Product Description

Stud, also known as double-ended screw or double-ended stud. It is used to connect the fixed link function of the machine. The stud bolt has threads at both ends, and the screw in the middle is thick or thin. Generally used in mining machinery, bridges, automobiles, motorcycles, boiler steel structures, pendant towers, long-span steel structures and large buildings.

Bolts refer specifically to screws with larger diameters and may also have no heads, such as stud bolts. In general, it is not called a “stud bolt” but a “stud stud”. The most common form of stud is threaded at both ends and a polished rod in the middle. The most typical use: anchor bolts, or places similar to anchor bolts, thicker connections, when ordinary bolts cannot be used.
