We combine screws from production to delivery to customers. Throughout this entire process, we need to conduct quality testing on the combination screws. Only in this way can the quality of the combined screws be guaranteed. Only in this way can customers feel more confident and boldly use our screws. So, what are the common quality issues we encounter when measuring the quality of combination screws! Next, the technicians from Baolu Hardware will briefly introduce it. For reference only. Usually as follows:

1. Poor molding

2. Eccentricity, imprinting, deviation, shortage, burst, etc

3. Poor tooth rubbing

4. Rotten teeth, poor GONOGOGAUGE, poor pulling nails, poor burning nails, etc

5. Poor scale

6. Length, outer diameter, bone diameter, angle, etc

7. Poor electroplating

8. Blackening, color difference, etc

9. Poor trust

10. Poor salt spray test, poor torque, poor hardness, poor hydrogen embrittlement, poor cracking, poor tooth slip, etc

11. Poor environment

12. Poor materials (including harmful substances), poor electroplating, etc
