Customized non-standard nuts for mechanical equipment nuts 0PPM

Our Nicht standardmäßige Nüsse are custom-designed to meet the unique specifications of your projects. Perfect for industries that require specialized fasteners, these Nicht standardmäßige Nüsse are crafted with precision to ensure a secure, reliable fit. Made from high-quality materials, they offer excellent strength, Haltbarkeit, and resistance to corrosion. Whether you need unique sizes, threads, or materials, our non-standard nuts provide tailored solutions for complex applications, ensuring optimal performance.

1. Material Selection
   High-quality steel bars or wire rods (e.g., carbon steel, alloy steel, or stainless steel) are selected based on mechanical strength, Korrosionsbeständigkeit, and application requirements.

2. Cutting / Blanking
   First, the raw material is cut into appropriate lengths or blanks using sawing or automatic feeding and cutting machines. Then, the pieces are prepared for further processing, ensuring precision and consistency throughout the manufacturing process.

3. Cold or Hot Forging
   Initially, the basic nut shape is formed using cold forging for smaller nuts or hot forging for larger or special shapes. This process enhances the structural strength, providing greater durability and reliability for the finished product.

4. Trimming & Chamfering
   After forging, the nut is trimmed to remove excess material. Subsequently, chamfering is performed to smooth the edges, ensuring easier assembly and a cleaner finish. This ensures easier assembly and improves the overall functionality of the nut.

5. Thread Tapping
   Internal threads are created using tapping machines. Thread tolerance and pitch must meet international standards (such as ISO, DIN, or ANSI).

6. Wärmebehandlung (if required)
   Nuts may undergo quenching and tempering to increase hardness, tensile strength, and wear resistance.

7. Surface Treatment
   Various coatings are applied to improve corrosion resistance and appearance:

   • Zinc plating (blue/white/yellow)

   • Black oxide

   • Phosphate coating

   • Dacromet or Geomet

   • Galvanization or nickel plating (for stainless/anti-corrosive requirements)

8. Inspection and Quality Control

   • Dimensional checks using thread gauges and micrometers

   • Hardness and torque testing

   • Salt spray testing (for coated nuts)

   • Visual inspection and sorting (automated if required)

9. Packaging
   After production, the nuts are cleaned, sorted, and packed either in bulk, small boxes, or custom packaging. Zusätzlich, we ensure full product traceability and proper labeling for efficient inventory management and quality assurance.
