OEM/ODM Precision Titanium Fasteners Supplier & Exporter for the North Korea Market

For purely corrosive environments involving wet chlorine, dilute organic acids, and aggressive marine brine without severe mechanical shear, commercially pure Grade 2 titanium is recommended due to its superior ductility, weldability, and corrosion resistance. Conversely, when the fastener serves as a structural joint subject to high torque, tensile stress, and dynamic fatigue (such as cylinder heads, manifold studs, wheel hubs, or heavy gearbox mounts), Ti-6Al-4V Grade 5 (TC4) is mandatory. Grade 5 provides high yield strength (≥828 MPa) comparable to 10.9 high-tensile steel while eliminating rust.

Yes. We routinely manufacture fasteners strictly compliant with DIN (such as DIN 912 socket head, DIN 6921 flange hex, DIN 7991 countersunk), ISO, and ASME/ANSI standards. Furthermore, for regional industrial retrofits and legacy heavy equipment, our CNC tooling centers can machine precise metric fine threads, trapezoidal profiles, and Russian GOST specification threading from custom 2D drawings (DWG, DXF, PDF) or 3D STEP models.

Every production lot undergoes rigorous multi-tier inspection: (1) Incoming Material Testing: Chemical composition spectroscopy (O, N, H, Fe, C, V, Al content) and mechanical tensile testing from the Baoji Titanium Valley supply chain; (2) In-Process CMM & Profile Projector Checks: Strict dimensional monitoring during 5-axis CNC machining and thread rolling; (3) Final Batch Testing: 100% Go/No-Go thread fit validation, surface roughness (Ra) verification down to 0.4 μm, and batch-coded EN 10204 3.1 Material Test Certificates (MTC) supplied with the shipping documentation.

For bespoke engineered prototypes or critical non-standard components (such as CNC milled titanium brake rotors or complex manifold studs), our prototype MOQ starts as low as 10 to 50 pieces. For standardized titanium bolts, flange nuts, and Torx screws, standard production batch MOQ is typically 100 to 500 units. Prototype sample machining is completed within 5–7 business days, with full-scale production runs fulfilled within 15–20 days.

Because titanium can be susceptible to galling when threaded against titanium under high torque, we provide specialized surface treatments: (1) Physical Vapor Deposition (PVD): Hard wear-resistant TiN (titanium nitride) or TiAlN coatings delivering surface hardness up to HV 2500 in various industrial finishes; (2) Micro-arc Oxidation (MAO) & Type II Anodizing: Creating a ceramic-like anti-wear insulating surface; (3) Precision Mirror Polishing: Reducing micro-asperities to prevent friction lockup in manifold and exhaust installations.

Precision threads are individually protected using high-density poly-mesh netting or segmented PVC bubble trays to eliminate metal-to-metal contact. Shipments are packed into sealed moisture-barrier bags with desiccant gel packs, nested in heavy-duty export corrugated boxes, and strapped onto fumigated export wooden pallets or plywood crates suitable for land rail freight and maritime ocean transit.
