These vice grips are used in tension testing on force test stands and material test systems.
Pyramid (crosscut), rubber, wave, or v-jaws are included. A choice of 30 mm, 50 mm, 80 mm and 100 mm widths for the jaws.
The dual screw design accommodates samples up to 30 mm thick. Jaws can also be offset for asymmetrical test specimens. A T-handle is on one side and the other side can be adjusted using a hex key or twisting by hand.
This grip is designed to mount on a standard 5/8" eye end. Adapters are available to accommodate other sizes. This connection type is commonly used on test stands, load cells and force gauges.

Jaw Options
Each grip comes with a pair of jaws. The jaw width chosen should be at minimum the same width as the sample being tested. Jaw width of 30, 50, 80 and 100 mm are available online. If other sizes are needed or you need help deciding on jaws or grips, please contact us.
Adapters to Fit Most Test Stands, Load Cells and Force Gauges
These vice grips have a 5/8" eye end. Chatillon, Lloyd, Mark-10 and many other manufacturers use this same size fitting. Adapters are available for machines using other connection sizes. If you don't see the adapter you need please contact us. Not all of our adapters are online. When contacting please provide the model and manufacturer of your testing equipment.
Jaws can be changed by loosening the three screws on top of the jaw with an Allen wrench.
