New Half Nuts / Split Nut for Craftsman and Atlas 6″ Lathe.

ACME 1/2″x 16 Right Hand Threads.

Please Note – these are M6-12 half nuts used in the early model lathes, they are narrower than the later M6-12A nuts. The threaded portion is only 1/2″ wide. Please measure your existing nuts before purchasing to confirm fitment.

Made out of 360 Brass – much harder than the OEM Zamak nuts yet still softer than the screw.
