Beta Tools 642 Series Open Jaw Wrenches for 16mm Torque Bars

If you have to tighten the same size fastener(s) repeatedly in a production-type setting, you can eliminate some torque error and slop by switching to a torque bar with a dedicated solid head. These torque bar heads from Beta Tools fit all Beta torque bars with a 16mm diameter drive (608 or 668 series, sold separately).

The 642 Series open-end (crowfoot) heads are perfect for torquing fasteners where socket access is a problem (including jam nuts).
