KTC ATS3083, 1/2"Sq. Hub Socket Set For Impact Wrench (3Pcs.)

• This socket set is for loosening front (rear) axle hub nuts and hub bolts with double hexagonal or E-type Torx shapes used in European cars using an impact wrench.
• The sockets feature a diameter and outer circumference that match the hub. They are semi-deep type that do not interfere with the drive shaft threads.
• It employs KTC's unique pin-removal prevention mechanism, the " AMBAC system ". By making one side of the pin hole of the socket a wall and shifting the center of gravity of the pin from the axis of rotation towards the wall, centrifugal force is always applied towards the wall, reliably preventing the pin from popping out and improving safety during operation.

Detailed information

The pin won't fly off due to centrifugal force!
Combined with KTC impact wrench sockets, it ensures safe operation!
Unique pin retention mechanism: AMBAC system.

Impact wrench sockets are secured to the anvil (drive square) with a pin and ring to prevent them from coming off the power tool during use. However, there was a risk of the pin flying out due to centrifugal force. KTC developed a mechanism that reliably prevents the pin from flying out by making one side of the pin hole a wall and shifting the pin's center of gravity away from the axis of rotation towards the wall, so that the centrifugal force is always applied towards the wall. This is the AMBAC system.

AMBAC is　an acronym for Anti -disconnect Mechanism By A vailing of Centrifugal force.
