The Open End Slim Profile Head “OE SPH” is used for torque wrenches that use interchangeable heads. This series presents stronger heads with consistent dimensions.
The common centerline was kept consistent (since it is vital to eliminating assembly variables) thanks to accurate torque values critical to creating compliant hydraulic connections.
We’ve refined the Dovetail a few times since then, but the basic concept is as strong today as it was back then. It is still the most effective approach to delivering maximum torque application using torque wrenches with interchangeable heads.
