Free running thread inserts are ideal for thread repair and thread reinforcement Features Greater in diameter than the tapped hole. The diameter of the leading coil reduces due to the torque applied to the tang during assembly to allow it to enter the tapped thread The coils then expands with a spring-like action anchoring the insert permanently in place against the tapped hole. The helical insert automatically adjusts itself, radially and axially, to any expansion or contraction of the parent material. No staking, locking, swaging, keying, nor interference fit is required to retain helical thread inserts Eliminates stress concentration in parent material.​ Available in both, metric and inch series ​​M1.5 to M30 UNC: 2-56 to 1" BSW: 3/16 to 1" UNF: 6-40 to 1" Fine pitch inserts available BSP and NPT available on request
