Bolt Mounting and Torque Control Services
It covers the proper torque of bolted production of any diameter according to the EN 1090-2 standard or checking the degree of torque.

Control principle; It is based on the control process from the nut by placing a mark on the nut part of the tightened bolts, the base material and the nut, and adjusting the torque meter to the desired torque values (EN 1090-1 or Customer Specification).

If the angle between the marks is less than 30°, the torque is within the acceptance values. If it is between 30° and 45°, 2 more bolts from the same group should be checked. If an angle greater than 45° is detected, the bolt is changed and 2 more bolts from the same group should be checked.
