| Certification | ISO9001 & TS16949 |
| Model Number | ST-800013 |
This hardware fitting is specifically designed for door and window construction applications. Manufactured through cold metal extrusion process using SS304 stainless steel, this cold heading rivet is a high-toughness integrated precision connecting fastener. Unlike conventional turned cutting rivets, it features no fractured metal grain structure, making it ideal for various riveting scenarios including industrial chain connection, sheet metal fixing, fluid hardware assembly, and mechanical component fastening.
All finished products undergo comprehensive factory sampling inspection, with materials meeting EU standards and maintaining unified appearance integrity. The rivet adapts to two major working conditions: static pressure bearing and dynamic reciprocating vibration, delivering firm riveting performance suitable for batch riveting operations on automatic assembly lines.
Formed by normal-temperature closed-loop cold extrusion, this process preserves the original metal grain structure of SS304 raw material. The rivet body maintains uniform overall density, resisting cracking and deformation under force. Standardized limiting dies ensure key dimensions including shank outer diameter, head eccentricity and overall length are strictly controlled within industry tolerance ranges.
Manufactured with high-precision mirror sealed cold heading dies, the forming ports are fully closed without gaps. No extrusion flash, sharp burrs or cutting tool marks exist on rivet head fillets, shank ends and closing positions. The uniform and smooth surface texture enables smooth insertion into mounting holes during riveting.
Designed to fit matched standard connecting parts for locking and riveting, achieving compact gap-free fitting surfaces. This design offsets vibration generated by equipment startup and chain operation, preventing riveting looseness, displacement and falling off in high-frequency dynamic working scenarios.
Made of original SS304 stainless steel, it resists condensed water vapor, workshop oil contamination and mild acid-base corrosion. The dense cold-forged body provides excellent tensile and shear resistance, preventing rivet fracture during high-speed chain operation and bending load.
Unified tolerance compatibility with CNC automatic riveting machines ensures smooth feeding without jamming. The smooth edge-free structure prevents scratching of sheet metal coating and galvanized layers, while the cold-hardened surface enhances riveting clamping force.
No metal debris or burr shedding prevents blockage of tiny fluid holes and interference with surrounding sealing rubber rings. The corrosion-resistant stainless steel material fits humid closed kitchen and bathroom working conditions, supporting easy assembly and disassembly with uniform assembly gaps.
Solution: Made of qualified solid SS304 stainless steel wire via one-piece cold heading, the rivet has compact metal structure with stronger impact resistance than split processed rivets, fundamentally solving rivet rusting and breaking failures.
Solution: Fixed closed-loop cold heading limiting dies strictly control rivet head eccentricity and shank tolerance, matching high-speed automatic riveting equipment to reduce assembly jamming and riveting deviation rejection rate.
Solution: Mirror die forming plus finished product passivation dual treatment ensures all corners adopt fillet transition without exposed sharp burrs, maintaining complete sealing performance of fluid hardware and valve parts.
