At CAP BOLT LTD, we understand that in the world of fasteners, a single point of failure is not an option. Our quality assurance protocol is designed to provide you with total peace of mind through two rigorous layers of verification:

Third-Party Validation (SGS Certified): Every batch of our products undergoes comprehensive testing by SGS, the world's leading testing and certification body. From material chemical analysis to mechanical property testing (Tensile, Hardness, Salt Spray), our SGS Reports ensure full compliance with international standards (ASTM, DIN, ISO).

100% Optical Sorting Services: To meet the demands of automated assembly lines, we utilize state-of-the-art High-Speed Optical Sorting machines. Using high-resolution CCD cameras, we filter out dimensional deviations, thread defects, and foreign materials with micron-level precision.
