Machine Screws for Industrial and Mechanical Applications

Machine Screws are straight-shank fasteners with external threads and are designed to pass through a pre-tapped hole or a nut to form a mating thread with the screw. Machine screws offer greater strength than tapping screws and are widely used in industrial and mechanical metal-to-metal applications.

At RC Fasteners, we're a leading national supplier of machine screws. We offer a broad selection of head styles, drive types, sizes, materials, and coatings to meet the needs of manufacturers, OEMs, and industrial maintenance teams.
