Bolts

To connect two flanges with each other, also bolts are necessary.

The quantity will be given by the number of bolt holes in a flange, diameter and length of bolts is dependent of flange type and Pressure Class of flange.

The most used bolts in Petro and chemical industry for ASME B16.5 flanges are Stud Bolts. Stud Bolts are made from a threaded rod and using two nuts. The other available type is the machine bolt that using one nut. On this site only Stud Bolts will be discussed.

Dimensions, dimensional tolerances etc. have been defined in the ASME B16.5 and ASME 18.2.2 standard, materials in different ASTM standards.
