3-4 Outer Diameter
3/4" (0.75) Inch Outer Diameter Standard Compression Springs
Definition of 3/4" Outer Diameter Compression Springs:
A 3/4" (three fourths of an inch) outer diameter compression spring has an outer diameter of 0.75 inches. This mid-to-large size compression spring is commonly used in mechanical systems requiring moderate to strong compression force and durability. It is ideal for use in tools, industrial devices, automotive systems, and mechanical hardware.
At The Spring Store by Acxess Spring, we stock a broad selection of 3/4" OD compression springs in a range of wire diameters, lengths, spring rates, and total coils to match a wide range of needs.
How To Measure Your 3/4" Inner Diameter Stock Compression Spring




Your 3/4" (three fourths of an inch) compression spring’s outer diameter defines how much force it can handle and where it can be applied. A 3/4" OD compression spring is well-suited for devices needing strong resistance in a compact cylindrical form.
The 3/4" (0.75) OD compression springs available at The Spring Store are offered in multiple configurations — including wire size, free length, total coils, and spring rate — to help you find the perfect match for your performance requirements.
All of our 3/4" OD compression springs are manufactured using high-quality 302 stainless steel (ASTM A 313) or music wire (ASTM A 228) for strength, elasticity, and long-lasting durability.
