Torsion grips are designed to transmit torsional forces to the specimen and usually employ either a collet or socket-style gripping arrangement. Whereas, axial torsional grips are used in conjunction with systems able to apply both torsional and axial loads to a specimen simultaneously.
These universal drill-type chuck grips can be used to hold round, hex or triangular specimens. The standard sets are available in both a keyless and keyed style that can hold a range of specimen sizes.
Two standard sets of Collet Style grips are available: a small collet grip set for smaller specimens and a large collet grip set for larger specimens. Both sets are double angle style.
