What is the difference between machine screws and self-tapping screws?

Machine screws are designed to be used with a pre-tapped hole or nut, while self-tapping screws create their own threads as they are driven into the material, eliminating the need for a pre-formed nut thread.

Do you offer socket head cap screws?

Yes. We supply socket head cap screws in a range of sizes and materials for precision industrial and machine-building applications.

What materials are your screws available in?

Our screws are available in carbon steel, stainless steel, and alloy steel, with finishes selected to suit the corrosion resistance and load requirements of each application.
