✅ Trusted by 30+ countries | ⏱ 10+ years export expertise | 🏭 Factory-direct pricing

🏭 50,000 sqm manufacturing base — Hebei, China

Price Markups of 40–60%

Multi-tier distributors add 3–5 layers of margin. A cylinder head cap screw that costs $0.08 at factory gate reaches you at $0.13–$0.15.

Inconsistent Quality

Batch-to-batch variation in hardness, thread accuracy, and black oxide finish leads to rework, field failures, and warranty claims.

Hidden Shipping Costs

Distributors often split shipments or use premium freight. Direct factory consolidation cuts shipping costs by 22–35%.

Lead Times of 8–12 Weeks

Most distributors don't stock deep. When you need 200,000 pieces of cap head wood screws black, they back-order — stalling your production line.

Compliance Headaches

Missing or forged CE, RoHS, or ISO documents can stop your goods at customs. 40% of import delays are fastener-related documentation issues.

🔹 What is the difference between cap head wood screws black and cylinder head cap screw?

Cap head wood screws black are designed for wood and composite materials — they feature a sharp point, aggressive thread pitch, and a black oxide coating for corrosion resistance and aesthetics. Cylinder head cap screw (also known as socket head cap screw) has a cylindrical head with a hex socket drive, used in metal-to-metal fastening where high tensile strength is required. Both are available in custom specifications.

🔹 What is your minimum order quantity (MOQ) for these fasteners?

For standard cap head wood screws black and cylinder head cap screw, our MOQ is 10,000 pieces per size. For custom OEM/ODM orders, MOQ is 50,000 pieces. We also offer sample orders (500–1,000 pcs) for qualification at cost price.

🔹 What payment methods do you accept for international buyers?

We accept T/T (bank wire transfer), L/C (letter of credit), and PayPal for smaller orders. For first-time buyers, we typically require 30% deposit and 70% balance against copy of shipping documents. Long-term contracts can negotiate open account terms (net 30/60) after 2–3 successful orders.

🔹 How do you ensure quality consistency across batches?

Every production batch undergoes spectrum analysis (material verification), hardness testing (Rockwell), tensile testing, thread gauge inspection, and salt spray test for black oxide finish. We provide a Certificate of Analysis (COA) with every shipment. Our defect rate is ≤0.3%, verified by SGS and TÜV.

🔹 What are your typical shipping costs and delivery times to the USA/Europe?

Shipping costs depend on order volume and destination. As a benchmark: a 20ft container (approx. 20–22 tons of fasteners) from Tianjin to Los Angeles or Rotterdam costs $1,800–$2,500 (sea freight, FOB). Delivery time: 18–22 days for production + 25–30 days sea freight. Express shipping (DHL/FedEx) for samples: 5–7 days.

🔹 Can you provide custom packaging with my brand?

Yes, we offer OEM packaging — your brand, your barcode, your labeling. Box sizes from 1kg to 25kg, or bulk pallet packaging. We also provide private label for cap head wood screws black and cylinder head cap screw with no minimum branding fee for orders above 100,000 pcs.

🔹 What after-sales support do you offer?

We provide 24-month warranty against manufacturing defects. If a batch fails to meet agreed specifications, we replace or refund at your choice. Our team is available via WhatsApp, email, and phone (English-speaking support). We also offer free technical consultation for fastener selection and application engineering.

🔹 Are your products compliant with EU and US regulations?

Absolutely. All our cap head wood screws black and cylinder head cap screw are CE-marked, RoHS-compliant, and REACH-compliant for the EU market. For the US, we meet ASME B18.2.1 and ASME B18.2.3.1M standards. We provide full documentation: Certificate of Origin, Packing List, Commercial Invoice, and Material Test Report with every shipment.
