Scissor grips function as self-tightening and self-aligning mechanisms, utilizing spring tension for initial clamping force. The larger the opening width the stronger the grips tightens the specimen. The jaws automatically tighten during force application.
These grips tend to have a larger opening compared to wedge grips and eccentric roller grips making this grip a better choice for samples with a larger thickness or diameter.
Scissor grips are a suitable choice for testing soft or compliant materials (materials that deform in response to an applied force) with irregular cross-sectional geometries, as they offer a more uniform stress distribution. They are often preferred in certain tensile testing scenarios when dealing with materials sensitive to stress concentrations. The grips exert force over a larger specimen area, mitigating the risk of localized stress and ensuring consistent test results.
We also sell test stands, load cells, and force gauges to use with our grips and fixtures.
