Screw Grips

The screw grip is a one-sided closing specimen grip. A lead screw is used to open and close the grips, as well as apply gripping force before the test.

Advantages of the screw grip

  • The gripping force is dependent on the tightening torque, which is applied by the operator
  • The grips are very easy to operate
  • Large opening widths for flexibility in use
  • Due to the most commonly used U-shape design of the screw grips, these are easily accessible
  • Simple design principle enables standard version to be resistant to high temperatures
  • Depending on the type, these grips have an axial bearing in the gripping unit for increased gripping forces
  • Many screw grips feature free adjustment of both jaws, allowing asymmetrical specimens to be tested
