There are many styles of anchor bolts, because of the extensive role of anchor bolts, so in view of some simple anchor bolts, derived from various forms of anchor bolts. One of the most widely used is 7 – word anchor bolt, also known as L – type anchor bolt. Compared with the 9-character anchor bolt and other forms of anchor bolt, the 7-character anchor bolt production is more labor saving, but also played the same role in use, are used to strengthen the object. General anchor bolts using Q235 steel, that is, light round. Screw steel (Q345) strength, do nut thread buckle no light round easy. In the current project, the size of the anchor bolt is determined by the design load. For example, the size and specifications of the anchor bolt such as M20 and M24 are different, and the form of the bend hook is different, and its length is also different. The length of each type of anchor bolt is different.

One anchor bolt with two nuts, according to the thick nut GB/T6175-2000, more corrosion resistance.

When mechanical members are installed on a concrete foundation, the J-shaped and L-shaped ends of such bolts are embedded in concrete for use.

The tensile strength of the anchor bolt is the tensile strength of the round steel itself, the size is equal to the section area multiplied by the allowable stress value (Q235B:140MPa, 16Mn or Q345:170MPA) is the allowable tensile strength of the design.
