Screw grips up to 500 N

The ideal specimen grip for thinner specimens

The screw grip is a one-sided closing specimen grip. A lead screw is used to open and close the grips, as well as apply gripping force before the test.

Advantages & features

General

Adjustable opposing jaw for fast, easy testing, including joined (asymmetrical) specimens

If the test configuration changes the jaws can be changed quickly and easily - no tools required. The jaws are centered automatically.

The use of ball bearings enables secure gripping of the specimen even at low operating forces.

Large opening width enables flexibility in use.

Reliable specimen gripping guaranteed even with varying applications. Large range of jaws allows optimum matching of the grips to your application.

Even specimens prone to shrinkage are securely held via automatic re-tightening by means of a laminated plate spring

The grips are easy to operate in a temperature chamber and reach the test temperature quickly thanks to their very low mass.

Precise test results combined with high number of cycles achieved through centric insertion of specimen using easily adjustable centering stop.

Ergonomic, open design for fast, easy specimen insertion and clamping

The opening width is a result of using jaws with 4 mm jaw thickness and an outwardly adjusted jaw and opposing jaw. If only the opposing jaw is outwardly adjusted (adjustment range up to 9 mm), the maximum opening width is 14 mm.
The ambient temperature may be limited by a smaller jaw temperature range.
