AT Dies

AT threading dies are used to cut or restore external threads on bolts, rods, and studs (application dependent). They’re commonly used in maintenance, fabrication, and repair work to create new threads, clean up damaged threads, or chase existing threads so fasteners assemble correctly. Selecting the right die starts with matching the thread standard (SAE/UNC/UNF or metric), the size/pitch, and the die style best suited to your workholding and application.
