The surface finish and the appropriate mix of materials ensure that the specimen is held securely in the tensile testing machine.
All jaws are made of hardened, nickel-plated steel (58 HRC) and can be easily assembled and disassembled.
To do this, the 2 mm setscrews with a hexagon socket are loosened and tightened again.
In the case of clamping jaws with a rubber pad, the maximum opening width of the clamping tool is reduced by 2 mm.
Clamping jaws coated with synthetic diamond have a particularly good grip when performing tensile tests on material with a very smooth surface.
This type of coating changes the opening width of the screw grips only slightly.
The wave jaws are suitable for tensile tests on flexible materials.
The V-jaws are suitable for round materials from 2 mm and have a 0.8 mm toothing.
