Power Sockets – 6-Point Hexagon – Torsion

The square drive of the Action® torque socket wrench is rounded outwards at the corners. Firstly, this ensures an excellent fit with the drive spindle of the screwdriver. Secondly, it ensures that the torque is transmitted not only at the corners of the impact socket but also along the flanks. This increases the service life of both the impact socket and the drive spindle of the impact wrench. 

Torque Limitation 

A torsional power socket is sometimes also referred to as a “torque socket wrench.” However, this term tends to cause confusion, as it can easily be mistaken for a torque wrench. A torsional power socket differs from ordinary power sockets primarily in its ability to absorb excess torque.

This function is based on the material properties of the tool. A special steel alloy and the diameter of the shaft cause the socket’s shaft to “yield” at a certain tightening torque, converting the force into torsion. This limits the torque output and prevents dangerous overstretching of the bolt.

To prevent damage to the torsion zone caused by high torque when loosening bolts, torsion sockets should only be used in the clockwise direction (tightening).

Instructions for use 

• Replace worn power sockets at the first sign of wear.
• In accordance with EU Directive 2006/42/EC (Machinery Directive) and EN/ISO 11148-6, only power sockets may be used on power tools.
• Never hold rotating parts by hand!
