A fully threaded screw with a blunt end and usually used with a nut or driven into a pre-tapped hole or threaded insert. Machine screws are extremely versitile fasteners with standardized threading and that come in a variety of sizes, materials, head styles and drives to best suit the specific application.
Flat head machine screws have a tapered base and a flat surface that sits flush or slightly below the surface when installed and helps the machine screw to center. This require a pre-drilled counter sink - usually angled at 82 degrees. Metric flat heads have 90 degree angles. For a more decorative finish an oval head might be better suited as it has a slightly rounded top that remains above the surface. FeaturesSpecifications
