Custom Nuts and Bolts Manufacturing
Custom Nuts and Bolts Manufacturing
As a custom nut manufacturer, we support customers requiring precision fastening components for industrial machinery, automation equipment, and heavy-duty structures.
Details
Machining Service
- Component diameter: Ø0.8 mm ~ Ø51 mm
- Machining tolerance:
- ±0.003 mm for copper and aluminum materials
- ±0.005 mm for other materials.
- Actual tolerances vary by material, part design, and customer requirements. For example, the typical tolerance for nuts and bolts is ±0.02 mm.
Why Thread Accuracy Matters for Custom Nuts and Bolts
Thread accuracy directly affects how nuts and bolts fit together. Proper thread control helps maintain stable fastening force and prevents assembly issues during long-term operation.
Precision machining helps improve:
- Accurate thread engagement
- Stable tightening performance
- Better connection strength
- Reduced assembly variation
- Improved equipment reliability
Practical examples
- For industrial machinery, accurately machined threads help ensure nuts and bolts achieve proper tightening force, reducing the risk of loosening during operation.
- For heavy-load structures, consistent thread dimensions help distribute fastening pressure evenly and maintain structural stability.
Material Selection for CNC Machined Nuts and Bolts
The material selected for nuts and bolts depends on application requirements such as load capacity, corrosion resistance, weight control, environmental exposure, and assembly conditions.
Other machinable materials, apart from those listed below, are detailed on this page.
Titanium (CP1~CP4, Ti-6Al-4V) for Lightweight High-Strength Fasteners
For applications requiring lightweight structures, titanium nuts and bolts provide reliable fastening performance while reducing overall system weight.
Typical applications include: Aerospace structural fasteners, Lightweight mechanical assemblies, High-performance equipment connections.
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 Heavy-Duty Fastening Applications
For heavy-duty mechanical structures, steel nuts and bolts help maintain stable fastening force under continuous loading.
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 fasteners, Heavy-load structures, Automation equipment assemblies, Mechanical fixtures.
Why it is selected:
- High tensile strength
- Excellent wear resistance
- Suitable for heat treatment
- Supports demanding industrial environments

Surface Treatments for Custom Nuts and Bolts
Nuts and bolts require stable thread engagement and surface durability under repeated assembly, vibration, and mechanical loading. Proper surface treatment helps protect fastening components, improve corrosion resistance, and maintain reliable connection performance.
Other machinable materials, apart from those listed below, can be found on this page.
Hot-Dip Galvanizing for Outdoor Fastening Applications
Hot-dip galvanizing is commonly used for fastening components exposed to outdoor environments or requiring long-term corrosion protection.
Nickel Plating for Enhanced Corrosion Resistance
Nickel plating is suitable for fastening components requiring improved surface protection and stable appearance.
Other surface treatment options can be found on this page for reference.
