Stainless Steel Rivet Self-Clinching Screw
Products Description
The essence of the Stainless Steel Rivet Self-Clinching Screw lies in its integrated design of self-clinching and threaded connection. During the clamping process, the screw's special grooves or recesses plastically deform with the thin sheet material, forming a permanent mechanical interlock while providing a standard threaded interface.
Typical features include:
Stainless steel base material: Excellent corrosion resistance, suitable for various working environments.
Self-clinching structure: After clamping, a flange or deformation zone is formed on the thin sheet, achieving high pull-out force.
Thread integrity: The thread maintains its standard specification after installation, facilitating subsequent bolt or nut connections.
Thin sheet adaptability: Suitable for sheet materials with thicknesses from approximately 0.5mm to 3mm, depending on the specifications.
Main Functions
| Mechanical Anchoring | The cold-extruded zinc-plated pressure riveting self-clinch stud forms an interference fit with the sheet metal, providing primary shear and pull-out resistance. |
| Threaded Clamping | The M5 Self Clinching Screw head generates axial clamping force between the screw and the sheet metal via threads, pressing two or more layers of sheet metal together. |
| Positioning Function | The combination of pre-punched holes and the Screw Carbon Steel Self Clinching Stud rod diameter achieves precise positioning between sheet metal layers, with a positioning accuracy of ±0.1mm. |
| Sealing Function | The anchoring structure fills the pre-punched holes, preventing loosening in vibration environments and serving as a simple sealing node. |
Production Process
Raw Material Inspection: Chemical composition analysis and hardness testing are performed on SUS304 stainless steel wire to ensure the material meets standard requirements.
Cold Heading: A multi-station cold heading machine is used to complete wire cutting, head pre-heading, tooth embossing, and shank stretching at room temperature. The cold heading process ensures continuous metal flow lines along the Self-Clinching Weld Screws for Automotive shape, resulting in higher head strength than machined parts.
Thread Rolling (Thread Rolling): An external thread is formed on the shank using a thread rolling machine. The rolling process work-hardens the thread surface, improving Zinc Plated Pressure Riveting Self Clinch Stud's thread strength and wear resistance.
Cleaning and Degreasing: Ultrasonic cleaning or hydrocarbon cleaning is used to remove residual lubricating oil and metal debris from the cold heading and thread rolling processes for M5 Self Clinching Screw.
Product Advantages
Significantly Simplified Assembly Process
This Screw Carbon Steel Self Clinching Stud eliminates the need for traditional spot welding or TIG welding, removing sheet metal deformation, scorching, and slag cleaning processes caused by high welding temperatures.
Extremely High Mechanical Resistance
Thanks to the principles of cold flow fluid dynamics, the metal matrix tightly encapsulates the fastener, giving Self-Clinching Weld Screws for Automotive extremely high pushout value and torsion-out resistance.
Provides Clean Threaded Pairs
Welded screws often suffer from thread damage due to weld spatter, while press-fit Zinc Plated Pressure Riveting Self Clinch Stud, installed through pure mechanical pressure, ensure undamaged and high-precision internal and external threads.
Supports Ultra-Thin Sheet Metal Connections
High-strength external threads can be created on sheets as thin as 0.5mm, avoiding the design waste of increasing sheet thickness due to the inability to tap thin sheets.
