TESTING AND QUALITY ASSURANCE

• Dimensional Inspection: Verify that the products meet the specified dimensions, including length, diameter, thread pitch, and head dimensions. Precision measuring tools like micrometers, calipers, and thread gauges are used for this purpose.
• Material Testing: Ensure that the materials used for products meet the required mechanical and chemical properties. Common material tests include tensile testing, hardness testing (e.g., Rockwell or Brinell hardness), and chemical composition analysis.
• Thread Inspection: Check the quality and accuracy of threads on products using thread plug gauges, thread ring gauges. Thread fit, pitch, and form are evaluated.
• Surface Finish Inspection: Examine the surface finish of products to ensure they meet specified requirements.
• Coating and Plating Thickness Testing: If the products are coated or plated, we measure the thickness of the coating to ensure it meets the required standards.
• Quality Documentation: Maintain detailed records of test results, certificates of compliance, and traceability data for each batch of product produced.

We have well-equipped testing and quality control lab that ensures that products meet industry standards, customer requirements, and safety regulations. It helps identify defects early in the manufacturing process, ensuring that only high-quality fasteners reach the market. Additionally, it allows us to continuously improve our processes and materials based on testing data and feedback.
