Stud Bolt

Stud has a thread on full lengths or at both ends. As shown in images. It is having three components if washers are not used (two nuts and stud). If you used washer it would become five. Sometimes additional nuts are used for hydraulic tensioning with larger size stud.

The length of stud bolt should be enough to cover entire Nut plus 1.5 to 3 threads exposed. Long studs must be avoided as it increases the chance of corrosion and other damage to exposed threads, which would make subsequent removal difficult. ASME B16.5 gives the required size of the stud. Length of the stud depends on the type of gasket and the maximum exposed thread requirements.

Machine Bolt

Bolts have a thread at one end and hexagonal head on another end. In the process, piping bolts are used with lower strength flange types such as GRE/GRP, bronze. Usually, washers are used with bolt to prevent excessive load to the flange.

If you are looking for Bolts then do consider Apex MS flanges.
