Custom Screw Manufacturing
Custom Screw Manufacturing
As a custom screw manufacturer, we support industries that need customized screws for complex assemblies, special materials, and demanding operating conditions.
Details
ODM / OEM Screw Manufacturing Service
- Machining diameter: Ø0.8 mm ~ Ø51 mm
- Machining tolerance: ±0.003 mm for copper and aluminum materials; ±0.005 mm for other materials.
- Actual tolerances are determined based on customer requirements.
Why Precision Machining Matters for Custom Screws
Precision screws must maintain accurate thread dimensions and consistent mechanical performance to ensure reliable fastening in different applications.
Precision machining helps improve:
- Accurate thread engagement
- Stable tightening force
- Secure component connection
- Reduced assembly variation
- Improved equipment reliability
Practical examples
- For precision machinery, inaccurate screw dimensions may cause uneven tightening force, affecting component alignment and equipment operation.
- For high-vibration environments, properly machined screws help maintain secure connections and reduce the risk of loosening during long-term use.
Material Selection for CNC Machined Custom Screws
The material selected for screws depends on application requirements such as mechanical strength, corrosion resistance, weight control, temperature conditions, and environmental exposure.
Other machinable materials, apart from those listed below, are detailed on this page.
Titanium (CP1~CP4, Ti-6Al-4V) for Lightweight High-Strength Screws
For applications requiring lightweight structures, titanium screws provide reliable fastening strength while reducing overall system weight.
Typical applications include: Aerospace equipment screws, Lightweight structural fasteners, Precision mechanical assemblies, High-performance equipment components.
Why it is selected:
- Excellent strength-to-weight ratio
- High corrosion resistance
- Suitable for demanding environments
- Maintains stable performance under repeated loading
Steel and Stainless Steel for High-Strength Fastening Applications
Steel materials are commonly selected for screws requiring higher load capacity, wear resistance, and long-term durability.
Common materials include:
- Carbon Steel (S15C ~ S45C)
- Bearing Steel (SUJ2)
- Stainless Steel (SUS303, SUS304, SUS316, SUS420, SUS440C)
- Chromium Molybdenum Steel (SCM415, SCM420, SCM435, SCM440)
- Free-Cutting Steel (SUM24L/12L14, SUM25L/1215)
Typical applications include: Industrial machinery screws, Automotive fastening components, Precision equipment screws, High-load mechanical assemblies.
Why it is selected:
- High tensile strength
- Excellent wear resistance
- Suitable for heat treatment
- Supports demanding industrial applications
Other machining materials can be found on this page for reference.
Surface Treatments for Custom Screw Components
Screws are required to maintain stable fastening performance under repeated assembly, vibration, and different environmental conditions. Proper surface treatment helps improve thread durability, reduce friction during installation, and protect screw surfaces from corrosion.
Other machinable materials, apart from those listed below, can be found on this page.
Zinc Nickel Plating for Corrosion-Resistant Screw Applications
Zinc nickel plating provides stronger corrosion protection than traditional zinc coatings and is commonly selected for screws used in demanding industrial environments.
Passivation Treatment for Stainless Steel Screws
Passivation is commonly used for stainless steel screws requiring enhanced corrosion resistance while maintaining precise thread dimensions.
Other surface treatment options can be found on this page for reference.
