S/R Interchangeable Head System
Strength and Flexibility Combined!

The S/R Interchangeable Head System includes over 140 interchangeable heads with our unique dovetail design!

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 form 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 both operational flexibility and enhancing your return on investment!

We also offer adapters for round plug type heads so those with an existing inventory of them can obtain a smooth upgrade transition path to S/R interchangeable head wrenches. We also offer here straight and angled extensions for unusual applications, adapters to permit interchangeable head use with indicating torque wrenches (such as our flat beam tools), and adapters that enable you to customize your own heads for unique applications.

Whether you are using a unique fastener, have limited access, face multiple fastener or connection types, or some other torque application challenge, the S/R System of Interchangeable Heads and Interchangeable Head Torque Wrenches has the answer!
