Preset Types torque wrenches are for use in a production environment where they will be set and then dedicated to a particular application. There is no scale, and so must be set against a torque testing device such as a Professional Torque Tester.
Torque Handles are available covering a range of 8 to 300 N•m and can be supplied with 16mm spigot, 9 x 12mm or 14 x 18mm rectangular type (dependant on torque capacity).
