Stainless Steel Fasteners


A Stainless Steel Fastener is recognized by a helical ridge, known as a male thread or thread just wrapped around a cylinder. A bolt or screw is kind of fastener. Some screw threads are known as female thread as they are designed to mate with a complementary thread, some times in the form of a nut or an object which has an internal thread formed into it. Because other screw threads are designed to cut a helical groove in a softer material as the screw is inserted. The screws are mostly used for holding objects together and positioning together. A screw contains always a head on one side and contains a special formed shape which allows it to be turned, with a tool. Common tools which are kept for driving screws include wrenches and screwdrivers. Generally, the head is larger than the body of the screw and keeps the screw from being deeper than the length of the screw and provides a bearing surface. The portion known as shank is the cylindrical portion of the screw which is underside the head to tip. It may be partially or fully threatened. There is a distance between two threads and it is known as pitch
