Engineered for
the industries that build the world.
Every INTAFIX fastener is specified against the load, corrosion, and vibration profile of the environment it lives in. Select your sector to see the fastener families, standards, and coatings we recommend — with real project references.
Six sectors.
Six specification playbooks.
Each sector has its own compliance regime, corrosion environment, and delivery cadence. We built dedicated engineering teams around each.

Oil, Gas & Offshore
NACE MR0175-compliant fasteners for splash-zone, downhole and topside assemblies. Duplex 2205, Super Duplex 2507, Inconel 625, and Xylan-coated B7M studs.

Wind & Renewables
Structural bolts for tower flanges, hub bolts, and blade attachments. HV-preloaded assemblies to EN 14399 with 3.1 mill certs and PT documentation.

Heavy Steel Construction
ASTM A325 / A490 structural bolts, TC assemblies, and post-installed anchors for high-rise and industrial framing. ICC-ES ESR-listed anchors.

Automotive Assembly
IATF 16949 supply. PPAP Level 3 documentation. Torque-to-yield fasteners, JIS B1189 flange bolts, and specialty aluminum-to-steel joining screws.

Rail & Transit
Rail clip fasteners, sleeper screws, contact-line hardware, and rolling stock structural bolts. EN 15085 welded-frame compliance where required.

Mining & Extraction
Roof-bolts, crusher fasteners, conveyor belt hardware. Impact-rated Grade 12.9 with vibration-resistant patch coatings. High-abrasion service.

"We audit fastener suppliers every 18 months. INTAFIX has failed zero of the last four audits — a stat I can't say about any other supplier we run. Their Ningbo line is basically a German plant that happens to be in China."
