47-64 Outer Diameter

47/64" (0.734375) Inch Outer Diameter Standard Extension Springs

Definition of 47/64" Outer Diameter Extension Springs:
A 47/64" (forty-seven sixty-fourths of an inch) outer diameter extension spring has an outer diameter of 0.734375 inches. This spring size is commonly used in heavy-duty applications that require strong pull force, high reliability, and excellent durability. Typical uses include large industrial mechanisms, heavy tools, automotive components, and mechanical systems under frequent tension.

At The Spring Store by Acxess Spring, we provide a wide selection of 47/64" OD extension springs available in various wire diameters, hook styles, body lengths, and load capacities.

Your 47/64" (forty-seven sixty-fourths of an inch) extension spring’s outer diameter is a key factor in determining how the spring performs under load. A 47/64" OD extension spring is ideal for systems that demand high pulling strength and long-term durability, especially in high-stress or repetitive-use environments.

The 47/64" (0.734375) OD extension springs we offer are available in multiple configurations — such as coil count, wire thickness, body length, and hook design — all of which influence the spring’s tension capacity and flexibility.

All of our 47/64" OD extension springs are made from premium materials like 302 stainless steel (ASTM A 313) and music wire (ASTM A 228) for top performance in terms of resilience, spring-back, and corrosion resistance.
