1-8 Outer Diameter

1/8" (0.125) Inch Outer Diameter Standard Extension Springs

Definition of 1/8" Outer Diameter Extension Springs:
A 1/8" (one eighth of an inch) outer diameter extension spring has an outer diameter of 0.125 inches and is typically used in light-duty tension applications such as electronics, miniature devices, and precision tools. These springs offer a balance between compact size and functional strength.

The Spring Store by Acxess Spring offers a wide inventory of in-stock 1/8" OD extension springs with multiple wire diameters, body lengths, and initial tension levels to fit your design needs.

Your 1/8" (one eighth of an inch) extension spring’s outer diameter is a critical parameter in determining how much force it can handle and whether it fits your assembly. Small variations in this dimension can significantly affect performance, especially in precision assemblies or electronic enclosures.

Our 1/8" (0.125) OD extension springs are available with various wire thicknesses, lengths, and hook styles. The wire diameter and number of coils influence how much load the spring can carry and how far it can stretch under tension.

All of our 1/8" OD stock extension springs are manufactured using high-quality materials like 302 stainless steel (ASTM A 313) and music wire (ASTM A 228) to ensure longevity, strength, and resistance to environmental wear.
