TK Wire Threaded inserts – also known as screw or helical threaded inserts – quickly repair or reinforce tapped holes in soft metals. Made from 18-8 stainless steel wire, inserts provide strong internal threads that are corrosion resistant and withstand temperatures to 800°F.
The wire is formed into a diamond pattern and then wound into a spring. Before being installed, the insert diameter is larger than the tapped hole. The insert diameter is reduced during installation, allowing the insert to thread into the hole. Once properly installed, the radial pressure of the released insert holds the insert firmly in place.
TK wire threaded inserts are available from stock in either free running or screw locking types, which come in five standard lengths and in various pitches and thread types, including metric, UNF, UNC, and British Standard.
