ISO 898-1 bolts and screw wedge loading tensile testing machine

bolts wedge loading tensile testing machine,screw wedge loading tensile testing machine

1.introduction
This bolts and screws wedge loading tensile testing machine can determine the tensile strength on finished bolts and screws, the integrity of the transition section between the head and the unthreaded shank or the thread.

Wedge loading of finished bolts and screws, this testing device is rigid to ensure that bending occurs on the transition section between the head and the unthreaded shank or the thread.
2.test  method
