Screw Grips

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

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

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

• Precise test results combined with high number of cycles thanks to centering aid for insertion of wires and threads.

• High jaws ensure gentle gripping of the specimen, avoiding jaw breaks .

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.

• 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.

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

• The base unit acts as a centering stop for 15mm-wide strip specimens.

• 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

• Large opening widths offer flexibility.
• Adjustable opposing jaws allows eccentric specimen gripping, enabling asymmetrical gripping of specimens.
• A range of jaws ensures optimum matching to test material: Various materials, surface structures and gripping surface sizes are available.
• Jaws can be changed without tools. Easy side insertion into specimen grip and centering and fixing of jaws follow automatically.
• High gripping force is achieved through the axial bearing and gear ratio in the clamping unit.
• Prestressed spring disk induces automatic retightening in smaller areas. Specimens with lower thickness reduction can also be gripped securely over the course of the entire test.
• High temperature resistance (-70 to +250 °C) is ideal for use in temperature chambers.
• Simple handling
• The U-design provides good accessibility to the screw grip and offers ample space for flexible specimen ends

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

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

• Large opening width enables flexibility in use.

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

• Uniform, parallel closing/gripping via precision 4-column guides ensures specimen is held securely.

• No tools required for jaw change; simply slide into grips from side. Jaws are centered and locked into place automatically.
• High temperature resistance (-70 to +250 °C) makes the grips ideal for use in temperature chambers.
• Integrated jaw mountings.

• The clamping distance is symmetrical to the tensile axis. This is advantageous because the specimen is not subject to bending moments.
• Secure gripping is ensured by protruding pins located in the jaws.
• A support grip located in the center of the screw grips facilitates gripping and vertical alignment of the specimen.

• High temperature resistance (-70 to +250 °C) is ideal for use in temperature chambers.
• Integrated jaw mounting.
• An increased closing force is achieved through the axial bearing in the clamping unit.
• Jaws can be changed without tools. Easy side insertion into specimen grip and centering and fixing of jaws follow automatically.
