For many years, Profile Grinding has applied our centerless grinding skills to increase the value of commodity parts, turning an ordinary fastener- such as a bolt, screw, or dowel pin, into a specialty fastener suited for the job at hand. Special features that may be ground into these fasteners include slots, flats, undercuts, and tapers. We also have experience with a variety of materials, including various steels and stainless steels, titanium, Hastelloy, Inconel, and Monel.
