Difference between double head bolts and single head bolts

The main difference between double head bolts and single head bolts is the number of threads and application scenarios. Double head bolts have threads on both ends and can be connected to two joints at the same time, while single head bolts have only one body with threads and can only be connected to one joint.

Characteristics and application scenarios of double-ended bolts

A double head bolt (Stud), also known as a double head screw or double head stud, is used to connect fixed links in machinery. It has threads on both ends and a thick and thin screw in the center. Double head bolts are commonly used in high temperature and high pressure environments, such as mining machinery, bridges, automobiles, motorcycles, boiler steel structures, crane towers, large span steel structures and large buildings.

Characteristics and application scenarios of single head bolts

Single head bolts have only one body with threads, and their usage is more flexible than ordinary bolts. It can also be used as an ordinary bolt after adding a nut to the unthreaded end. The surface treatment of single head bolts can be galvanized, hot-dip galvanized or stainless steel vibration light, and the materials are Q235, 45# steel, SUS304, SUS316 and so on. Single head bolts have a wide range of applications and are suitable for a variety of scenarios that require bolt connections.
