CHARACTERISTICS

This machine is for measuring the tightening force of bolts in accordance to JIS B 1084 testing requirements.

Tightening Clamping Force (Ff), Tightening Torque (Tf), Bolt Threaded-portion Torque (Ts), Tightening Rotation Angle and Extension can be measured.

Testing speed of 30RPM can also be set as per ISO 16047 requirements.

 Rotation Angle vs Torque Axial Force graph, Torque vs Axial Force graph, Extension vs Axial Force graph, Extension vs Torque graph can be obtain in one single test.

Measurement of bolt “Reverse Movement Prevention” specified by JASO F 106-96 is also possible.

 As the machine is linked to a personal computer, test graphs can be printed instantly via built-in printer.

Changing and saving of test conditions and data can be perform easily.

Test data can also be exported to spreadsheet such as Microsoft Excel for customization.
