3-8 Outer Diameter

3/8" (0.375) Inch Outer Diameter Standard Compression Springs

Definition of 3/8" Outer Diameter Compression Springs:
A 3/8" (three eighths of an inch) outer diameter compression spring has an outer diameter of 0.375 inches. This size offers a balanced solution for small-to-medium scale projects requiring moderate compression force. These springs are often used in electrical components, small engines, control mechanisms, and precision tools.

At The Spring Store by Acxess Spring, we stock a variety of 3/8" OD compression springs in different wire diameters, coil counts, lengths, and load ratings for a wide range of applications.

Your 3/8" (three eighths of an inch) compression spring’s outer diameter impacts how it fits and performs in mid-size mechanical systems. A 3/8" OD compression spring is ideal for designs requiring compact form with effective load-bearing capabilities.

The 3/8" (0.375) OD compression springs in our inventory are available in many combinations — wire diameters, coil counts, free lengths, and compression rates — making it easy to find the exact match for your specifications.

All of our 3/8" OD compression springs are produced from 302 stainless steel (ASTM A 313) or music wire (ASTM A 228) for long-lasting durability, excellent tension, and corrosion resistance.
