ASME A193-B7 galvanized double head studs

Double headed bolts, also known as double headed studs, belong to a special form of fastener. Its structure consists of a threaded end, a hexagonal head at one end, and a smooth cylindrical connection in the middle. Double headed bolts are widely used in fields such as mechanical manufacturing, construction engineering, and bridge construction due to their unique structure, which facilitates twisting and locking.
The purpose of double head bolts
1. Butt joint steel plate: When connecting steel plates, double head bolts can ensure a secure connection by fixing the two steel plates together. This method is safer and more reliable than traditional nails and screws.
2. Connecting mechanical equipment: When connecting mechanical equipment, double headed bolts can ensure its stability and firmness by fixing the equipment on the ground or platform.
3. Connecting the Bridge: During bridge construction, double headed bolts are used to connect the steel plates and beams on the bridge, making the bridge more sturdy and stable.

The diameter, length, and quantity of double head bolts should meet the requirements, and the type and material of double head bolts are determined by their grade. There are two types of commonly used double head bolts (also known as full thread studs), with two types of threads: coarse and fine. Coarse regular threads are represented by M and nominal diameter, while fine regular threads are represented by M and nominal diameter × Pitch representation
