Stainless Steel 304 Standard Size M12 M16 M20 Wire Screw Thread Insert
Information
There are two types of wire thread inserts Shank thread inserts. Standard or "free running" shank inserts provide smooth free running threads, while "screw lock" shank inserts provide a self-locking torque coil on the male member through a series of "chords" on one or more inserts.
Free-rotating shank threaded inserts are larger in diameter than the threaded holes in which they are installed. During assembly operations, the torque applied to the tang reduces the diameter of the lead coil and causes it to enter the threads. When torque or rotation ceases, the coil expands like a spring, permanently securing the insert to the threaded hole.
Screw Locking Shank Threaded Inserts provide a unique elastic internal locking thread that grips the bolt and prevents it from loosening under vibration or shock. Screw locking inserts allow repeated assembly and disassembly without loosening the grip on the screw, even in tough metals such as cast iron, alloy steel, titanium, etc.
