Products Description
Threaded rod features continuous threads along its entire length, enabling secure fastening, adjustment, and connection at any position using nuts. Typically supplied in continuous lengths, it can be cut to various sizes as needed and locked in place with nuts, offering exceptional versatility.
Standard bolts face two major limitations: limited maximum length (generally not exceeding 800mm) and fixed mounting positions at both ends. This is because bolts only have threads at specific sections.
Threaded rod resolves these issues:
Unlimited length (can be extended)
Nuts can be installed at either end
Can be locked at any position along its length
Can be quickly cut and assembled according to on-site requirements
Additionally, our company can customize products and lengths to meet your specific needs. Provide us with your drawings and requirements, and we will offer a tailored solution. Click the button below for a free consultation!

Applications of Threaded Rods in the Industrial Machinery Sector
In machine tools, automated equipment, and heavy machinery, threaded rods serve as critical components for linear motion transmission. Their primary function is to convert the rotational motion of motors into smooth, straight-line movement for slides and worktables, while ensuring positioning accuracy and load-bearing capacity.
CNC Machine Tools
Ball screw threads are employed in the feed systems of spindle heads and turrets. By replacing sliding friction with rolling friction between threads and balls, they achieve micron-level positioning accuracy, ensuring dimensional consistency in part machining-such as the feed motion during precision gear or mold fabrication.
Automated Production Lines
Within robotic arms and conveyor line lifting mechanisms, threaded rods collaborate with motors to drive actuators in performing grasping, lifting, and pushing actions. For instance, in lithium battery production lines, cell handling mechanisms utilize threaded rods to achieve precise vertical movement and translation.
Heavy Machinery
In telescoping boom mechanisms of cranes and hydraulic equipment, high-strength threaded rods bear massive axial loads. They enable boom extension and retraction through screw transmission. For instance, the telescoping boom of a port container crane relies on alloy threaded rods' high strength and wear resistance to ensure operational safety.
Key Selection Criteria
- Load Requirements: Select material and thread specifications based on axial load in the application scenario to prevent thread deformation or breakage due to overload.
- Precision Requirements: Prioritize ball screw threaded rods for high-precision transmission applications; use standard trapezoidal threaded rods for general fastening or adjustment scenarios.
- Environmental Conditions: For outdoor, humid, or corrosive environments, prioritize stainless steel or corrosion-resistant coated screws. In high-temperature conditions, select high-temperature alloy screws.
- Installation Method: Select screw length and diameter based on installation space. Coordinate with corresponding nuts, bearings, mounting brackets, and other accessories to ensure smooth transmission.
