If you've ever wondered how those perfect little brass screws in your electronics or jewelry get made, you're in the right place. Today we're breaking down brass screw production - from CNC milling to electroplating - in plain English.


Why Brass Screws? The Unsung Heroes of Precision Hardware
Brass screws might not get the spotlight, but they're everywhere:
✔ Electronics (conductive & non-sparking)
✔ Plumbing fixtures (corrosion-resistant)
✔ Musical instruments (aesthetic appeal)
✔ Marine applications (saltwater resistant)
How We Make Precision Brass Screws: CNC Machining Process
1. Material Selection
We start with high-quality brass rods (usually C360 for its excellent machinability). Pro tip: Lead-free brass (C48500) is becoming popular for eco-friendly applications.
2. CNC Turning - Shaping the Screw Body
Our Swiss-style lathes handle the heavy lifting:
- Single setup production reduces errors
- Live tooling allows complex geometries
- Tolerances down to ±0.01mm (that's 1/10th of a human hair!)
3. Thread Milling - The Make-or-Break Step
This is where precision matters most:
- Custom thread profiles (including micro threads)
- Anti-backlash designs available
- Surface finishes as smooth as 0.4μm Ra
Real-World Applications: Where Our Screws Excel
- Medical Devices: Our ISO 13485-certified micro screws for surgical tools
- Audio Equipment: Gold-plated brass screws for premium connectors
- Automotive: High-temp resistant plated screws for engine compartments
The Future of Brass Screw Manufacturing
We're seeing exciting trends:
- AI-assisted quality control
- Sustainable plating alternatives
- Miniaturization (we now make 0.3mm screws!)
