Bolt Torque Tension Testing System / Nut Angle Testing System

Bolt torque tension testing system – Automated, Tabletop The product reliability is proportional to the quality of the fastener assembly. Correct application of torque enhances product durability, avoids premature failure, and ensures safety.

Sushma Bolt/Screw Tension & Torque Testing System is designed to verify and validate the torque and clamping force of threaded fasteners and to find its K-factor. The system consists of a rigid test rig with torsion sensors, a control panel, required adapters & fixtures along with the Sushma torsion testing software (optional).

The bolt torque testing equipment evaluates torque tension characteristics of various types of fasteners varying from sizes M2 to M68.
