About Us

At SINOFASTENER, we don't just sell fasteners.
We make sure every single one performs — so you don't have to worry.

OUR STORY It started in 1990 — a small fastener workshop in Ningbo, China.
Thirty-five years later,
SINOFASTENER supplies clients in over 80 countries.
But the most important chapter of our story is being written right now.
For 35 years,
we've listened to the real concerns of engineers and procurement managers sourcing from China:
"Can I trust this batch actually meets spec?"
"If something goes wrong — who takes responsibility?"
"How exactly should these bolts be installed — and who can tell me?"
The industry's answer has always been: Trust your supplier.
Spot-check a few samples.
Then hope for the best.
We decided that isn't good enough.
In 2026, SINOFASTENER began a fundamental transformation — from a traditional fastener trader into a Quality Assurance Platform.
The foundation of this transformation:
Our own CNAS-certified laboratory (ISO/IEC 17025, in preparation).
Every batch is tested in our lab before it leaves our facility.
We don't ask you to trust us. We ask you to trust the data.
