The mouth width of AH adjustable open end heads can be adjusted, so there’s no need to keep SH interchangeable heads on hand for each separate mouth width. This is especially convenient when working with hydro-pneumatic piping, for maintenance, and for torque control with inch-standard bolts.

* Note 1: Use at no more than AH torque tolerance (Tmax) and at no more than the torque wrench’s maximum torque.
* Note 2: Use the AH with a click-type torque wrench for tightening.
