These 'Industrial' push-through ratchets are robustly engineered for strength and durability. They also allow the wrench to be used for torque control in both the clockwise and anti-clockwise directions. These ratchets are available with models to cover from 1 to 400 N·m.
Production 'P' Types 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 Norbar's 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).
