Product Description
These 4.8 and 8.8 grade clinching stud bolts are produced by mature hot dip galvanizing production technology, forming thick, uniform and seamless anti-rust protective layers on the whole bolt surface. Compared with ordinary electroplating bolts, they have longer anti-rust service life and stronger outdoor weather resistance. As direct factory wholesale products, they have stable raw material sources, standardized production flow and highly competitive market price. All finished products are compatible with global standard installation tools, realizing rapid construction and efficient fixed installation. Thanks to excellent sun-proof, rain-proof and aging-resistant performance, they are widely used in outdoor steel structure construction, garden landscape facility installation, open-air mechanical equipment fixation and other long-term exposed outdoor engineering scenes.
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.
