Sturtevant Richmont BH dovetail head

Common Centre Line 1 7/16 inch (~36.5 mm)

Interchangeable Box Head for Dovetail Torque Wrenches

Box head interchangeable head with Sturtevant Richmont dovetail connector. 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. BH box heads are ideal, when:

A socket cannot be used,
The entire hex of the fastener or fitting can be engaged,
A high level of head strength (torque level) is needed.

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 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.

12-point force transmission
SR dovetail connector with outstanding rigidity and wear resistance
Common centre line 1 7/16 inch (~36.5 mm)
