Wedge Clamping Grips for High-Strength Metal and Composite Specimens

Description

Wedge clamping grips use a wedge-based jaw mechanism that increases holding force as the tensile load rises. The internal wedge slides against serrated or knurled jaw surfaces, which continue to tighten on the specimen during loading.

These grips are used for high-strength materials such as structural metals and composite laminates, where high load capacity and firm holding are required. They are produced in manual and hydraulic versions and support force levels ranging from moderate test loads to capacities exceeding 500 kN.

Wedge clamping grips are used in materials testing laboratories, aerospace and automotive component evaluation, and research settings where standardized tensile tests are performed. They support testing practices such as ASTM E8 and ISO 6892 by maintaining axial load alignment and steady clamping conditions for hard, rigid specimens.
