Stress Rupture Above 600°C

Standard 316 stainless steel fasteners lose over 70% of tensile strength at 650°C. A286 alloy maintains >85% of its room‑temperature strength up to 700°C.

Inconsistent Heat Treatment

Many suppliers skip solution annealing & precipitation hardening. Result: batch‑to‑batch hardness variation of up to 15 HRC. Our process ensures ±2 HRC consistency.

Hidden Logistics & Tariff Costs

Importing from multiple vendors increases freight, customs brokerage, and risk of delays. Factory‑direct consolidation cuts logistics overhead by 22–35%.

Missing Compliance Documentation

Aerospace & energy buyers need full material traceability (EN 10204 3.1/3.2). Without it, your QA team spends weeks validating each shipment.

Factory‑Direct Pricing

Eliminate 3–4 layers of middlemen. Our pricing is 15–25% lower than distributors while maintaining higher quality control.

Full Metallurgical Lab

In‑house tensile testing, hardness (HRC), impact, and SEM analysis. Every batch gets a digital certificate of analysis.

"The A286 socket head cap screws from Boen consistently meet our NAS spec. Their batch traceability documentation is the best we've seen from any Asian supplier."

— David K.Procurement Manager, US Aerospace Components

"We switched our M10 button head screw supply to Boen. Lead time dropped from 6 weeks to 18 days, and we saved 23% on landed cost."

— Elena V.Supply Chain Director, German Automotive GmbH

"Their factory audit was spotless. Real in-house testing, clear workflows, and a team that actually understands high-temp alloy requirements."

— Raj P.Technical Director, UK Energy Systems Ltd.

A286 is an iron‑based superalloy (AMS 5731) that retains high tensile strength up to 700°C, whereas 18-8 (304) stainless steel loses significant strength above 300°C. A286 also offers superior creep resistance and oxidation resistance, making it the standard for aerospace, energy, and high‑performance automotive applications.

Yes. We offer Xylan 1420, Everlube 620, and silver plating on all A286 m10 button head screw orders. These coatings reduce friction during assembly and provide additional corrosion protection in salt‑fog environments (tested per ASTM B117).

Standard MOQ is 500 pieces per size. For custom lengths, drive types, or coatings, MOQ may be 1,000–2,000 pieces. We also offer sample orders (10–50 pcs) for qualification testing — contact us for a sample quote.

Absolutely. Every shipment includes an EN 10204 3.1 mill certificate with traceable heat numbers, chemical composition, and mechanical properties. 3.2 certificates (third‑party inspection) are available upon request at a nominal fee.

We ship FOB Tianjin / Shanghai or CIF / DDP to major ports. Delivery time: 12–18 working days for standard production, plus 15–25 days ocean freight to US West Coast or Rotterdam. Air freight (3–5 days) is available for urgent orders.

Yes. Our engineering team has 15+ years of experience in custom fastener design. Send us your drawing, torque requirements, and environmental conditions — we'll provide a free design review and a quotation within 48 hours.

We accept T/T (30% deposit, 70% before shipment), L/C at sight, and PayPal (for samples only). For established customers, we can offer net‑30 terms after 3 successful orders. All payments are processed through our verified corporate bank account.

"A286 socket head cap screws arrived earlier than quoted." The chemical and mechanical certs were perfect. We use them on our turbine overhaul line. No issues whatsoever.

"Best M10 button head screw supplier we've worked with." Consistent quality, clear communication, and they helped us optimize the packaging for our assembly line. Highly recommend.

Finally, a factory that understands high‑temperature fasteners. Their technical team helped us select the right coating for our exhaust application. Saved us months of testing.

Price + quality + speed = unbeatable. We compared quotes from 5 suppliers. Boen offered the best value and their lead time was 2 weeks faster than the nearest competitor.
