Machine Screws
American Bolt Corporation offers a wide selection of machine screws used in manufacturing, industrial assembly, construction, and maintenance applications. Machine screws are commonly used where threaded holes or nuts are present and where consistent fastening is required across repeated assemblies.
Our inventory includes multiple head styles and drive options to support different clearance, access, and installation requirements.
What Is a Machine Screw?
A machine screw is a fully threaded fastener installed into a pre-tapped hole or paired with a nut. Machine screws rely on existing threads and are commonly used in equipment assembly, electrical components, enclosures, and general industrial applications.
Machine Screw Head Styles & Drive Options
Machine screws are available in the following head styles, with Phillips or Slotted drive options depending on size and application:
-
Flat Head: Sits flush with the surface when installed in a countersunk hole. Commonly used where a smooth or low-profile surface is required.
-
Pan Head: A widely used head style with a slightly rounded top. Often used in general assembly, electrical components, and enclosures.
-
Round Head: Features a rounded top and is often selected where the fastener remains visible.
-
Hex or Indented Hex Head: Installed using a wrench or socket, allowing higher torque for industrial and mechanical applications.
Machine Screws for Assembly & VMI Stocking Programs
Machine screws are one of the most common fasteners used in assembly work. Whether you're building equipment, panels, or sub-assemblies, it’s important to have the right screw on hand at all times. That’s why many manufacturers include machine screws in their vendor managed inventory (VMI) programs—so they don’t have to think about running out in the middle of production.
