๐จ Are You Overpaying for Critical Fasteners?
Traditional distributors add 30-50% markup on standard fasteners. For a mid-volume buyer purchasing 50,000 units annually, this translates to over $15,000 in unnecessary costs. You need factory-direct pricing, not middleman margins.
Inconsistent heat treatment and loose tolerances in jack screw bolt flanges lead to stripping, cracking, and catastrophic equipment failure. A single production line shutdown can cost $10,000 per hour in downtime.
Complex logistics from unreliable suppliers result in split shipments, demurrage charges, and lead times exceeding 8-12 weeks. This forces you to keep excessive safety stock, tying up working capital and storage space.

"We switched to Boen for our floor flange screws and saw an 18% reduction in total cost of ownership within the first quarter. Their quality control is exceptional, and the factory-direct pricing saved us over $20k annually."
"The jack screw bolt flange assemblies from Boen are the most reliable we've tested. Their 10.9-grade alloy steel handles our 150-ton press loads without deformation. Lead times are consistently under 3 weeks."
Your sourcing questions answered by our technical team.
Our standard range for floor flange screws (DIN 6923) spans from M6 to M30. We also offer custom sizes up to M48 for heavy-duty industrial applications. The most common sizes requested by our US and European clients are M12, M16, and M20 with coarse threads.
A jack screw bolt flange (DIN 6330) is specifically designed for leveling, adjustment, and heavy jacking applications. It features a longer shank and a thicker, hardened washer face to distribute high compressive loads. Standard flange bolts are primarily for structural clamping, not dynamic adjustment.
Absolutely. We specialize in OEM/ODM design. We can customize head markings, thread lengths, coatings (Geomet, Dacromet, HDG), and even design entirely new bolt configurations based on your engineering drawings. Minimum order quantity is typically 5,000 pieces for custom runs.
We follow a strict 3-step QA process: 1) Incoming raw material inspection (chemical composition & hardness). 2) In-process inspection (dimensional checks, thread gauging). 3) Final inspection (tensile testing, salt spray test, surface defect check). We provide Material Test Reports (MTR) with every shipment. Our facilities are ISO 9001 compliant.
We offer FOB (Tianjin Port), CIF, and EXW terms. Standard lead time for stock sizes is 15-20 days. For OEM orders or custom sizes, lead time is 25-30 days. We partner with major freight forwarders (Maersk, COSCO) to ensure reliable shipping to the USA, Germany, UK, and all major European ports.
Yes, we provide free samples to qualified buyers. You only need to cover the shipping cost. We recommend testing our jack screw bolt flange under your specific load conditions to validate performance. Request your sample via the form below or email us directly.
For standard floor flange screws and bolt flanges, our MOQ is typically 2,000 pieces per size. For mixed sizes or standard stock items, we can be flexible. Please contact our sales team to discuss your specific volume requirements.
Our factory-direct model eliminates 2-3 layers of distribution. On average, we offer 30-40% cost savings compared to US and European distributor prices, even after shipping and duties. We are transparent about our pricing structureโno hidden fees.

Rafael Silva
Operations Manager, Brazil
"We were skeptical about switching suppliers, but Boen's jack screw bolt flanges arrived earlier than expected and the quality was superior to our previous European supplier. The cost savings were 35%."

Sarah Chen
Supply Chain Manager, Singapore
"The floor flange screws are consistently within tolerance. We appreciate the detailed MTRs and the responsive after-sales service. It's rare to find such professional communication from a factory."

David Mรผller
Technical Director, Germany
"We conducted a 3-month pilot test on Boen's heavy-duty fasteners. The tensile strength and durability exceeded our requirements. They are now our approved supplier for all structural bolting."
