Interchangeable Heads

Why Our Customers Say the S/R System is the World’s Best

Virtually all interchangeable heads on these pag-es are made as a single piece from alloy steel. This construction method provides strength and durability rarely attained by the more common cut and weld method. In addition, to achieve con-stant torque values when changing heads, ex-act lever length must be maintained. S/R heads share a precise distance from end of wrench to center of fastener. This is referred to as a Common Centerline and is very difficult to main-tain when using the welded construction method.

The unique dovetail design used to join head and wrench provides exceptionally strong con-nection and allows complete interchange-ability. Competing manufacturers find it necessary to in-crease the size of the mating connection at high-er torque values, creating duplication of wrench-es and heads while losing interchangeability.

When fabricating special heads to be used with CCM torque handles other than Model CCM 300 and CCM 400,

the 17⁄16 in. dimension must be maintained between the inside of the attachment block and the centerline of

the wrench head. Model CCM 300 and CCM 400 are calibrated to 37⁄8 in. common centerline.

• Can be used to convert most round style heads to a female dovetail for use on all S/R LTC series wrenches. Torque values should be set with the adapter and head attached to the wrench.• Because of the variation in the length of the round plug type heads it is not recommended that this adapter be used with CCM micrometer adjustable wrenches.

What is Common Center Line?

The centerline is the distance between the head end of the wrench and the center of the fastener. When that distance changes, the wrench output changes and no longer matches the scale or is in sync with the calibration formula.

Several factors impact common center line length. Extensions and adapters are a significant factor causes wrenches to be recalibrated for the different centerline length. Smaller unintended differences also cause a change in wrench output.

The interchangeable heads produced by the cut and weld method also change torque output. For more information go to: www.youtube.com/watch?v=YESc2JdXQn4

Here is an example of two click wrenches, set to identical settings. If they had the same head length the output would be the same. But, one wrench has an extended head length and that increases the over all lever length. That change in lever length changes the output of the wrench. When a wrench is calibrated with one head length and a different head length is used during torque applications, the wrench output is different. The difference can be found by plugging in the actual measurements of Lever Length (L) and Force (F).
