Anyone who works on a project can tell you that machine screws are not just screws. People who have had to use the wrong kind of driver will testify to the importance of the right head. People with sharp ends sticking out of their projects will go on about length. Too small of a screw can be untrustworthy and dangerous to rely on. Whatever kind of screw you need, Fastener Express is sure to have it. If you have any questions or comments, please use the "Contact Us" link at the top of the page.
