About Dashitou · 大石头

English working mark: Dashitou / Big Stone Fastener. Legal trading entity for this enquiry site: Ningbo Dashitou Hardware & Electromechanical Trading Co., Ltd. (宁波市大石头五金机电商贸有限公司). Niche lock: stone cladding, structural steel, and heavy-duty site fixings — RFQ and drawing handoff, not a retail grid or screws→bolts→nuts warehouse catalog.

Who we are

Dashitou is the overseas B2B enquiry face for project fasteners matched to an install node. On this site we publish series, applications, and buyer-prep guides so your first email already carries the fields we confirm before quote.

  • Trading entity (on-site) — Ningbo Dashitou Hardware & Electromechanical Trading Co., Ltd. (宁波市大石头五金机电商贸有限公司).
  • Manufacturing relationship — Open: how production capacity is contracted or attributed is confirmed in enquiry; this page does not claim a self-owned “super factory” workshop, plant area, headcount, or platform rankings.
  • Not this site — we do not mirror a generic stainless screw/bolt/nut warehouse directory or paste another brand’s factory card metrics onto About.

Who we serve

Overseas project buyers, fabricators, stone and façade contractors, structural steel shops, and importers who need fasteners matched to a node — not a shopping cart. Typical jobs sit in three lanes:

  • Stone / cladding — panels, soffits, stone-on-steel brackets, undercut-style programs when the print calls for them.
  • Structural — frames, gussets, and connection plates where bolt class and coating follow the controlling drawing.
  • Heavy — plant baseplates, high-bearing joints, and site fixings where heavy hex and high-load anchors are routine.

Series stubs live on Products (wedge · chemical accessories · structural bolts · heavy hex · cladding · stone). Datasheets and drawings follow enquiry.

What we confirm before a quote

Desk checks — not marketing claims:

Print or field notes

Dimensioned drawing, CAD, or clear sketch with revision — or enough fields to open a review. Drawing handoff.

Qty band & use

Discussion band and target use or buyer standard note. Field list: RFQ checklist.

Until those are aligned, we do not treat a number as final. Samples, packing, and private-label marking follow the same thread. Contact sequence: 01 receive · 02 add drawing · 03 confirm before quote.

Honest documents policy

We do not invent ISO, CE, IATF, plant area, headcount, capacity figures, client logos, or ranking badges on this site. Applicable datasheets, packing formats, and project documents are shared privately when they matter to the RFQ. Catalog PDF is TBD — request files with your enquiry.

Downloads

Catalog PDF — TBD. Until ready, request datasheets and drawings with your RFQ. Prepare fields first with Guides.
