All About Thread Cutting Screws
Thread cutting screws come in several different type, each of which features a blunt tip. Each style also features a different style of chip cavity; either lines or a section that is cut out of the end of the screw threads, allowing them to cut mating threads into the material into which they are being installed.
Start here to filter through all of our Thread Cutting Screw styles!
