Distributors often add 35–50% markup. For high-volume double ended bolt orders, that erodes your competitiveness.

Galling, uneven threads, or wrong pitch cause assembly delays. One rejected batch can halt a production line for days.

Many suppliers quote 45–60 days. With volatile freight, you never know actual arrival — until it’s too late.

Missing CE, RoHS, or ISO documentation creates customs holds and liability risks. Buyers need full traceability.

One supplier for Europe, another for the US — different packaging, docs, and incoterms. It drains your procurement team.

Most stockists only offer standard sizes. If you need custom length, thread, or material for a double sided bolt, you’re forced into expensive small-batch machining.

Factory-Direct Power

Eliminate intermediaries. Save 18–30% vs. distributor prices on double ended bolt bulk orders.

Quality Assurance

ISO 9001, CE, RoHS. 100% thread inspection, tensile testing, and salt spray report with every batch.

High-Speed Delivery

Standard lead time 15–25 days. Express air freight available for urgent double sided bolt orders.

OEM/ODM Customization

Custom thread pitch (UNC, UNF, metric), length, material (carbon steel, SS304, SS316, alloy), and coating.

Global Logistics

FOB, CIF, DDP — we handle documentation, customs, and multi-region compliance (EU, US, SEA).

Full Traceability

Heat number, mill cert, batch number — every double ended bolt is traceable from raw material to shipment.

Agricultural Machinery

Double ended bolts used in harvester frames, tillage equipment, and irrigation systems. Demands high corrosion resistance.

Automotive & Trailer

Suspension links, crossmembers, and axle fastening. Grade 10.9 double sided bolt for high shear loads.

Construction & Structural

Steel beam connections, scaffolding, anchor systems. Hot-dip galvanized double ended bolt for outdoor durability.

“We switched our double ended bolt supply to Boen and cut 22% per unit while maintaining grade 10.9. Their QC documentation is excellent.”

“Custom double sided bolt with M20x1.5 thread, 480mm length — delivered in 18 days. Perfect for our agricultural line.”

“Consistent quality across 6 container shipments. Boen’s factory-direct pricing and fast response make them a top-tier supplier.”

A: In industrial practice, the terms are often interchangeable. A double ended bolt typically has threads on both ends with an unthreaded middle section. A double sided bolt may refer to fully threaded studs. Both are used for fastening components where a nut is applied on each side. We manufacture both types per your specification.

A: Carbon steel (4.8, 8.8, 10.9), stainless steel (SS304, SS316, SS316L), and alloy steel. We also offer hot-dip galvanized, Dacromet, and PTFE coatings. Grade 10.9 is common for automotive and structural applications.

A: Absolutely. We support OEM/ODM with custom thread pitch, length (up to 3000 mm), partial or full thread, and both metric and inch standards. Send a drawing or sample for a precise quote.

A: ISO 9001:2015, CE, RoHS, FCC, UKCA. We also provide mill test reports, batch traceability, and third-party inspection (SGS, TÜV) upon request. Our products comply with ASTM, DIN, and ISO standards.

A: Standard production 15–25 days. Express (air freight) 7–10 days. We ship via FOB Tianjin, CIF, or DDP to your door. We handle all customs documentation.

A: For standard sizes, MOQ is 500 pcs. For custom dimensions, MOQ is 2000 pcs. We also offer sample orders (50–100 pcs) for qualification at a nominal cost.

A: We follow a 3-stage QC: incoming raw material inspection, in-process thread and dimensional check, and final random sampling per AQL 2.5. Every batch is traceable to heat number.

A: Yes, we provide free samples for standard sizes (you pay shipping). For custom samples, a small tooling fee applies, refundable with bulk order. Contact our sales team to arrange.

Lars J. Procurement, Sweden

“We ordered 20,000 pcs of double ended bolt grade 8.8 for our trailer assembly. The thread quality is consistent, and the zinc coating passed 72h salt spray. Price was 18% lower than our previous supplier. Will repeat.”

Emily T. Supply Chain, USA

“Boen’s team helped us design a custom double sided bolt for a solar mounting system. The thread accuracy and mechanical properties were exactly as specified. Lead time was 20 days, including custom coating.”

Ravi K. Operations, India

“We were struggling with high shipping costs from other suppliers. Boen’s factory-direct pricing and DDP shipping saved us 31% on total landed cost. The double ended bolts are top-notch.”

Claudia M. Engineering, Italy

“Excellent technical support. We needed a non-standard thread length for a double sided bolt, and Boen’s engineers proposed a solution that reduced material waste by 12%. Great partner.”

Hiroshi N. Director, Japan

“We have been sourcing double ended bolts from Boen for 2 years. Their delivery reliability is over 98%, and the batch-to-batch consistency is impressive. Highly recommended for volume buyers.”

Ahmed S. Procurement, UAE

“Fast response, clear communication, and the product quality exceeded our expectations. The double ended bolt samples arrived in 5 days. We placed a container order immediately.”
