Stainless Steel Grub Screw

Allen Grub Screws are a type of fastener, in some ways similar to a bolt, typically made of metal, and characterized by a helical ridge, known as a male external thread. Allen Grub Screws are used to fasten materials by digging in and wedging into a material when turned, while the thread cuts grooves in the fastened material that may help pull fastened materials together and prevent pull-out. There are many Allen Grub Screws for a variety of materials; those commonly fastened by Allen Grub Screws include sheet metal, wood, and plastic.
