Threaded Rods And Eye Bolts have taken a pivotal position in today's industrial production. Product quality must not be carelessly produced and accepted in strict accordance with the corresponding standards. What are the acceptance standards for Threaded Rods And Eye Bolts?
1. First of all, Threaded Rods And Eye Bolts are also the evolution of the national standard screws. The specific inspection items should also be determined according to the national standard screw surface defect standards. Please refer to the corresponding national standards for details. If the surface coating or plating affects the surface defects Identification, it should be selected before inspection.
2. Check the dimensions and material of Threaded Rods And Eye Bolts according to the requirements of the design drawings. This should pay attention to the material detection:
One: The raw material manufacturer is required to provide a material certificate report.
Two: High-end products must require SGS material certification and send to relevant laboratories for material composition analysis to confirm whether the composition content meets the material requirements of the drawings.
3. During the non-destructive inspection of Hexagon Flange Bolt, if any part of the quenching cracks, wrinkles on the supporting surface and below are found, and whether the coating meets the Rosh environmental protection requirements.
4. For Hexagon Flange Bolt hardness level, do the corresponding hardness impact test; internal hardness, mechanical properties, torque test, etc. will damage the Hexagon Flange Bolt, but for the screw factory with a strong concept of quality, this is a must for testing .
