The military standards for Keenserts are designed to ensure their reliability and performance in demanding applications. Here are the key military specifications associated with Keenserts:
MIL-I-45914A: This is a general specification for key-locked, screw thread inserts. It covers inserts that have integrated locking keys to prevent rotation when installed in tapped holes. These inserts are known for their high resistance to torque-out and pullout forces. The keys in each insert are driven through the threads of the parent material, mechanically locking the insert into place. This specification ensures that Keenserts can withstand torsion and vibration without rotating .
MS51830E: This specification is for miniature and lightweight key-locked, screw-thread inserts. It emphasizes the small size and reduced weight of the inserts while maintaining their locking capabilities. These inserts are particularly useful in applications where weight is a critical factor, such as in aerospace .
MS51831: This covers a range of key-locked, screw-thread inserts in various sizes and materials. It includes specifications for different series such as KN, KNC, KNL, and KNCL, which are used in stainless steel, A286, and 4140 alloy materials. These inserts are designed for high resistance to torque-out and pullout, making them suitable for high-stress environments .
MS51832B: This is for extra heavy-duty key-locked, screw-thread inserts. It specifies inserts that can handle even greater loads and stresses, making them ideal for the most demanding military applications .
These standards ensure that Keenserts meet the rigorous requirements of military applications, providing reliable thread repair and reinforcement solutions.
