 Carbon Steel Hexagon Socket Head Bolt is a hex socket bolt, also known as the socket head cap bolt, is a headed and externally threaded part designed for insertion through a close tolerance internally tapped hole and mated with a nut. Tension on the hex socket bolt is induced by rotation of the bolt head. There is a hex socket in the head that accepts a hex wrench to tighten the socket head cap bolt. The point at the threaded end of the socket head cap bolt is machined flat so it will fit into a drilled hole.

   More than 90% of the fasteners manufactured by carbon steel. The reason is very simple, carbon steel has excellent work performance; Strength properties can be gained through various; And compared with other common fastener materials, its price is also very cheap. In general, the carbon steel in use can be three kinds: low carbon steel, medium carbon steel, and alloy steel.

Low carbon steel used in the manufacture of low carbon steel fasteners, defined as those with low carbon content to facilitate the strength of carbon steel heat treatment process can have a predictable response. The most commonly used is AISI 1006, 1008, 1016, 1008, 1021 and 1022.The carbon steel has good work performance, they can be hardening or be welding, they can also continue to improve its strength characteristics by cold working processing.
