PRODUCT DESCRIPTION

Anchor bolts generally use Q235, Q345, that is, light round. I don't think I've ever seen the use of threads, but if the force requires it, that's fine. Rebar (Q345) is strong, and the thread of the nut is not easy to make. For the optical anchor bolt, the burial depth is generally 25 times its diameter, and then make a 90-degree bending hook about 120mm long. If the diameter of the bolt is large (such as 45mm) and the depth is too deep, you can weld the square plate at the end of the bolt, that is, make a big head on it (but there are certain requirements). The buried depth and bent hook are to ensure the friction between the bolt and the foundation, so that the bolt will not be pulled out and damaged. Therefore, the tensile capacity of the anchor bolt is the tensile capacity of the round steel itself, and the size is equal to the section area multiplied by the design value of the tensile strength (140MPa), which is the allowable tensile capacity at the time of design. The ultimate tensile strength is to multiply its cross section area (which should be the effective area at the thread) by the tensile strength of the steel (Q235 tensile strength is 235MPa).
