Hex Bolts or Screws are usually full threaded or partial/half threaded. Generally they are Hexagonal or Heavy Hexagonal Bolts/Screws where the difference is determined through their Hex head size. As the dimension of Heavy Hex Bolt across flat is more than the hex across flat, more bearing area will be covered by Heavy Hex Bolt and hence having high strength or more bearing pressure.
An Anchor Bolt is used to attach objects or structures to concrete. There are many types of Anchor Bolts all consist of thread end, to which a nut and washer are attached for the external load. Anchor Bolts are extensively used on all types of sewage projects, from standard building to dams, bridges, road, power plants etc.
