In this video Instron Applications Engineer, Charlie Pryor, discusses how a 3-jaw chuck is a useful accessory to have in the lab for compression, tensile, torsion, rigidity, and tack testing applications. Compatible with Instron MT torsion testers, universal testing machines, and the torsion add-on, the 3-jaw chuck can be used to mount a variety of attachments, including probes, screwdriver bits, custom-made adapters, and can even be used to clamp directly onto specimens.
