Material Introduction & Production Process
Our Hex Socket Button Head Screws with Collar are manufactured using high-grade carbon steel, chosen for its excellent balance of strength and affordability. The industrial process includes cold or hot forging, precision CNC machining, thread rolling, heat treatment, and an additional surface coating layer for environmental resistance.
Each stage of production is tightly controlled:
- Material selection: Sourced only from qualified steel mills
- Forging process: High-pressure die forging ensures optimum head-to-thread strength
- Thread forming: Rolled threads offer better fatigue resistance
- Surface coating: Zinc plating or black oxide prevents rust and oxidization
Typical Applications and Industry Usage
Due to their strength and clean finish, Hex Socket Button Head Screws with Collar are extensively used in:
- Automotive assembly (engine components, brackets)
- Industrial machinery (frame assemblies, maintenance kits)
- Electronics and enclosures
- Automation systems
- Aerospace and defense units (non-critical applications)
- Construction and architecture
- DIY hardware and home improvement products
They are particularly favored in scenarios where “bolt-out” issues need to be avoided, thanks to the wide load distribution provided by the built-in collar.
