Self-tightening wedge grips. Wedges remain stationary when applying initial gripping force on the sample via the handwheel, so avoiding excessive compression of the sample prior to test. Grips are supplied with cross-hatched jaw faces for gripping flat samples. Optional V profile wedges are available for gripping round sections up to 15mm (6/10in).

 

The wedge style tensile grip is used on ST series materials testing machines.
