How to Source Fasteners from China
A practical guide for buyers, distributors, contractors, and OEMs who want to source fasteners from China and want to do it well.
Why China for fasteners
China produces a substantial share of the world's fasteners — roughly half by volume. Within China, the production is concentrated in a small number of geographic clusters. The largest is Yongnian District in Handan, Hebei; others include Haiyan in Zhejiang, Wenzhou, and parts of Guangdong. Each cluster has its own product specialties and competitive position.
Yongnian, where HDBolt is based, focuses on bolts, nuts, threaded rods, and anchors — the heavy-end commodity fasteners used in construction, infrastructure, and industrial equipment. Haiyan and Wenzhou tend to specialize in screws and lighter precision fasteners.
Direct from factory vs. through a sourcing partner
Both are legitimate paths. The right choice depends on your volumes, product mix, and how much time you can spend on supply chain management.
Going direct to a factory works when…
- You buy large quantities of a narrow product range (one or two SKUs in container quantities).
- You have time to maintain the factory relationship — payment terms, production scheduling, quality issue resolution.
- You can travel to China occasionally or have someone you trust in-country.
Going through a sourcing partner works when…
- You buy a varied product mix that no single factory can supply.
- You need pre-shipment quality inspection that isn't built into your operation.
- You want consolidated container loading mixing many suppliers' products.
- You don't want to manage 5–10 supplier relationships per shipment.
MOQ — Minimum Order Quantity
MOQ varies enormously by product and factory. As a rough guide:
- Commodity hex bolts/nuts (DIN 933, DIN 934): 500–1000 kg per size from most factories; 100–200 kg if buying through a sourcing partner who consolidates from stock.
- Drywall and chipboard screws: 1 carton (typically 25 kg) per size in stock; 1000+ kg for production runs.
- Custom drawings: 5000–10,000 pieces typical, sometimes lower depending on complexity.
- Stainless or specialty grades: Higher MOQ than carbon steel — material is more expensive to commit.
Lead times
- Stock items: 3–7 days to ship from the factory; 7–15 days to load a container including consolidation.
- Production-to-order, standard products: 15–30 days production + container loading.
- Custom drawings: 30–45 days typical, including tooling preparation.
- Sea freight transit: 25–35 days to U.S. East Coast, 18–25 days to U.S. West Coast, 30–45 days to Europe, 12–18 days to Southeast Asia.
Quality control
The single most important point: have a defined inspection process before goods leave China. This is not optional. Even from a good factory, things go wrong — wrong size mixed in, plating defects, packaging damage, mislabeling.
A reasonable pre-shipment inspection covers:
- Random sampling per AQL (typically AQL 1.5 for major defects, 4.0 for minor).
- Dimensional check with calipers and thread gauges.
- Surface finish visual check (zinc plating thickness, coating coverage).
- Packaging verification (carton weights, labels, master carton count).
- Photographs of representative samples and any defects found.
- Mill Test Certificates (MTC 3.1) for any structural or specification-grade material.
Payment terms
Standard practice for international fastener trade:
- 30% T/T deposit, 70% before shipment — most common for new customers and standard production orders.
- 30% deposit, 70% against B/L copy — slightly more buyer-friendly, common after first successful order.
- L/C at sight — for larger orders or first-time arrangements with good documentation control.
- OA (open account) 30/60/90 — only after established relationship and credit assessment.
Common mistakes to avoid
- Buying on lowest price alone. The lowest quotation is often from a factory cutting material grade, plating thickness, or both. Compare like-for-like specifications.
- Skipping pre-shipment inspection. Resolving issues after the container arrives at your warehouse is 10× more expensive than catching them in China.
- Believing the factory profile. Many "factories" on B2B marketplaces are trading companies with rented offices. Verify with video calls, business licenses, and cross-checks.
- Not specifying packaging. Factories will use the cheapest packaging unless you specify. Confirm carton size, weight, master carton count, labeling, and pallet requirements.
- Insufficient documentation. Always require commercial invoice, packing list, B/L, MTC where required, and Certificate of Origin. Missing documents at port of arrival cause expensive delays.
How HDBolt fits in
If you've read this far, you've already done more sourcing homework than 80% of buyers. HDBolt is built to handle the operational details for buyers who'd rather focus on their own customers.
We're not the cheapest option in absolute price terms — direct-from-factory always wins on unit price for stocked items. We're competitive on total landed cost when you factor in the time, errors, and quality issues we prevent. For buyers with mixed-product orders, periodic shipments, or specifications that need verification, the math typically works out in our favor.
