🔴 Inconsistent Quality

One batch fails torque tests, the next doesn't. 43% of production stoppages trace back to substandard fasteners. (Industry Benchmark Report 2025)

🔴 Hidden Supply Chain Costs

Broker markups, split shipments, and emergency air freight add 22–35% to the landed cost of imported fasteners.

🔴 Long Lead Times

Standard lead times of 8–12 weeks disrupt JIT manufacturing. 67% of Ops Managers say fastener delays caused missed delivery targets.

🔴 Certification Gaps

Missing CE, RoHS, or ICC-ES reports can void insurance and shut down job sites. 1 in 5 suppliers fail compliance audits.

🔴 Poor Technical Support

Need a custom thread or coating? Most suppliers can't engineer beyond catalog specs. 78% of buyers want a partner, not just a price list.

Factory-Direct Pricing

Eliminate 2–3 layers of intermediaries. Our galvanised button head screws and hex round head screw products are priced at 15–30% below distributor levels.

"We switched to Boen for our galvanised button head screws. Lead time dropped from 10 weeks to 3 weeks, and we saved €47,000 in the first year."

— Thomas Müller

Procurement Director, AgriParts GmbH, Germany

"The hex round head screw quality is consistent batch after batch. Their PPAP documentation saved us 3 weeks of auditing."

— Sarah Chen

Supply Chain Manager, ElectroMotive Inc., USA

"Boen's factory-direct pricing gave us a 28% cost advantage over our previous distributor. And the ZnNi coating is outstanding."

Q1: What is the difference between a galvanised button head screw and a hex round head screw?

A galvanised button head screw has a low-profile domed head with a cross or hex drive, ideal for applications where a smooth finish and corrosion resistance are needed. A hex round head screw features a six-lobed recessed drive (Allen key) with a larger bearing surface, offering higher torque transfer for structural and mechanical assemblies. Both are available in hot-dip galvanised or electro-galvanised finishes.

Q2: What is the minimum order quantity (MOQ) for custom sizes?

Our standard MOQ is 1,000 pcs per size for standard galvanised button head screws and hex round head screws. For custom dimensions, coatings, or drive types, the MOQ is typically 5,000 pcs. We offer tiered pricing for larger volumes.

Q3: Do you provide certificates of compliance and material test reports?

Yes. Every shipment includes ISO 9001:2015, CE, RoHS, and a Material Test Certificate (MTC) with batch traceability. We also provide ICC-ES reports, salt spray test results, and PPAP Level 3 documentation upon request.

Q4: How long does shipping take to the USA and Europe?

Sea freight: 20–30 days to major ports (Los Angeles, Rotterdam, Hamburg). Air freight: 5–8 days. DDP (Delivered Duty Paid) express: 10–12 days door-to-door. We handle all customs clearance.

Q5: Can you match the coating color of my existing fasteners?

Absolutely. We offer custom color matching for RAL and Pantone codes. Our ZnNi and Dacromet coatings can be tuned to specific color and gloss levels. Send us a sample and we will match it within 5 business days.

Q6: What payment methods do you accept?

We accept T/T (bank transfer), L/C (letter of credit), PayPal, and Alibaba Trade Assurance. For first-time buyers, we recommend 30% deposit + 70% balance against copy of shipping documents.

Q7: Do you offer free samples for evaluation?

Yes! We provide free samples (up to 10 pcs) for qualified buyers. Simply cover the shipping cost. Request your samples through the form below or contact our team directly.

Q8: How do I get started with a bulk order?
