Catalog density for buyers who count pieces

TwinPin Works, established 2003 in Dongguan, operates 8,500 m² of production floor with 200+ staff and 45 cold-heading lines. Annual capacity: 6,000 metric tonnes across DIN, ISO, and JIS standards—serving 300+ export accounts in 40 countries.

Certified to ISO 9001:2015 and IATF 16949, we supply metric fasteners and OEM kits with full heat-lot traceability. Every carton carries mill-lot cross-reference, coating batch ID, and PO fields sized for overseas receiving docks.

PPAP Level 3 documentation, ASTM B117 salt-spray coating maps, and moisture-barrier export packing are standard for every container—not optional add-ons negotiated after award. Buyers who count pieces get a desk that looks like a plant catalog, not a brochure.
