Grips, specimen holders, quick-change adapters, and pull rods rated for high-temperature testing in furnaces.
Quick-change adapters are typically used in hot tensile applications to provide simplified load train installation. They consist of a button-head washer that is threaded onto the room temperature end of a pull rod. The washer and pull rod are then inserted through a slot in the adapter body.

One set (2) wedge grip specimen holders made of Hastelloy X. Holders designed for tension-only loading and may be equipped to accept flat specimens from 1.13 mm to 3.18 mm thick (0.005 in to 0.125 in) by 12.7 mm to 22.225 mm wide (0.5 in to 0.875 in). Design of holders requires drilling of holes in specimen end tabs for initial loading and jaw alignment. Centering pin diameter 4.1148 mm (0.162 in). Holders are 70mm (2.75 in) long by 38mm (1.375 in) diameter contain 0.75-10f-RH thread for attachment to pull rods. Jaw inserts ordered separately, selected based on thicknesses of specimens to be tested. See W-7554-A1, -A3, and -A4 below for available inserts and corresponding thickness ranges.

Pin and clevis specimen holders are designed for flat specimens that have a hole in each end. The specimen fits into the slot of the holder and is secured by the pin.
Note: Using a specimen that is smaller (thinner) than the slot width specified for a given set of holders can result in misalignment of the specimen.
