Carbon Steel Support Rivet Shaft and Connecting Screw is a high-strength integrated riveted fastening component specially designed for mechanical structural support, precise positioning and stable connection. Made of high-quality carbon steel material, this rivet shaft fastener features excellent hardness, strong tensile strength and superior shear resistance, perfectly adapting to long-term load-bearing and high-vibration mechanical working conditions.

Adopting professional CNC precision machining and cold forging technology, the product has smooth surface, accurate dimensional tolerance and high structural stability. The integrated riveting and connecting structure realizes dual functions of structural support and locking connection, effectively solving component shaking, positioning deviation and loose connection problems of mechanical equipment.

It is widely used for automation machinery, equipment bracket assembly, mechanical parts fixing and structural reinforcement. We provide full non-standard custom machining services for different shaft diameters, lengths, thread specifications and rivet structure shapes.

• High-Strength Carbon Steel Material: Premium carbon steel raw material ensures high hardness, strong toughness and excellent load-bearing capacity, not easy to deform under long-term mechanical pressure and vibration.
• Dual Support & Connection Function: Integrated rivet shaft and connecting screw structure realizes structural support, precise positioning and locking fastening in one component, improving assembly efficiency.
• Excellent Riveting Firmness: Standard rivet forming structure provides tight fitting effect, effectively preventing component displacement and loosening during equipment operation.
• Precision Machining Technology: Strict tolerance control, smooth burr-free surface and high straightness, ensuring zero-gap matching and accurate mechanical positioning.
• Strong Vibration Resistance: Compact riveted locking structure absorbs mechanical vibration, maintaining long-term stable connection without loosening or falling off.
• Full Non-standard Customization: Support custom shaft size, length, thread specification, rivet head shape and special structural machining according to drawings and samples.

Carbon steel support rivet shaft fasteners are widely used in industrial automation equipment, mechanical transmission structures, equipment bracket assembly, electromechanical parts fixing, mechanical mold accessories and general industrial machinery assembly. They are essential high-strength fastening parts for mechanical structural support and stable riveted connection.

We have introduced advanced equipment and technology from Japan and Germany (CNC 5-axis and 6-axis machines). Our maximum processing outer diameter is 60mm, and the minimum control tolerance is 0.001mm.
