What is the minimum order quantity for custom hardware and fasteners?

Confidence 4/5 Established practice · review by 2026-12-31

Minimum order quantity for custom hardware and fasteners from China:

10,000+ pieces for a cold-formed or headed custom fastener, because the dies are cheap but the set-up is per-run and the machines run fast. Standard parts in stock have no meaningful minimum.

What goes wrong with custom hardware and fasteners

  • Specifying a finish by appearance instead of by standard, then getting a coating that fails in salt spray.
  • Accepting a lower stainless grade without noticing.
  • Not specifying thread tolerance and discovering the parts do not mate.
  • Assuming standard parts are always available; Chinese "standard" dimensions sometimes follow GB rather than DIN or ANSI.
  • Ignoring anti-dumping exposure on fasteners.
