Inspection Process for Fasteners

 

1.Receiving Inspection

• Verify incoming shipment against purchase order.      
• Check for correct quantity and part numbers.
• Inspect packaging for any damage.

                 

 

 2.Visual Inspection

• Examine fasteners for surface defects, such as cracks, burrs, or scratches.
• Ensure proper plating or coating without any irregularities.

 

3. Material Analysis

• Conduct material analysis using techniques like spectroscopy or hardness testing.
• Verify material composition and mechanical properties against standards.

        

 

 

 

 

 

4.Functional Testing

• Test functionality of fasteners by applying appropriate torque or tension.
  
• Ensure fasteners meet specified performance criteria under load conditions.

 

 

 

5.Thread Inspection

• Check thread pitch, depth, and profile using thread gauges.
• Ensure threads meet specified tolerances for proper engagement.

 

6.Dimensional Inspection

• Measure overall length, diameter, and other critical dimensions.
• Compare measurements against engineering drawings or specifications.

 

7.Salt Spray Chamber

Corrosion Resistance Testing: It is used to evaluate the corrosion resistance performance of materials or coatings by simulating salt spray environments, assessing the durability and stability of products under harsh conditions.

8.Final Inspection:

• Perform a final visual and functional inspection before release.
• Ensure all previous inspection criteria have been met satisfactorily.
