The grip consists of two T slotted sample holders and two rectangular inserts. The standard inserts have M10 female threads for samples with M10 male threaded ends.


The inserts can be modified to suit a wide variety of samples. Threaded samples up to M20, standard round dumbbells, and headed samples ( screws, nails, bolts etc. ) are some of the samples that can be tested.


We can also supply plates 50mm square for adhesive testing. This test is commonly used in the timber industry where the two plates are glued either side of a sample of laminated wood e.g. plywood. The glued assembly is then placed in the holders and pulled to test the inter-laminar glue line strength. This arrangement has been used in many other industries for tension testing adhesives.


The grips have also been used for nail and screw withdrawal tests.
