Pneumatic Side Action Grips
Our most popular tensile grip and installed on more than half of all Instron universal testing machines. These grips are easy to use, extremely versatile, and efficient for high volume testing. Up to 10kN force capacity.
Wedge Action Tensile Grips
A classic, simple, and robust tensile grip design; manual wedge action grips are perfect for metals, composites, and plastic. Designed for easy specimen loading, alignment, and positioning. Up to 150kN force capacity.
Screw Side Action Tensile Grips
Screw action grips provide a very simple and efficient method for holding test specimens and are most commonly used for biomedical, plastic film, electronic, and adhesive applications. Up to 10kN force capacity.
Advanced Hydraulic Wedge Action Tensile Grips – Static & Dynamic
The best grips available for most metal and composite tensile testing applications. A hydraulic grip pump is required if installing these on an electromechanical system. Up to 500kN force capacity.
Hydraulic Side Action Tensile Grips
Hydraulic side-acting DuraSync™ high capacity grips deliver enhanced gripping performance, usability, and operator safety over traditional grip designs. Up to 2,000kN force capacity.
Webbing Tensile Grips
Perfect for texile webbing, cargo straps, and seat belt material. Due to the the diversity of materials and widths, most of the grips we supply are custom made for your application.
Pneumatic Wedge Action Tensile Grips – Static & Dynamic
Designed for ElectroPuls™ test instruments, these pneumatic wedge action grips are suitable for tension, compression, torsion, and reverse-stress testing on a wide range of specimens and materials.
Precision Mechanical Wedge Action Grips
Tensile grips for composites and metal that provides accurate and repeatable specimen alignment capable of meeting the alignment requirements of Nadcap AC7122-1 and AC7101. 100kN and 250kN models available.
High Capacity Wedge Action Tensile Grips
Manual wedge grips are designed to provide a high-capacity gripping solution without the need for pneumatic or hydraulic actuation. 250kN force capacity.
Threaded-End and Button-End Grip Bodies
Split insert tensile grips are designed for safe, high-volume testing of shoulder-end or button-head machined specimens. Designed per ASTM E8, ASTM A370, ASTM A48 and GOST 1497 (Type III specimen).
Microelectronic Tensile Grips
A variety of tensile grips suitable for performing tensile tests on a wide range of microelectronic components and assemblies including leads, wires, and irregularly-shaped products.
O-Ring Tensile Grips
The tensile grip designed for ASTM D1414. Designed for testing elastomeric rings, these fixtures avoid local stress concentrations by using a spindle that is rotated by the testing system's moving crosshead.
