1/2-13 Coupling nuts, hardened, milling machine fixturing

Description

1/2-13 Coupling nuts for milling machine fixturing.   Hardened.  Coupling nuts allow for 2 fixturing tie bolts to be joined to make a longer bolt when a tall object needs to be clamped to the milling machine, CNC, VMC.  Some nuts have rust staining on them - I did not bother to oil them to pretty them up. Selling them in qtys of 10 nuts.   Part of a mixed lot of machine related tooling / hardware from the estate of a retired machine shop owner.   I have set aside coupling nuts for use on my Bridgeport (replacing the soft hardware store coupling nuts I have used in the past) and am selling off the rest.
Combined shipping will be considered but you must contact me before making payment so that I can create a combined invoice.
