Pneumatic Side Action Tensile Grips
2712-04x Series
Instron’s pneumatic side-action grips provide a high-performance, repeatable, and safe gripping solution for a broad spectrum of materials — from fine wires, fibers, textiles and foils to plastics, elastomers and components — via air-actuated clamping that maintains constant force even as specimens deform. With quick, tool-free jaw face changes, optional alignment and centering devices, adjustable opening and flow control, and integrated safety features (e.g. jaw face shields), these grips are engineered for throughput and reproducibility operator protection in tensile testing applications.

Screw Side Action Tensile Grips
2710-100 Series
The Instron screw side-action tensile grips are precision mechanical grips engineered for tensile testing across a broad spectrum of specimen materials (e.g. metals, plastics, textiles, thin foils) and geometries. Their dual-acting screw mechanism delivers concentric clamping and allows for adjustments to accommodate varying specimen thicknesses or unique components — ensuring reliable load alignment. With quick, tool-free jaw face changes and a wide assortment of interchangeable jaw face types (smooth-ground, serrated, rubber-coated, etc.), these grips offer flexibility in test setup.

Mechanical Wedge Action Grips
2716 Series
The Instron mechanical wedge action grips are durable tensile grips designed to automatically increase clamping force as test loads rise, maintaining fixed jaw positions and preventing slippage. Their open-front, moving-body design allows easy specimen insertion while ensuring consistent gauge length and minimal compressive force during clamping, making them a versatile gripping solution and particularly suitable for testing high-strength materials such as metals and composites.

Advanced Hydraulic Wedge Action Grips
2742 and 2743 Series
The Instron advanced hydraulic wedge action grips deliver controlled, constant gripping force using an external hydraulic supply across static and dynamic testing. They support capacities up to 600 kN (static) and 500 kN (dynamic), with interchangeable jaw faces for round or flat specimens. The design ensures jaw face positions remain fixed during gripping (eliminating preload), compensates for changes in specimen thickness, and is ideally suited for use with metals, composites, and plastics.
