TT Dial Torque Screwdriver

+ Enlarge Picture


A dial indicating torque screwdriver is designed for torque evaluation and torque verification. It is a low cost tool that can utilized for torque auditing or R & D torque testing and product evaluation. It can be used to monitor torque as it increases or decreases or display peak torque applied. This tool can be used in two ways, it can either be set in track mode so it can constantly track the applied torque or set in memory mode, which is done by withdrawing the slider and resetting the bezel ring to zero before using. This tracks the applied torque as before, but leaves the memory pointer at the maximum torque position.

The preferred and certified ranges of these tools is in accordance with the requirements of ISO 6789 (+/- 6% of indicated reading).
