Pins used to be whatever piece of metal fit the job at the time, but they have evolved into a variety of specialized forms. Using the right kind of pin is easier and safer than forcing another pin or whatever works into the slot. Fastener Express carries cotter, dowel, taper, and spring pins. All of our pins are available in a wide variety of sizes so they can fit any project. Please use the Contact Us link at the top of the page if you have any questions or comments.
