Product Description

Screw Connections Testing

The main element of the unit is a slotted, elastically deformable steel block. By tightening the bolt joint, the slotted area is deformed, thereby generating an axial tension force in the bolt. The resulting deformation is recorded by a mechanical dial gauge, and is directly related to the bolt tension force generated.

Learning Objectives And Experiments

• Axial tension force in a bolt joint dependent on the tightening torque or the elastic deformation of a slotted block
• Measurement Of The Breakaway Torque, Including For Different Fitting Situations Of The Bolt Joint
• Measurement of thread friction and overall friction

Features

• Correlation between tightening torque and tension force on standardised bolts
• Breakaway torque of a bolt joint
