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.
