Products Description

Dual Threaded Screw is a type of fastener threaded at both ends, with a smooth or slightly raised shank in the middle, offering flexibility and high load-bearing capacity during installation. The dual-end design allows one end of the screw to be fixed to the base material, while the other end securely connects with components, achieving a stable two-way connection. It is also suitable for applications requiring disassembly, assembly or adjustment.

The product is manufactured with high-precision machining and heat treatment processes, featuring tight and uniform threads and stable dimensions to ensure smooth thread fitting. Various thread specifications, lengths and surface treatments are available to meet the fastening requirements of different industrial scenarios.

Performance characteristics

High precision	Advanced production technology and equipment are used to ensure the dimensional accuracy and thread accuracy of the screws, and to ensure the accuracy and stability of the connection. For example, the diameter tolerance of the Double-Ended Carriage Bolt is controlled within a very small range, and the pitch of the thread is uniform, which can perfectly match the matching nut or workpiece.
High strength	Made of high-strength materials such as high-quality alloy steel, after a strict heat treatment process, the screws have high tensile strength and shear strength, can withstand large loads and impact forces, and are suitable for occasions with high connection strength requirements, such as the assembly of large mechanical equipment, the connection of bridge structures, etc.
Strong corrosion resistance	The surface is treated with special anti-corrosion treatment, such as zinc plating, nickel plating, chrome plating, etc., to form a dense protective film, which effectively prevents the screws from rusting and corroding in harsh environments such as humidity, acid, and alkali, and prolongs the service life of the screws.
Space saving	The design of the Double-Ended Screw gives it a unique advantage in some application scenarios with small spaces. Only one screw is needed to complete the functions of two connection points, reducing the number of parts and installation space, and improving space utilization.
Good weldability	The Double End Fastener material has good weldability, which is convenient for connection in occasions where welding is required, further expanding its application range.
Multiple head shapes are available	A variety of head shapes are available, such as hexagonal heads, round-headed, countersunk heads, etc., to meet different installation and use requirements. Hexagonal head screws are easy to tighten and disassemble with tools such as wrenches, while round head screws are more beautiful in appearance and are suitable for occasions with high requirements for appearance.

Customized Dual Threaded Screw

Production process

Raw material procurement

Strictly screen raw material suppliers to ensure that the quality and performance of raw materials meet the requirements. Each batch of raw materials is strictly inspected and tested, and only qualified raw materials can be put into production for the Double Headed Screw.

Processing and manufacturing

Use advanced production equipment and processes, such as CNC machining centers, automatic lathes, etc., to accurately process the screws. During the processing, strictly control the quality of each process to ensure the dimensional accuracy and surface quality of the Both-end Studs.

Heat treatment

Appropriate heat treatment of the Equal Double Threaded Studs, such as quenching and tempering, improves the strength, hardness, and toughness of the screws and improves their mechanical properties.

Surface treatment

According to different use environments and requirements, the Dual End Fasteners are surface treated, such as electroplating, blackening, phosphating, etc. Electroplating can improve the corrosion resistance and aesthetics of the screws; blackening can enhance the rust resistance of the screws; phosphating can improve the wear resistance and fatigue resistance of the screws.

Quality inspection

Establish a complete quality inspection system and conduct strict quality inspections on Double Point Screws in each production link. We use advanced testing equipment and methods, such as hardness testing, dimension measurement, thread testing, etc., to ensure that the quality of our products meets the standard requirements.

Production Process of Dual Threaded Screw

Widely used scenarios

Mechanical engineering	In the manufacturing of heavy machinery and equipment, Dual-head Stud Bolts and Double-Ended Threaded Studs are often used in key parts such as engine cylinder fixing and machine tool base connection. With high tensile strength and stable performance, it ensures that all parts of the equipment are closely combined during operation, reduces the risk of vibration and loosening, and maintains efficient operation of the equipment.
Pipeline and industrial equipment installation	For pipeline systems in industries such as petrochemicals, electric power, and energy, our M10 Double-Ended Dowel Screw and other double-head screws can achieve a stable connection between pipes and flanges and brackets. Under harsh working conditions such as high pressure, high temperature, and strong corrosion, it still maintains excellent sealing and tightness to prevent leakage accidents.
Mold manufacturing and maintenance	In the mold assembly process, the high-precision Double Point Screw ensures the precise positioning of each component of the mold, ensures smooth opening and closing of the mold, and improves the quality of product molding. Its high-strength characteristics can withstand huge pressure when the mold is working, extend the service life of the mold, and reduce the production cost of the enterprise.
Architecture and Steel Structure Engineering	In steel structure projects such as bridges and high-rise buildings, the Double Point Screw is used as a key connector for steel beam splicing and prefabricated component fixing. Through reliable connection strength, the stability and seismic resistance of the building structure are enhanced to ensure project safety.
Precision Assembly of Electronic Equipment	In response to the demand for thinner and more precise electronic equipment, the miniaturized Dual Threaded Screw and Dual-head Stud Bolt are suitable for circuit board fixing and shell assembly with their high precision and small size. Its good conductivity and anti-electromagnetic interference performance ensure the stable transmission of electronic signals, while the anti-rust design protects the precision components inside the equipment.
