Be glad you did not need a ¼" BSF thread! (British Standard Fine) I have a lathe made by Myford which needs a bolt or stud of that type to disassemble the headstock and replace grease. I have looked all over the USA, and have emailed Myford.... and today I find theyhave gone out of business. Sale was a month ago.
