistance.
