Instron mechanical wedge action grips may be used in static or dynamic materials testing applications, interchangeable wedge-shape grip faces accommodating either flat or round specimens.
The grip is designed to allow test specimens to be securely gripped without introducing axial pre-loading to the specimen. This is achieved by using jaw faces that move in a horizontal direction only, relative to the specimen.
Application Range
Type of loading: Static or dynamic, reverse stress.
Specimen material: Metallics, plastics, composites.
Specimen geometries: Round section (not buttonhead) or flat specimens with or without shoulder tab.
