Socket Cap Screws are reliable and durable and are used in many applications. They are available in a variety of head styles and materials. With a high cylindrical head, socket cap head fasteners have a recessed driving area and offer high hold power at high torque levels. Hex socket drive systems are driven by hex wrenches or power tools with hexagonal bits. The size name of a threaded fastener includes information about the major external diameter, followed by the threads per inch, which indicates if it is coarse or fine. Coarse threads are better when working with brittle materials; they are sturdier and are easier to thread and unthread compared to fine. Used widely in the home and office appliance, equipments, communication equipments, ship assembly and other machinery industry.
