Tensile Testing Grips
Tensile grips are used for uni-axial material testing where a sample is pulled apart from two ends. There are many variations of tensile grips for universal testing machines based on the force capacity of the procedure and the specific type of material and geometry. Many of these fixtures can use different types of inserts which can help to secure the sample. Selecting the right combination of grip and jaw inserts is critical to the success of any tensile testing applicatio...

Compression Fixtures
Compression Jigs and Fixtures are the most varied type of grip. Universal Grip has an extensive offering of compression, bend, puncture, and shear fixtures as well as food testing fixtures for texture profile analysis. These fixtures attach onto a Universal Testing Machine using a clevis style adapter and locking pin....

Accessories
Tensile and Compression testing machines can use many different types of accessories depending on the type of test involved. All of these accessories involve measurement, sensing, and data acquisition. Advanced testing requires the use of these instruments to acquire very accurate data. For instance, ASTM D790 recommends the use of a deflectometer to accurately measure the deflection or bend of the sample. Other tests, such as ASTM D638, may require an extensometer for strain meas...

ASTM Specific Grips
Many ASTM test methods require specialized fixtures to ensure accurate and compliant results. There are hundreds of ASTM-specific grips and test fixtures designed for a wide range of materials and procedures. While most are used with a universal testing machine (UTM), some are designed as standalone devices for niche testing setups. Examples of ASTM-specific fixtures include the climbing drum peel test, coefficient of friction (COF) test, various shear test fixtures, and the widely used 90-degr...
