Acme Nuts and Components

Keystone Threaded Products has right-hand and left-hand Acme nuts available as single start and multiple start, stub Acme forms, and classes 2C and 2G in various materials. 

We manufacture mounting flanges of various diameters and thicknesses that work as an assembly with the mating Acme nut. Mounting flanges are made from carbon steel with black oxide finish. They assist in mounting items to lead screws with an Acme thread. The Acme flange is fixed to a nut via a set screw or locking pin.
