The threaded bolt grip is used to test metal bolts, rods, and screws. The grips attach onto a testing machine via a 40mm clevis coupling and use a 16mm locking pin. There are two pieces, the first is the carrier which attaches to the machine and the second is the drop-in insert. The insert is tapped and threaded according to customer specifications. This simple design is affordable and easy to expand with larger collections of threaded inserts.
UGC also offers drop-in bolt grips for button-headed samples which are popular in ASTM E8 and other metal tensile tests.
