Sturtevant Richmont HD series

Common Centre Line 36.5 mm

Fixed hex drive interchangeable head with 1 7/16" center line

Hex drive interchangeable head with Sturtevant Richmont dovetail connector. Ideal for use when an internal hex drive fastener is to be tightened. Body 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.

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.
