What is a double head stud

The diameter, length and quantity of the stud studs should meet the requirements. The type and material of the stud studs should be determined by grade. There are two commonly used stud studs (also called full threaded studs), two kinds of thread and fine teeth. The common thread of the rough teeth is expressed by M and nominal diameter. The common thread of the fine teeth is expressed by M and the nominal diameter of the screw. The fasteners standard stipulates that the bolts for M36 are coarse teeth, and M36 and above diameters can be made of fine thread, with pitch of 3.
Bm=1d double head stud is generally used for the connection between two steel joints; bm=1.25d and bm=1.5d stud studs are generally used for the connection between cast iron and steel connected parts; bm=2d double head studs are generally used for connection between aluminum alloy and steel connected parts. The preceding connector has an inner threaded hole, and the latter connector has a through hole. The two ends of the equal length stud stud should be matched with nuts and washers for two connecting pieces with through holes.
