    Grade 10.9 bolt

    I have a small screw machine shop where I make spacers and bolts from 12l14 steel. I have a customer who wants a 10mm bolt made which must be equivalant to a grade 10.9 What material should I use and what process needs to be done after it is made to bring it to a grade 10.9?
