Secure Lock-In • Unshakeable Connection — Key-Locking Thread Insert for Critical Applications

When facing high-stress and high-vibration environments, such as aerospace structures or automated manufacturing systems, traditional threaded fasteners may loosen or fail over time.
This key-locking thread insert (pin-type) solves that by using built-in locking pins that mechanically secure the insert to the base material — guaranteeing an unshakeable joint even under extreme vibration or repeated removal.

  • High Strength & Stability: The locking pin physically prevents rotation or pull-out, delivering robust tensile strength and vibration resistance. 

  • Easy Installation: Requires only standard drilling and tapping — install the insert, hammer in the pins, and you're done. 

  • Material Versatility: Compatible with a variety of base materials, including aluminum alloys, steel, and stainless steel. 

  • Removable & Replaceable: If you need to service or replace, the locking pin can be broken, and the insert safely removed using standard tools. 

  • Cost-Effective & Universal: With high compatibility across different applications, this insert reduces component diversity, simplifies inventory, and lowers procurement complexity. 

Recommended Industries:

  • Aerospace (airframe, composite materials)

  • Automation & Industrial Machinery (robotic lines, assembly equipment)

  • Automotive & Transportation (chassis, structures)

  • Marine & Shipbuilding (high vibration, corrosion resistance)

  • Precision Machinery (labs, medical instruments, test rigs)

By choosing this key-locking insert, engineers and manufacturers can ensure long-term, reliable fastening in demanding applications — turning high-vibration risks into secure, maintenance-friendly joints.
