Steel Hexagon Screw Head Bolts Hex Cap Bolts For Construction Automobile Engineering Industries
Hex Head Bolt Overview:
Bolt: A mechanical part, a cylindrical threaded fastener equipped with a nut. A type of fastener consisting of a head and a screw (cylinder with external threads). It needs to be matched with a nut and is used to fasten and connect two parts with through holes. This type of connection is called a bolt connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection.
Product use: mechanical parts
Hex Head Stainless Steel Bolts Application:
Bolts are indispensable in daily life and in industrial production manufacturing. Bolts are also called the rice of industry. It can be seen that bolts are widely used. The application scope of bolts includes: electronic products, machinery products, digital products, power equipment, and electromechanical machinery products. Bolts are also used in ships, vehicles, water conservancy projects, and even chemical experiments.
Anyway, bolts are used in many places. Especially precision bolts used in digital products. Micro bolts used in DVDs, cameras, glasses, clocks, and electronics; general bolts used in televisions, electrical products, musical instruments, furniture, etc.; large bolts and nuts used in engineering, construction, and bridges; transportation equipment, airplanes, trams, and automobiles etc. Use both large and small bolts.
