Custom OEM Carbon Steel Double Ended Yellow Blue Galvanized Non Tandard Threaded Rod Stud Rrod Double-end Bolt

This series of double-headed Threaded Rod are carbon steel galvanized double-threaded fasteners specially designed for heavy-load connection scenarios in equipment, machinery, hubs, etc. Both ends are machined with standard metric threads, allowing them to be directly used with nuts to achieve rigid connection between two components. The product covers two core structural types and two coating versions, suitable for different working conditions:

Structural classification: Full-threaded screws (the shaft body has threads throughout, suitable for short-distance connections), semi-threaded screws (the middle part is a smooth shaft body, with threads at both ends, suitable for long-distance connections and alignment requirements);

Coating version: Color zinc / Blue-white zinc passivation treatment, forming a uniform and dense protective layer, featuring both rust prevention performance and industrial texture, making it a cost-effective choice for regular indoor and outdoor working conditions.

The screws are produced by a cold forging / turning integrated forming process. The threads are precision rolled, with regular tooth shapes and strict tolerance control, perfectly matching standard nuts, ensuring a tight and non-slipping fit; the shaft body has uniform and stable strength, capable of withstanding high tensile loads, making it a universal core fastener for heavy-load connection scenarios in industrial equipment, machinery, automotive hubs, etc.

Core structure: Double-threaded without head design, divided into full-thread (the entire rod body is threaded) and half-thread (the middle part of the rod body is smooth, with threads at both ends) two types of structures.

Material and coating: High-quality carbon steel material, painted zinc / blue-white zinc passivation treatment, resistant to rust and corrosion, with outstanding cost performance.

Specification coverage: Complete thread specifications from M6 to M20, length 20-200mm selectable, supports non-standard length and pitch customization.

Performance: High strength for tensile and shear resistance, stable thread engagement and anti-loosening, galvanized layer prevents rust and corrosion, suitable for conventional heavy-duty working conditions.

Installation compatibility: Compatible with standard nuts, can be installed from both ends, no need to reserve space for a wrench, suitable for narrow / enclosed space connection scenarios.

Double-threaded headless design, suitable for narrow / enclosed spaces

The headless structure allows the installation of nuts from both ends without requiring a space for wrench operation, perfectly adapting to equipment cavities, narrow installation spaces, or scenarios where both ends need to be fixed simultaneously, solving the problem of ordinary bolts being unable to be installed.

Galvanized anti-rust treatment, suitable for regular working conditions

It adopts color zinc / blue-white zinc passivation treatment, with uniform and bright coating, forming a dense protective film, which can resist regular dampness and water vapor corrosion, has excellent rust resistance, outstanding cost performance, and is the preferred choice for indoor and outdoor regular working conditions.

Precise thread processing, stable engagement without slippage

The thread is formed by CNC rolling process, with regular tooth shape and strict control of tolerance, perfectly matching standard nuts, smooth and unobstructed when tightening, maintaining stable engagement performance even after repeated disassembly and assembly, not prone to slippage or disengagement, ensuring the reliability of heavy-load connections.

Integrated molding process, strong and durable

The body of the stud is formed by cold heading / turning integration, without welding or splicing, the rod body has uniform and stable strength, with compliance standards for tensile and shear strength, not prone to fracture or deformation during long-term heavy-load use, ensuring the safety of equipment connections.

Full coverage of multiple specifications, highly versatile

Thread specifications cover M6-M20, with lengths ranging from 20mm to 200mm, it supports national standards, German standards, etc., and can also be customized with non-standard lengths and pitch, suitable for the connection needs of most industrial equipment, machinery, automotive wheels, etc., reducing procurement and inventory costs.

Automobile and transportation scenarios

Suitable for connecting car wheels and chassis components. The semi-grooved model can achieve precise alignment of components, while the full-grooved model is suitable for short-distance connections. The galvanized model has rust prevention performance that meets the regular working conditions of vehicles, is suitable for outdoor driving environments, and does not rust over a long period, ensuring the stability of vehicle operation.

Industrial equipment and machinery scenarios

Suitable for connecting the frames of machines, pump bodies, reducers, etc. It has excellent tensile and shear resistance, suitable for heavy-duty conditions. The galvanized model is suitable for humid and oily environments in workshops, has rust prevention and corrosion resistance, and ensures the long-term stable operation of equipment.

Steel structure and construction engineering scenarios

Suitable for connecting components of steel structure factories, bridges, supports, etc. The semi-grooved model can achieve precise alignment of components, while the full-grooved model is suitable for short-distance connections. The galvanized model has rust prevention performance that meets the requirements of construction sites, has outstanding cost performance, and is suitable for batch construction projects.

Outdoor and general connection scenarios

Suitable for connecting outdoor equipment and supports. The galvanized model has rust prevention performance that meets the requirements of general outdoor environments, is not afraid of sun exposure and rain; installation is convenient, suitable for various heavy-load connection scenarios, and no additional customized accessories are required.
