How to Select Single Head Bolts According to Flange

[Abstract]:
Single head bolts for flanges are usually hexagonal head bolts and flange nuts. They are generally hexagonal and can be divided into two types: single chamfer and double chamfer. Specific analysis is as follows: bolts are divided into single-head bolts and double-head bolts according to their shape. Single-head bolts only process threads at one end of the screw, while the other end is the screw head connected to the screw body. Single head bolts for flanges are usually hexagonal head bolts. The two ends of the double-head bolt are machined with a cylindrical shape. When the tension force is large, the single head bolt is easy to break at the connection between the screw and the screw head, so it can not be used on medium and high pressure flanges. The double-head bolt can not only be used on medium and high pressure flanges, but also be easily tightened from both sides.
