Screw Customer Visit with ISO Standard Manufacturing Production Process
Customer Visit at Our Screw and Bolt Manufacturing Factory – Real-Time Quality You Can Trust


Today, we welcomed a valued international customer to our screw and bolt manufacturing facility in Zhongshan, China. The visit included a full tour of our production line, from raw material inspection and cold heading, to thread rolling, heat treatment, and final packaging. Our client had a chance to closely observe how we manufacture high-strength Grade 8.8 bolts and ISO standard combination screws under strict quality control.
During the visit, we demonstrated how each process is guided by our in-house SOPs and international standards like ISO 898-1 and DIN 933. Our engineers explained the material traceability system, real-time inspection routines, and the importance of heat treatment in achieving mechanical performance.
These on-site factory visits help build customer confidence and long-term cooperation. When buyers see the production with their own eyes, they understand the difference between low-cost fasteners and precision screws designed for global markets.
At Taiming, we don’t just deliver bolts—we deliver trust, backed by factory transparency and manufacturing discipline.
