This precision spring features a 0.65-inch outside diameter (16.51 mm) with 0.54-inch loop inside diameter (13.72 mm) and extends from a free length of 2.5 inch (63.5 mm) to a maximum extended length of 5.98 inch (151.89 mm), providing reliable extension performance in military and aerospace systems where consistent operation under extreme conditions is mandatory. Manufactured from Stainless Steel with a 0.055-inch wire diameter (1.4 mm), the spring delivers a spring rate of 2.199 lb/inch (0.385 N/mm) through its 24.5 total coils with an initial tension of 0.75 lb (3.336 N) ensuring predictable force characteristics required by military specifications. With Inline loop positions for optimal load distribution and precise attachment, the spring supports a maximum load of 8.413 lb (37.423 N) at full extension with a body length of 1.403 inch (35.64 mm). This MIL-SPEC spring is essential for defense contractors, aerospace manufacturers, and government applications where compliance with military standards and proven reliability are non-negotiable requirements. Learn about the MIL-SPEC Springs Series - MS24586These products are part of the United States Defense Standard. They are used to help achieve standardization objectives set by the U.S. Department of Defense. This series is also commonly known interchangeably as "military standards", "MIL-SPEC", "MIL-STD" or "MilSpecs." These high precision designs meet stringent technical requirements and are used in a multitude of Military and Aerospace applications, both defense and non-defense related. MIL-SPEC springs are increasingly specified by other non-Defense government organizations, technical organizations, and highly regulated industries. The MIL-SPEC standard for extension springs for loads below 30 lbs. is AS24586; this was formerly MS24586. The MIL-SPEC standard for compression springs for loads below 20 lbs. is AS24585; this standard was formerly MS24585 are also available from stock and ready to ship.
