The angle of the jaw faces and the body wedges force the faces inward on the specimen
until the face serrations bite into the specimen. The gripping force increases during a
test as the system applies more tensile force to the specimen.
Open
When you turn the control handles to open the grip, the screw action of the control nut
and body threads move the body toward the test specimen. The movement eliminates
the gripping force on the specimen and allows the four springs to retract the jaw faces
away from the specimen.
