Its limitless potential meets various applications of angle-torque measurement

Key Features

Adopting the measurement requirements in JIS B 1084 and ISO 16047 standards, the tester has been developed for testing fasting force of fasteners . It is capable for testing clamp force, tightening torque, thread torque, tightening rotating angle and extension of bolt.

You can also find torque tester, torque wrench tester, torque analyzer, digital torque tester in our website.

  • 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)

The purpose of Slider Kit is to gather common slideshow-like jQuery functionalities (such as news sliders, photos galleries/sliders, carousels, tabs menus)

When tracking mouse movement, you usually need to know the actual position of the mouse pointer. The event object that is passed to the handler contains some information about the mouse coordinates.
