M6 M8 M10 M12 M16 full thread rod

Double stud rod application scenarios:
Double-ended rod is widely used in electric power, medical equipment, chemical industry, oil refining, valves, railways, Bridges, steel structure, auto and motorcycle parts, machinery, boiler steel structure, hanging tower, long-span steel structure and large buildings.

Equal length double rod

Class B isometric double-ended stud rod refers to the national standard GB901-88, which specifies the thread diameter of M2-M56 and the isometric double-ended rod of class B.
The threads at both ends of the equal-length double-ended stud rod must be matched with nuts and washers for two connected parts with through holes. This connection form is called a stud connection, which is also a detachable connection. It is mainly used for occasions where one of the connected parts is thick, requires compact structure, or is not suitable for bolted connection due to frequent disassembly.

Application of equal length double rod : Class B equal length double stud rod is often used to connect the thickness is large, ordinary bolts can not be connected, such as concrete roof truss, roof beam suspension monorail beam suspension, etc., but also used in the main body for large equipment need to install accessories, such as mirrors, mechanical seals, reducer rack, etc.
Because the GB901 length double stud is installed, easy to disassemble, replace and maintain, very convenient, the use is also more widely used, more used in electric power, chemical industry, oil refining, valves, railways, Bridges, steel structure, auto and motorcycle parts, machinery, boiler steel structure, hanging tower, long-span steel structure and large buildings.
Full thread rod 
Full screw stud, also known as tooth rod, screw, tooth, etc., is different from the bolt that it does not have a head, is a cylindrical fastener with full thread. Some double-ended studs rod are shorter in length, allowing all threads to be made on the stud such as GB 901-1988 double-ended studs. When L≤50mm or L≤2b, it is a full-threaded stud. Usually, we will length less than or equal to 1m full-threaded stud rod, called the rod, when the length of more than 1m, it is habitually called the rod.
The national standards for dental strips are: DIN975, DIN976, GB15389, ANSI 18.31.2, ANSI/ASMEB18.31.3 and so on.
At present, we produce full screw stud rod product specification for M3-M64. It can also produce finer teeth strips US 4# -40UNC.
The full thread stud rod is divided into carbon steel or alloy steel and stainless steel teeth from the material. The grades of carbon steel or alloy steel are divided into: 4.8, 5.6, 5.8, 8.8, 10.9 and 12.9. Also can provide stainless steel A2-70,A4-70, ASTM A193 B8 CLASS1, ASTM A193 B8 CLASS2, alloy steel ASTM A193 B7 and other materials products. Stainless steel with special needs can also be solid solution treatment.

Full-threaded rod are generally used as connections between thicker parts and are mostly used for fastening in the mechanical industry. Widely used in aerospace industry, electronics, machinery, chemical industry, military industry, metallurgical machinery, mold industry, hydraulic assembly, automotive industry, solar energy industry, wind power industry, cleaning machinery, food and beverage processing equipment, sewage pump, impurity pump, sewage treatment equipment, cold storage, communication, construction and other industries.
