Manufacturing Process

Our production follows strict international standards (ISO 9001):

1. Raw Material Selection – Certified 304 Stainless Steel

2. Cold Forging / Hot Forging (depending on nut type)

3. CNC Turning & CNC Milling for precise geometry

4. Thread Rolling or Thread Cutting

5. Heat Treatment (optional) to improve hardness & strength

6. Surface Treatment or Passivation

7. Full Dimensional and Quality Inspection

We manufacture CNC machined 304 stainless steel nuts, forged stainless steel nuts, and custom-made nuts based on customer drawings.

Material Advantages – 304 Stainless Steel

304 stainless steel is widely used due to its:

• Excellent corrosion resistance

• High tensile strength

• Good heat resistance

• Food-grade material properties

• Suitable for marine and outdoor applications

• Long-lasting and oxidation resistant

Ideal for producing heavy-duty stainless steel nuts that must withstand environmental exposure.

Surface Treatment Options

Although 304 stainless steel is naturally corrosion-resistant, we offer additional finishing options for aesthetics or enhanced protection:

• Passivation

• Polished finish

• Brushed finish

• Bright surface treatment

• Customized finishing per request

Precision & Quality Control

To ensure consistency and premium quality, we apply strict QC standards:

• Thread gauge inspection

• Hardness testing

• Salt-spray testing (for corrosion resistance)

• Dimensional measurement with digital calipers & CMM

• Surface roughness testing

• 100% visual inspection before packing

We supply precision 304 stainless steel nuts that meet international standards such as DIN, ISO, ANSI, and JIS.

Applications

304 Stainless Steel Nuts are widely used in:

• Automotive manufacturing

• Industrial machinery and equipment

• Construction and structural projects

• Marine applications and offshore engineering

• Outdoor equipment and hardware

• HVAC systems & electrical equipment

• Chemical equipment and food machinery

Suitable for industries that require corrosion-resistant, durable, and high-strength fastening solutions.
