Definition of 13/32" Outer Diameter Extension Springs:
A 13/32" (thirteen thirty-seconds of an inch) outer diameter extension spring has an outer diameter of 0.40625 inches. This size is commonly used in applications that require moderate to strong pulling force within compact or confined spaces. These springs are ideal for tools, equipment, appliances, and mechanical devices.
At The Spring Store by Acxess Spring, you can explore a full catalog of 13/32" OD extension springs in various configurations — wire sizes, hook styles, body lengths, and load capacities — ready to ship.
How To Measure Your 13/32" Inner Diameter Stock Extension Spring




Your 13/32" (thirteen thirty-seconds of an inch) extension spring’s outer diameter is a key specification in achieving the right fit and performance in your application. A 13/32" OD extension spring delivers solid pulling strength while maintaining a compact form factor, making it suitable for repetitive motion systems or tension-based mechanisms.
The 13/32" (0.40625) OD extension springs available at Acxess Spring are offered in many configurations — total coils, wire thickness, hook type, and body length — affecting how the spring behaves under load and how far it can safely extend.
All of our 13/32" OD extension springs are made from durable 302 stainless steel (ASTM A 313) or music wire (ASTM A 228), ensuring top-tier resistance to fatigue, corrosion, and high-cycle performance.
