Hetai Custom Grade 12.9 High-Strength Positioning Nuts
Precision Positioning + Ultra-High Strength for Heavy-Duty Assemblies
Hetai custom Grade 12.9 high-strength positioning nuts are engineered for applications requiring precise location, stable clamping, and extreme load-bearing performance. Combining a Grade 12.9 high-strength body with precision positioning features, these nuts deliver superior rigidity, anti-loosening, and long-term reliability under high stress, vibration, and heavy load. Fully customizable to your thread size, positioning structure, material, and surface requirements.
Core Features
- Grade 12.9 Ultra-High Strength Manufactured from premium alloy steel with quenching and tempering heat treatment. Tensile strength ≥ 1220 MPa, yield strength ≥ 1010 MPa, providing exceptional durability for heavy-duty industrial connections.
- Precision Positioning Structure Customizable positioning shoulders, steps, grooves, flanges, or locating surfaces to ensure accurate axial/radial positioning, prevent shifting, and improve assembly consistency.
- High-Precision Thread Precision-rolled or machined threads with tight tolerance for smooth installation, uniform stress distribution, and stable fastening performance. Supports metric, imperial, fine-pitch, and custom threads.
- Full Customization Available Customize thread size (M3–M60+), outer diameter, length, positioning geometry, head style, material grade, and marking. OEM/ODM supported from drawings or samples.
- Anti-Vibration & Anti-Loosening Optimized structure and high-precision fit deliver excellent resistance to vibration, shock, and thermal cycling, reducing maintenance and failure risk.
- Multiple Surface Treatments Available in zinc plating, black oxide, HDG, Dacromet, Geomet, nickel plating, and custom anti-corrosion coatings for harsh environments.
