SS304 Cold Heading Rivet, Precision Fastener Hardware for Connection
| Place of Origin | GuangDong Dongguan |
| Brand Name | SITUO |
| Certification | ISO9001 & TS16949 |
| Model Number | ST-800012 |
This SS304 cold heading rivet is integrally formed using advanced cold heading technology and serves as a precision connecting fastener. Specifically designed for assembly and joining of chains, hardware assemblies, and small equipment components, the cold heading process preserves the metal grain flow of SS304 stainless steel raw material, delivering superior structural strength compared to turned workpieces with excellent dimensional consistency. Ideal for mass automated assembly applications, these rivets resist fracture and loosening during long-term operation.
The rivet is extruded in one piece via multi-station cold heading dies without secondary cutting. Critical dimensions including shank diameter, head thickness, and overall length are confined by fixed die cavities, resulting in minimal dimensional variation within the same batch. This eliminates manual sorting during assembly and supports continuous operation of automatic riveting machines.
Internal cavities of cold heading dies are mirror-polished, ensuring no flash or burrs exist at the transition between rivet head and shank after extrusion. This eliminates extensive secondary deburring procedures and prevents scratches on matching plates and chain holes, enabling smooth feeding without jamming during assembly.
All rivets with matching sections undergo full gauge testing equivalent to go/no-go gauge inspection. Uniform extruded bonding surfaces create tight, gap-free joints after riveting, effectively preventing loose connections under impact and vibration conditions.
High tensile strength prevents rivet separation under prolonged reciprocating operation. Burr-free surface reduces wear on chain plates, while SS304 stainless steel withstands moisture and mild acid & alkali corrosion for extended service life of outdoor conveyor chains.
Uniform dimensions ensure compatibility with automatic riveters. Smooth surface safeguards sheet metal coatings from assembly scratches, while dense cold-forged structure offers strong shear resistance to prevent loosening under equipment vibration.
Minimal tolerances ensure consistent assembly clearances for components. Burr-free structure avoids interference with surrounding sealing parts, and rust-resistant SS304 material suits small hardware for kitchen, bathroom, and fluid equipment applications.
Solution: Enclosed cold heading dies are adopted for shaping. A single batch is extruded within unified die cavities with narrow tolerance ranges, ensuring excellent interchangeability and compatibility with fully automatic continuous riveting production lines.
Solution: Cold heading is performed with mirror-polished die inner walls, followed by simple passivation treatment after forming. The finished rivets are completely free of flash and burrs with flat bonding surfaces, creating tight joints without clearance post riveting.
Solution: Manufactured from SS304 stainless steel via cold heading, the rivets retain continuous unbroken metal grain flow for improved tensile and shear strength. The substrate features inherent rust resistance to cope with humid and mildly corrosive working environments.
SITUO Hardware specializes in the production of SS304 stainless steel cold heading rivets and various precision fasteners. We customize rivet diameter, overall length, head profile, and riveting section specifications according to demands of chains, positioning adjustment devices, and sheet metal equipment.
To accommodate diverse working conditions, we support cold heading customization of multiple materials including 201 & 316 stainless steel, carbon steel, and copper. Supported by mature multi-station cold heading production lines and full finished-product inspection procedures, we steadily supply high-strength precision connecting rivets with stable tolerances and burr-free surfaces.
We have introduced advanced equipment and technology from Japan and Germany (CNC 5-axis and 6-axis machines) to better serve our customers' needs. Our maximum processing outer diameter is 60mm, and the minimum control tolerance is 0.001mm.
