Besly Round Split Screw Adjusting Dies These Besly dies are used for threading bolts, studs, rods and other pieces requiring external threads. They are round disks of hardened steel which have a slot to allow for limited adjustment in cutting size. This adjustment may be made by a screw in the die itself.
