Product Description

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 that allows for simple "by-hand" installation. The thumb screw has a hex head, which can be tightened with a wrench for increased torque. The head height is also tall enough to grip with fingers. Plain stainless steel 300 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.
