Universal testing machine grips are critical accessories designed to securely hold various specimens during tension, compression, bending, shear and other mechanical property tests. They come in diverse types to match different sample materials and shapes, including wedge grips for metals, pneumatic grips for plastics and films, vice grips for rigid components, and special grips for wires, ropes, plates or irregular parts. Made of high-strength alloy steel with wear-resistant surfaces, these grips ensure stable clamping without damaging specimens, guarantee accurate test data, and adapt to multiple international testing standards.
