Internal-External Thread + Key Pins Structure — Revolutionizing Thread Reliability
When assemblies face prolonged vibration, repetitive loading or harsh environments, standard threaded joints often loosen over time.
This key-locking threaded insert is engineered to elevate joint reliability and durability:
Mechanical key-lock design: The insert features both internal and external threads with locking pins driven into the parent material, creating a positive mechanical anchor to prevent rotation and pull-out.
Superior vibration resistance: Tailored for high-vibration or dynamic load environments, it maintains fixed engagement even under sustained motion.
Quick and reliable installation: Standard drill and tap, screw in the insert, tap in the keys — no adhesives or secondary locking devices required.
Versatile substrate compatibility: Works with aluminum, cast iron, steel, stainless steel and even some plastics — ideal for thread repair or reinforcement applications.
Choose this insert to add a robust layer of anti-loosening, vibration-proof reliability into your fastening solution.
