The unique SR dovetail design used to join head and wrench provides an exceptionally strong connection and allows complete interchangeability. The SR system contributes to both operational flexibility and enhancing your return on investment!

To achieve constant torque values when changing heads, exact lever length must be maintained. Virtually all SR heads share a precise distance from end of wrench to center of fastener. This is referred to as a “Common Center Line” and is very difficult to maintain using the cut and weld construction method.

Interchangeable heads with the same centre line may be interchanged among themselves arbitrarily, without needing the torque wrench to be adjusted again.
