Product Description
High - quality, high - strength brass (H59) square hammer head bolts (GB/T 8 compliant) with a plain finish deliver reliable fastening in decorative, electrical, and light - duty mechanical applications. Brass’s inherent corrosion resistance and golden appearance make it suitable for architectural trim, furniture hardware, and electrical connectors. The square hammer head’s flat surfaces ensure stable grip during manual tightening, while the plain finish reduces friction and eliminates the need for extra coating. Compliant with GB/T 8, these bolts guarantee dimensional accuracy and compatibility with standard fastener systems. Their combination of strength, aesthetics, and corrosion resistance makes them a preferred choice for applications where both form and function matter.
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.
