Versatile torque limiters allow conventional hand and power tools to be easily converted into torque tools. With an accurate process control assured by eliminating under and over tightening. With its very flexible design the tool can be used in a wide range of applications. The Rotary Torque Units are designed to be used 'inline' to limit torque. Ideal for use in both manual and non impact power driven applications. The new " Hex Drive RTU Models are the ideal solution for high precision tightening applications where the speed of a powered tool is needed. Mechanism slips free when preset torque is reached, eliminating over tightening. Bi-directional torque application. Robust construction with corrosion resistant finish. Repeatability +/- 6% of set torque. ISO 6789 Classification 2F
