We see every screw as part of the customer’s equipment rather than an isolated component. Our engineers pay attention to how the part fits, carries load, withstands repeated assembly and remains consistent in repeat production. When a design presents a manufacturing or reliability risk, we discuss it openly and work with the customer on a practical improvement before volume production.
Shi Shi Tong has served more than 8,678 customers, with an 87%+ repeat-purchase rate and more than 56% of new business coming through customer referrals. The company is ISO 9001 certified and can provide material certificates, dimensional inspection records, salt spray or hardness test records, and batch traceability documents when required.
