• Ensures concentricity and accurate inner/outer threads.

2. CNC Milling

• Creates flat surfaces, slots, special shapes, and custom geometry.

3. Thread Cutting / Thread Rolling

• Metric, UNC, UNF, BSW, fine thread, coarse thread, or custom thread designs.

4. Precision Drilling & Boring

• Ensures tight bore tolerance and smooth internal finish.

5. Heat Treatment

• Improves strength, hardness, and wear resistance for heavy-duty custom machined nuts.

6. Deburring & Precision Finishing

• Achieves clean edges and a smooth appearance for premium quality.
