How We Respond
Dedicated KS-compliant line
Separate from general industrial stock, we operate a dedicated line manufactured and controlled in full compliance with KS standards.
Bidirectional traceability
From a shipped product we can trace back to the raw material coil and its supplier, allowing us to respond to material verification requests.
Lot-based certificates
Test certificates are issued only from the inspection data of the lot actually delivered.
53 years of continuous production
We have operated in fasteners as a single product category since 1973.
