When the application requires a special head configuration the STA-Series adapters permit fabrication of a custom head specifically meeting the requirements of the application. Each head has the female dovetail connector required to fit SR interchangeable head torque wrenches.

Please note: These adapters should NEVER be used with the Quick Change dovetail. 

Caution When Creating and Using Custom Heads!

When creating custom heads to use with micrometer adjustable torque wrenches (CCM-Series tools) it is critical that the common centerline length be correct or the tool will not apply the indicated torque. When fabricating special heads to use with CCM-Series torque wrenches other than the CCM 300 and the CCM 400, the 1 7/16” common centerline length must be maintained. When fabricating special heads to use with the CCM 300 and CCM 400, a 3 7/8” common centerline length must be maintained.
