HCH High Quality Hex Bolt Zinc  

HCH Hardware is a bolt manufacturer that has provided various fasteners since 2008. Our main products include standard bolts, nuts, screws, washers, pins and OEM parts. Carbon steel is defined as any steel with a carbon content of up to 2.1% by weight. With the increase of carbon content, carbon steel bolts will become harder and stronger after heat treatment. However, the toughness of steel becomes weaker. No matter what heat treatment is carried out on carbon steel alloy, the higher carbon content in the material will reduce the weldability of carbon steel fasteners, and also effectively reduce the melting point of bolts. Most carbon steel studs are generally relatively soft. They also show low intensity. However, low carbon steel has high flexibility. High ductility is a characteristic that makes the material very suitable for processing and welding. Unlike other types of steel, the lack of different elements (used as alloys) is the reason why nuts…
