🔧 “Thread pitch mismatches on M14 1.50 flange bolts shut down our assembly line for 3 hours.”

— Production Supervisor, German Automotive Tier 2 Supplier

💰 “We were paying 40% more for M14 2.0 flange bolts from a European distributor – same specs, but no traceability.”

— Procurement Manager, UK Agricultural Machinery OEM

📦 “Minimum order quantities were killing our cash flow – 50,000 pieces when we only needed 5,000.”

— Supply Chain Lead, US Construction Equipment Distributor

🔩 “The M14 1.5 x 30mm flange bolts from our last supplier had inconsistent flange height – caused joint loosening after 200 cycles.”

— Quality Engineer, Asian Automotive Parts Manufacturer

“We switched our entire M14 flange bolt procurement to Boen. 24% cost reduction, zero non-conformance in 6 months. Their M14 1.5 x 30mm bolts are now our standard.”

— Thomas K., Procurement Director, German Agricultural Machinery Co.

“Boen's PPAP Level 3 documentation and 15-day lead time on M14 2.0 flange bolts helped us meet a critical project deadline. Exceptional quality.”

— Maria S., Supply Chain Manager, US Construction Equipment OEM

The M14 1.5 x 30mm flange bolt has a fine thread pitch (1.5 mm) and a 30 mm length under head – ideal for applications requiring precise clamping force and vibration resistance. The M14 2.0 flange bolt has a coarse thread (2.0 mm) for faster assembly and better performance in softer materials. The M14 1.50 flange bolt is dimensionally identical to the 1.5 variant but often specified for aftermarket or legacy equipment. Boen Fasteners stocks all three variants in multiple grades and coatings.

Absolutely. As an OEM/ODM maker, we offer fully customizable M14 flange bolts – lengths from 10 mm to 150 mm, hex/TORX®/socket drives, and coatings including zinc plating, HDG, Dacromet®, Geomet®, and black oxide. Minimum order quantity: 500 pieces for custom specs.

All our flange bolts are manufactured under ISO 9001:2015 quality management system. We also provide CE, RoHS, and IATF 16949 (upon request). Each shipment includes material test certificates, dimensional inspection reports, and hardness test data – fully traceable back to the production batch.

Standard production: 15–25 days for orders up to 500,000 pieces. Express (air): 5–7 days via DHL/FedEx for urgent orders. Shipping costs are calculated based on weight and destination – we offer FOB Tianjin, CIF major ports, and DDP options. Contact us for a real-time shipping quote.

We follow a 3-stage quality control process: (1) Incoming raw material inspection (chemical composition + hardness), (2) In-process dimensional checks (thread pitch, flange diameter, head height) at every 500 pieces, (3) Final random sampling per ANSI/ASQ Z1.4-2023. We also offer PPAP Level 3 for automotive and defense clients.

For standard sizes (M14 1.5 x 30mm, M14 1.50, M14 2.0), our MOQ is 1,000 pieces per size. For custom specifications (special coatings, drives, or lengths), the MOQ is 500 pieces. We welcome sample orders (50–200 pieces) for pre-production qualification – samples are free, you pay only shipping.

Yes. We provide full after-sales technical support – including installation guidance, torque specification recommendations, and failure analysis if needed. All orders come with a 12-month warranty against manufacturing defects. Our team responds within 4 hours during business hours (GMT+8).
