Function description

This 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.

The clamping unit can be adjusted in 1 mm increments using a tool to change the gripping range.

The opposing jaw is different depending on type:
Step-by-step adjustable: securely mounted, can be adjusted in 1 mm increments with a tool
Stepless and step-by-step adjustable: adjustable via lead screw, additionally adjustable in 1 mm increments with a tool

The specimen grip can be mounted at 45° and 90°.

The opposing jaw of the screw grip that can be adjusted step by step is permanently mounted, but the gripping range can be adjusted with a tool in 1-mm stages. The specimen grips are factory set to a specimen thickness of 0 mm.

You can set the stepless grip insert of the stepless and step-by-step adjustable screw grip to half specimen thickness. The closing force is generated via the gripping wheel. The opening width can be adjusted from 0 to 10 mm.

Advantages and features

The lightweight design of the grips allows extensive use to be made of the load cell measurement range.

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.

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

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

Difficult-to-access components and short specimens can easily be reached by hand thanks to the projecting grips.
