To ensure stable quality ,our factory execute strictly quality inspection standard:
1. do raw material spectral analysis to verify steel grade
2. do random hardness test after heat treatment to meet required strength class
3. do tensile and shear load testing to verify ultimate load capacity
4. do thread gauge inspection to ensure smooth assembly with matched nuts
5. do visual and dimensional sampling inspection,including shank diameter, length, hex head thickness and thread tolerance control
