We build the fasteners
that hold the world together.
Since 1998, INTAFIX has manufactured high-integrity fasteners for the engineers who cannot afford to fail. From Baghdad to Berlin, our screws are torqued into wind turbines, oil rigs, subway tunnels, and Airbus jigs — quietly, precisely, and to spec.
Founded on one
simple rule.
Every fastener holds.
INTAFIX began in 1998 in a 400 m² workshop outside Beijing, with three cold-heading presses and a single client — a German scaffolding manufacturer who could not tolerate a single failed screw across 40,000 units per week. Twenty-seven years later, that obsession still runs the company.
Today, INTAFIX manufactures and distributes over 10,000 SKUs of industrial fasteners from 17 production sites, serving customers in construction, oil & gas, renewable energy, automotive, rail, and mining across 20+ countries. We are a division of INTAZIA International Industrial Solutions, headquartered in Beijing with regional operations in Houston, Stuttgart, Dubai, and Ningbo.
We are not the cheapest fastener supplier on the market. We are the one your engineering team calls when the drawing says "no substitution permitted."
27 years of engineered trust.
From a single workshop to a four-continent manufacturing network. The milestones that shaped how we build, test, and ship every INTAFIX product.
Founded in Beijing by Wei Zhang. First 3 cold-heading presses installed.
ISO 9001 certified. First OEM contract signed with a German scaffolding maker.
Ningbo plant opens (12,000 m²). Bi-metal self-drilling line commissioned.
IATF 16949 for automotive supply. Stuttgart office opens for EU customers.
Houston office & US warehouse. NACE MR0175 program launched for oil & gas.
Planned: automated micro-lot line — sub-500-unit MOQ for R&D partners.
Three operating principles.
The philosophy that governs everything from our raw-steel purchasing to how we answer an RFQ email.
The drawing is the contract.
If the drawing calls for Grade 12.9, we ship 12.9. Not 10.9 with a paperwork upgrade, not "equivalent" from a substitute alloy. Every heat is verified before it enters our line.
We test everything, every batch.
Hardness. Tensile. Salt spray. Torque-tension. Dimensional. Every batch. No sampling. If a lot fails one test, the entire lot is scrapped — never repackaged.
Full traceability, forever.
Every INTAFIX pallet ships with an EN 10204 3.1 mill test report tied to the heat number. If a fastener fails in the field, we can identify the exact shift and press it came from — in under 20 minutes.
The people behind
every torque spec.
A team of metallurgists, mechanical engineers, and operators. Combined, our leadership brings 140+ years of fastener manufacturing experience.
Wei Zhang
"Fasteners are the last thing anyone thinks about — until one of them fails."
Markus Köhler
"We run our plants the way an aerospace shop runs. Everything measured, everything tracked."
Dr. Lin Hao
"Steel does not lie. If we treat it right, it does exactly what we tell it to."
Sara Al-Rashid
"Our job is to make the customer's engineering team feel like we already work for them."
Four continents.
One quality standard.
Regional offices for commercial response. Manufacturing consolidated where we can control it end-to-end. Warehouses positioned so no customer waits more than 14 days for a stock order.
