They have an easy-to-turn head that allows for simple “by-hand” installation like conventional thumb screws. The adjusting screw is best suited where frequent adjustments must be made. The black oxide coating provides some lubricity to the product meaning that there is less friction generated when using these products. The coating also provides a mild corrosion resistance but should not be relied on in environments where corrosion resistance is a primary concern. Carbon steel provides strength. The screw has a two-piece construction and straight knurl on the head for easier grip. A threaded fasteners size name includes information about the major external diameter followed by the threads per inch which indicates if it is coarse or fine.
