Screw action grips provide a very simple and efficient method for holding test specimens in a wide range of applications. The dual-acting design means that jaw faces can be adjusted to accommodate different specimen thicknesses, this ensures that the line of tensile force remains concentric with the grip body. They can be equipped with a selection of interchangeable grip jaw faces in various sizes and choice of surfaces including smooth ground, rubber-coated, and serrated.

Principle of Operation

The 2710-100 Series dual-acting screw design accommodates specimens up to 46 mm (1.8 in) thick and can be offset for irregular or asymmetrical specimens such as lap-shear types and component testing. Screw knobs on either side are knurled to facilitate hand tightening and the higher capacities also feature hex socket screw knobs that accommodate a hex key or torque wrench. Engraved scales on the carriages aid in centering the planes of gripping.
