Page 14: Description
Chapter: Introduction Description Components The major grip components are the body, control mechanism, and jaw faces. Body The machined alloy-steel body has a vertical center bore with an integral threaded stud extending away from the body. A control nut threads on the stud and a spindle passes through the bore. -
Page 15: Functional
When you turn the control handles to open the grip, the screw action of the control nut moves the body toward the test specimen. The slide plate, under tension from the spring, applies a force to the grip jaw pins to move the grip jaws away from the specimen.

Page 26: Checklist
Chapter: Operation The force you use to turn the control nut handle determines the initial gripping pressure on the specimen. The tensile load on the specimen determines the gripping force during the test. Caution Do not exceed the maximum load rating of any load string component. Exceeding the maximum load rating of a component will damage it. -
