Brass Screw Manufacturing: Precision CNC Machining
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!)

FAQ
1. Are you a manufacturer or a trading company?
We are a factory located in Shenzhen, China, with 20 years of rich experience,
covering 6000 square meters. Complete facilities, including 3D quality inspection equipment, ERP system and 40 machines. If necessary, we can provide you with material certificates, sample quality inspection and other reports.
2. How to get a quote?
Detailed drawings (PDF/STEP/IGS/DWG...), including quality, delivery date, materials, quality, quantity, surface treatment and other information.
3. Can I get a quotation without drawings?
Can your engineering team draw for my creativity? Of course, we are also glad to receive your samples, pictures or detailed size drafts for accurate quotation.
4. Can you provide samples before mass production?
Of course, the sample fee is necessary. If possible, it will be returned during mass production.
5. What is the delivery date?
Generally, the sample lasts for 1-2 weeks and the batch production lasts for 3-4 weeks.
6. How do you control quality?
(1) Material Inspection - Check material surfaces and approximate dimensions.
(2) First inspection of production - ensure
critical dimensions in mass production.
(3) Sampling inspection - check the quality before delivery to the warehouse.
(4) Preshipment inspection - 100% inspection by QC assistant before shipment.
7. After sales service team
If you have any problems after receiving the product, you can provide feedback through voice call, video conference, email, etc. within one month. Our team will provide you with solutions within a week.
