Split insert tensile grips are designed for safe, high-volume production testing of threaded-end, shoulder-end, or button-end machined specimens. Engineered with an operator focus, the split insert style tensile grips are easy to install, offer quick change inserts for standard specimen sizes, and promote efficient static testing of a wide range of metals and alloys. A preferred solution for the testing of high-strength, high-toughness materials that may damage or cause excessive wear to traditional grip arrangements. These grips are designed to comply with ASTM E8, ASTM A370, or ASTM A48, and other international standards, and can be made to custom specifications. A wide range of possible button-end, shank hole, and chamfer / radius dimension options ensures compatibility with a large variety of specimen sizes.

Self-Aligning Tension Grips

The self-aligning tension grips are designed to perform static tensile tests on threaded-end test specimens to various international standards, including ASTM E8, ASTM A370, and ASTM A48. The grips are designed with a double alignment arrangement at each end, which forms a universal joint of movement. This ensures the specimens are loaded in uniaxial tension, and do not require any adjustment during use. A full range of interchangeable grip heads are available for use with specimens of different cross-sectional areas. A safety guard is provided for the shoulder specimen grips to prevent specimens being ejected from the grips where stored energy is released on specimen breakage.

Threaded-End Specimen Holders

The threaded-end specimen holders are designed to perform static tensile tests on threaded-end specimens to various standards, including ASTM E8 and ASTM A370. The specimen holder has threads on each end: one end threads into an adaptor (purchased separately) connecting it to the frame, and the other end having threads to hold the specimen. With a properly aligned crosshead, the threaded-end specimen holders ensure the specimens are loaded in uniaxial tension. Each set contains 2 threaded-end specimen holders. Capacity 267 kN. Temperature Rating: +5°C to +40°C

Shoulder-End and Button-End Specimens Holders and Inserts

The modular design offers a single set of holders and interchangeable split inserts that match industry standard dimensions for performing tensile testing on shoulder-end and button-end specimens. Each set of insert holders requires at least one set of inserts to perform a test.
