It employs the AMBAC (Anti-disconnect Mechanism By Availing of Centrifugal force) system (PAT.) to prevent pin removal. About the AMBAC (Anti-disconnect Mechanism By Availing of Centrifugal force) system: The AMBAC system PAT. is a pin removal prevention mechanism for impact wrench sockets and accessories developed by KTC. With the conventional pin and ring fixing method, there was a possibility that the pin would pop out due to the centrifugal force generated when the socket rotates. KTC's conventional products prevented the pin from popping out by shortening the pin to reduce the centrifugal force, but the drawback was that it was more difficult to attach and detach the ring than conventional products because two protrusions were provided inside the ring to prevent the short pin from moving. KTC's AMBAC system has put into practical use the idea of utilizing the centrifugal force, which was the cause of the pin popping out, to prevent it from popping out. By making one side of the pin hole for preventing detachment provided in the socket a wall, and shifting the center of gravity of the pin from the rotation axis of the socket to the wall side, the centrifugal force generated during rotation always acts on the wall side, making it possible to reliably prevent the pin from popping out due to centrifugal force. AMBAC (Anti-disconnect Mechanism By Availing of Centrifugal force) is an acronym for Anti-disconnect Mechanism By Availing of Centrifugal force. This is a KTC-made 25.4sq. impact wrench wheel nut combination socket from a top-class tool brand, offered at a bargain price. Safe and advantageous anonymous shipping is free.
