Thumb screws are designed to be tightened and loosened by hand. They come in a variety of head styles, but each includes an easy-grip head which allows for simple "by-hand" installation. The thumb screw heads straight knurled surface gives a better gripping surface, making it easier to tighten or loosen fasteners manually. It has a longer head length than standard thumb screw. Plain stainless steel 303 provides better corrosion resistance than steel. Stainless steels are used for their corrosion resistance, high-temperature strength, scaling resistance, and low-temperature toughness. These properties account for their wide use in practically every industry. A threaded fastener's size name includes information about the major external diameter, followed by the threads per inch, which indicates if it is coarse or fine.
