Pin Grips for Flat Specimens

Pin Grips for Flat Specimens

User-friendly pin grips are designed for conducting tensile tests of hard metal plate specimens that are difficult to grip. Specimens are held within the grips by passing pins through holes in the specimens.

A beneficial feature of these grips is different specimen thicknesses can be accommodated because of the incorporation of specimen thickness adjustment screws, or bushings, which position the specimen at the center of the grips.

Operation

A specimen is placed within the grip faces so that the hole in the specimen is lined up with the hole in the grip faces. Bushings, followed by the pins, are inserted through the grip faces and specimen. The bushings are screwed to change the horizontal position of the specimen and line it up with the axis of the testing machine.
