MIL SPEC Compression (MS24585)

Available for Immediate Delivery from Stock

The MS24585-56 is a military specification compression spring from the MIL SPEC Compression (MS24585) Series, designed to meet stringent defense and aerospace standards for critical applications. This precision spring features a 0.18-inch outside diameter (4.57 mm) and a 0.81-inch free length (20.57 mm), providing reliable compression performance in military and aerospace systems where consistent operation under extreme conditions is mandatory. Manufactured from Music Wire with a 0.022-inch wire diameter (0.56 mm), the spring delivers a spring rate of 7.7 lb/inch (1.349 N/mm) through its 11.5 active coils out of 13.5 total coils, ensuring predictable force characteristics required by military specifications. With Squared and Ground for optimal load distribution and precise seating, the spring compresses to a solid height of 0.297 inches (7.54 mm) while supporting a maximum load of 3.974 pounds (17.68 N) at full compression. MIL-SPEC springs are essential for defense contractors, aerospace manufacturers, and government applications where compliance with military standards and proven reliability are non-negotiable requirements.
