1-2 Outer Diameter
1/2" (0.5) Inch Outer Diameter Standard Compression Springs
Definition of 1/2" Outer Diameter Compression Springs:
A 1/2" (one half of an inch) outer diameter compression spring has an outer diameter of 0.5 inches. This medium-sized compression spring is widely used in mechanical devices, automotive parts, control systems, and consumer electronics that require moderate force and durability in a compact size.
At The Spring Store by Acxess Spring, we offer a large selection of 1/2" OD compression springs in different lengths, wire diameters, total coils, and spring rates to suit a variety of applications.
How To Measure Your 1/2" Inner Diameter Stock Compression Spring




Your 1/2" (one half of an inch) compression spring’s outer diameter is a defining factor for space, load, and mechanical behavior. A 1/2" OD compression spring is ideal for applications requiring balanced force, compact size, and resistance to fatigue.
The 1/2" (0.5) OD compression springs in our inventory come in multiple variations — from wire thickness and total coil count to free position and compression rate — to match specific performance demands.
All of our 1/2" OD compression springs are made from high-quality 302 stainless steel (ASTM A 313) or music wire (ASTM A 228) to provide strength, elasticity, and corrosion resistance for extended use.
