The number 4 machine screw is the bolt with a 0.112-inch external diameter thread, it can be 40 threads per inch (UNC) or 48 threads per inch (UNF). The standard designation for a UTS thread is a number indicating the nominal (major) diameter of the thread, followed by the pitch measured in threads per inch. For diameters smaller than 1/4 inch, the diameter is indicated by an integer number defined in the standard; for all other diameters, the inch figure is given. Ever Hardware Industrial Limited aimed to be the best number 4 machine screw supply company of cold forming services. At the same time, we provide a customizable package according to your request.

The hex socket screw drive has a hexagonal recess and may be driven by a hex wrench, also known as an Allen wrench, Allen key, hex key or inbus as well as by a hex screwdriver (also known as a hex driver) or bit. Tamper-resistant versions with a pin in the recess are available.
