Product Description
Precision CNC Turned Round Head Bolt - Custom Non-Standard Dimensions & Threads
Product Overview
Our Precision CNC Turned Round Head Bolt is engineered for industries requiring exacting tolerances and bespoke fastening solutions. Perfect for aerospace, medical devices, and high-end machinery, this bolt is crafted via CNC turning to achieve ±0.01mm precision, ensuring flawless fitment in custom or non-standard assemblies. Available in stainless steel, titanium, or alloy steel, it supports unique dimensions, thread profiles, and finishes tailored to your specifications.
Key Features
✅ CNC Precision Machining
- Tight Tolerances: ±0.01mm accuracy for critical applications where standard bolts fall short.
- Custom Geometry: Non-standard diameters, lengths, and thread pitches (e.g., M3×0.35mm to M24×3mm).
✅ Material Versatility
- Stainless Steel (A2/A4): Corrosion-resistant for medical, marine, or chemical environments.
- Titanium (Grade 2/5): Lightweight, high-strength option for aerospace and motorsports.
- Alloy Steel (Grade 8.8/12.9): Heat-treated for extreme load-bearing applications.
✅ Custom Thread Profiles
- Metric/Imperial/Non-Standard: ACME, trapezoidal, or proprietary threads for specialized assemblies.
- Surface Treatments: Electropolishing, passivation, or black oxide for enhanced performance.
✅ Round Head Design
- Smooth, Low-Profile Finish: Reduces snagging risks in tight or rotating assemblies.
- Drive Compatibility: Slotted, Phillips, or Torx drives (customizable).
✅ Quality Assurance
- 100% Inspection: CMM (Coordinate Measuring Machine) verified for dimensional accuracy.
- Certifications: ISO 9001, AS9100 (aerospace), RoHS, and REACH compliance.
