Digital Torque Tension Test Machine for Fasteners

Torque-tension bench that tightens a bolt while measuring torque and clamp force simultaneously to find the nut factor. Used by fastener coaters, automotive assemblers and joint design engineers.

Specification

A bolt is tightened through a load washer sensor with an inline torque transducer so that torque, tension and angle are logged together. The coefficient of friction on threads and under the head is calculated for coated and lubricated fasteners.

Features

• Inline rotary torque and angle transducer
• Washer load cell for direct clamp force measurement
• Servo motor tightening drive with speed control
• Automatic calculation of K factor and friction values
• Interchangeable bolt and nut holders
