Machine Screws are uniformly threaded with UNC thread style screws designed to be fastened into tapped holes, or used in conjunction with nuts to join two or more assemblies together. Typical applications for machine screws include fastening components of tools, appliances, machines, and electronic devices. ASME B18.3 covers the general requirements for the dimensions and performance of Carbon Steel Machine Screws. It features Zinc Plated, Corrosion Resistance.

Machine Screws feature straight shank fasteners with external threads designed to go through a hole or nut that is pre-tapped to form a mating thread for the screw. Fasteners are durably constructed of steel for long lasting reliability and strength.
