• For particularly high loads, e.g. stainless steel bolted joints
• Full use of the open-ended spanner in combination with standard ratchets or torque wrenches with fixed square

Applications

Manual screwdriving on heavily loaded imperial fasteners with size 2 1/8", for example stainless steel bolted joints, with standard ratchets or torque wrenches with fixed 1/2 inch square. On a torque wrench the crowfoot extends the lever arm, which has to be taken into account when setting the torque.
