Product Description
The MS21250-05016 Steel Shear Bolt is crafted to meet the stringent requirements of the MS21250 military standard, ensuring uncompromising strength, precision, and durability. Built from high-strength alloy steel (options include E4340, 8740, and 4140), this bolt is optimized for performance under extreme shear stress, making it a reliable choice in applications where failure is not an option. The MS21250-05016 shear bolt is cadmium-plated with a chromate coating, giving it robust protection against corrosion, even in harsh environmental conditions. Its right-hand, 24-thread-per-inch UNF (Unified National Fine) thread profile ensures a strong, stable connection, while the bolt’s 12-point head enables easy external wrenching in tight or challenging installation environments.
This shear bolt is specifically designed for high-stress applications in aerospace and defense, where shear forces are at their peak. Its design is tailored to provide critical support and maintain structural integrity, especially in military and aerospace assemblies that are subjected to intense pressure and stress cycling. Each bolt is certified to withstand a minimum tensile strength of 180,000 psi, ensuring durability across long operational lifetimes.
