Stahlwille 7380N/7385N Angle measuring disks No. 7385N

Angle measuring discs for angle-controlled screw tightening, with stationary reading point. Safe reading from any angle due to 2 slanted scales.With unscrewable magnet for attaching a socket wrench with 1/2" square drive.To be used with a tightening tool, e.g. Service MANOSKOP® No. 730N. Since a defined setting torque must first be applied for
angle-controlled screw tightening, a torque wrench whose capacity covers both the setting torque and the tightening force required to achieve the angle of rotation should always be used as the tightening tool. The choice of angle measuring disc - with 1/2" or 3/4" square - depends on the square of the tightening tool. 1/4, for tool holder 9x12 mm
