NST Bolt & Nut Tester

NST Series of BOLT & NUT TESTER
NST-500Nm
CHARACTERISTICS
  • This machine is for measuring the tightening torque (T), tightening clamping force (F) & thread torque (Tth) of bolts in accordance to JIS B 1084 testing requirements.
  • 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.
  • Test Items :-
    • Tightening Clamping Force (F)
