Product Description
We provide full-range customized service for carbon steel clinching stud bolts, supporting personalized adjustment on non-standard outer diameter, thread length and overall size with complete strength grade selection. Different from single surface treatment, these bolts adopt integrated zinc and dacromet composite coating process, owning far stronger acid resistance, alkali resistance and salt spray resistance. The multi-layer protective structure can resist severe corrosion damage in humid, saline and chemical contaminated environments efficiently. Customized products can perfectly fit special-shaped mechanical equipment, outdoor municipal infrastructure, coastal engineering facilities and marine auxiliary hardware installation needs. Flexible production adjustment and stable product quality make these customized fasteners the preferred choice for all kinds of special environment and non-standard engineering fastening projects.
Applications
- Industrial Machinery Assembly: Used to connect heavy-duty components (e.g., gearboxes, engine blocks) in manufacturing equipment, ensuring stable load distribution during operation.
- Construction Engineering: Secures structural elements like steel beams, columns, and prefabricated panels in buildings, bridges, and infrastructure projects.
- Automotive & Aerospace: Joins critical parts (e.g., chassis frames, engine mounts, aircraft fuselage sections) where high strength and vibration resistance are required.
- Power Generation Equipment: Fixes turbine components, generator casings, and transmission systems in thermal, hydro, or wind power plants.
- Heavy-Duty Furniture & Fixtures: Assembles robust furniture (e.g., industrial workbenches, storage racks) and fixtures (e.g., machine tool bases) needing durable, long-term connections.
Material Specifications
| Aluminum |
Excellent thermal/electrical conductivity but naturally soft. May produce gelatinous buildup during processing. |
| Titanium |
EDM machining recommended. Requires deionized water to control heat during processing. |
| Steel |
Very strong metal. Wire cutting machines often preferred for complex features. Requires heat management. |
| Brass |
High tensile strength, easy to machine but requires slow cutting speed due to softness. |
Features & Advantages
- Medium carbon steel construction: Offers balanced strength (typically 4.8–12.9 grade) and toughness, suitable for moderate to high-load applications.
- Reusable & cost-effective: Can be removed and reinstalled multiple times without significant loss of performance, reducing long-term maintenance costs.
- Gasket-free compatibility: Directly interfaces with mating surfaces or nuts, eliminating the need for additional gaskets while maintaining sealing integrity.
- High-strength bolt compatibility: Works seamlessly with Class 8.8 and 10.9 high-strength bolts, enhancing overall joint reliability under dynamic or static loads.
- Durable wholeness: Manufactured with precision threading and surface treatments (e.g., zinc plating, black oxide) for corrosion resistance and extended service life.
