Why Turn-of-Nut Wrenches?
Installing hex-head bolts has never been easier and using our turn of nut wrenches will drastically improve productivity –
- No more guessing the rotation – the tool automatically tightens the bolt assembly to the preset rotation every time
- Electric and light-weight– no compressor or heavy air hoses required
- Less fatigue – the installation torque is absorbed by the tool’s reaction arm, not the worker
- No jobsite calibration required – Unlike torque-based installation methods, the turn of nut method is unaffected by changes in bolt diameter and torque. This means a lot less Skidmore testing and a lot less confusion for the installers.
- Compliant with International Standards – GWY’s TN-series wrenches are designed specifically for the “Turn of Nut” installation method found in most international standards, including AASHTO, AISC, RCSC, CSA & CISC
