    Machine Screws

    A machine screw is a blunt-ended screw that is used to fasten metal parts together. They can be coarse-threaded or fine-threaded and come in a wide range of head types. Most machine screws are fully threaded, which means the thread runs the full length of the fastener, from just under the head to the very end. You can learn more in our complete guide to machine screws.
