Manufacturing Process

Our production integrates advanced CNC machining, turning, milling, thread rolling, and heat treatment to ensure each carbon steel screw meets strict mechanical and dimensional standards.

1. Material Preparation – Selection of certified carbon steel rods.

2. Precision Machining – CNC turning and milling for accurate geometry.

3. Thread Forming – Rolling or cutting threads with minimal deviation.

4. Heat Treatment – Optimizing hardness, strength, and wear resistance.

5. Surface Finishing – Applying plating or coating based on application needs.

6. Quality Inspection – 100% inspection before packaging and shipment.

Material Selection

We manufacture carbon steel screws in various material grades:

• Low Carbon Steel Screws: Good ductility and cost-effective, suitable for general use.

• Medium Carbon Steel Screws: Balanced strength and toughness for Automotive and machinery applications.

• High Strength Carbon Steel Screws: Heat-treated for enhanced performance under heavy loads.
  Other materials such as stainless steel, alloy steel, and aluminum are also available for hybrid fastener production.

Surface Treatment Options

To improve corrosion resistance and appearance, we offer multiple surface finishes for our carbon steel fasteners:

• Zinc Plating – Anti-rust coating with bright finish.

• Black Oxide Coating – Uniform black finish with added corrosion protection.

• Nickel or Chrome Plating – Superior appearance and surface hardness.

• Hot-Dip Galvanizing – Excellent resistance for outdoor and marine applications.

• Polishing and Passivation – Smooth, refined surface for precision equipment.

Precision & Quality Control

We maintain strict quality control standards across all stages of production:

• Dimensional accuracy within ±0.01 mm tolerance.

• Surface roughness ≤ Ra0.8 μm for fine finish.

• Full inspection using CMM (Coordinate Measuring Machine), thread gauges, and hardness testers.

• Each batch is tested for tensile strength, torque performance, and plating adhesion to ensure compliance with ISO and DIN standards.

Applications

Our carbon steel screws and fasteners are widely used in:

• Automotive Industry – Engine components, chassis, and assemblies.

• Industrial Machinery – Machine parts, housings, and gear systems.

• Construction and Infrastructure – Structural joints, metal frameworks.

• Electronics and Appliances – Mounting, assembly, and fastening components.

• Marine and Aerospace Equipment – High-strength corrosion-resistant fastening systems.
