Round Head Machine Screws

Machine screws are a type of hardware typically used for joining wood or metal together. The screw contains a long metal shaft with a head at one end and a threaded shaft that is inserted through the hole in the material and then tightened to secure it into place. The difference between a machine screw and a regular bolt is that the threads of the machine screw are closer together which means that there is less space for error when assembling them.
