Torque adapter 12.0 Nm 1/4 inch hexagon, 1/4 inch square

Turn your ¼ inch bit and a reversible ratchet into your perfect torque tool. The torque value is preset in the adapter and can be clamped between any standard holding tool and a bit. The clicking sound indicates when the torque has been reached. The adapter cannot be overtightened. When loosening the screw, there is no torque release (due to the blocked core shaft), so no additional loosening tool is required (30% higher torque when loosening). The adapter is primarily suitable for manual operation.

The adapters are tested in accordance with DIN EN ISO 6789 (hand-operated torque screwdriving tools) and have a tolerance of ± 10% for at least 20,000 clicks. The torque value should be checked regularly by the user using a torque meter. The adapter functions by means of the ratchet's anti-kickback device, the torque in the socket sleeve. The patented system also consists of a hollow shaft and a damping cylinder. The core shaft is able to move the mobile ratchet. The damping cylinder has a slot so that the spacer sleeve can slide on the core shaft. If the applied torque exceeds the preset torque, the core shaft becomes inactive. This means that when the torque requirement is reached, the continuous tension is no longer increased, including on the bolt to be tightened.
