3/16-200 Fine-Adjustment Screw and Bushing Sets
Our series of 200 TPI (threads per Inch) screw and bushing matched pairs push the capability limit of screw machines to consistently maintain such a fine thread. Second only to our 254 TPI screws for ultra fine adjustment, these screws have a pitch of 0.127 mm/rev (127 µm/rev) allowing for submicron adjustment capability.
These 200 TPI ultra fine adjustment screws are made in the USA and sold from stock in common sizes (3/8 in, 1/2 in, 5/8 in, 3/4 in, 1in, 1 1/4 in, 1 1/2 in, 1 3/4 in and 2 in long). The 3/16-200 come pre-paired to a bushing at the factory to assure the tightest fit possible and to prevent debris from being caught in the threads.
