Thread Locking Insert: 1/4-28 Internal Thread, 3/8-16 External Thread, UNF, 3/8" OAL, Self-Lock Wall MPN:319-428

Thread locking inserts are small metal devices designed to secure fasteners in place, preventing loosening or unwanted movement due to vibration or mechanical stress. The combination of an internal thread of 1/4-28 and external thread of 3/8-16 allows for versatility in terms of compatibility with various screw types and applications. Made from heat-treated high-strength steel, the insert is resistant to harsh environments and provides exceptional durability. Its UNF designation indicates that it's suitable for use on machine elements such as studs or bolts subjected to heavy loads. With an overall length of 3/8, this thread locking insert ensures easy installation into a pre-tapped hole, allowing fastening personnel to securely lock nuts or other fasteners in place without having to apply additional torque once set - reducing the risk of hardware failure during operation. Overall, these inserts are essential tools for manufacturers or mechanics looking for reliable solutions in maintaining tightened fasteners across diverse industrial applications including aerospace and automotive industries where precision and safety are critical.
