Interchangeable Heads

Why the S/R Interchangeable Head System is the World's Best

Virtually all S/R interchangeable heads are cast as a single piece from alloy steel. The manufacturing method provides strength and durability rarely attained by the more common “cut and weld” method. To achieve constant torque values when changing heads, exact lever length must be maintained. Virtually all S/R 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.

The unique S/R dovetail design used to join head and wrench provides an exceptionally strong connection and allows complete interchangeability. Competing manufacturers find it necessary to increase the size of the mating connection at higher torque values, creating duplication of wrenches and heads while losing interchangeability.

The S/R system avoids this needless increase in purchase and ownership costs, contributing to operational flexibility and enhancing your return on investment!
