Manufactured directly from certified titanium bar stock using high-precision multi-axis CNC machines and wire EDM. Threading, surface finishing, and tolerances meet strict international quality guidelines.
Velnora Titanium Industry Co., Ltd. operates in Baoji City — recognized as China's Titanium Valley. Since 2013, our dedicated engineering team has manufactured precision fasteners and special metal components for global B2B clients.
Equipped with high-precision turning-milling centers, Swiss-type automatic lathes, and precision wire EDM machines capable of achieving strict dimensional tolerances down to ±0.01 mm on Gr5 titanium bar stock.
Every fastener batch is checked with Go/No-Go thread plug and ring gauges, optical profile projectors, and surface roughness testers to ensure seamless thread engagement and eliminate the risk of galling.
Parts are ultrasonically cleaned, individually sealed or packed in anti-scratch compartments, labeled according to client SKU/barcode specifications, and shipped via express courier or air freight worldwide.
Ti-6Al-4V (Grade 5 / TC4) is the benchmark alpha-beta alloy for structural fastening. By replacing standard carbon steel or stainless bolts with Velnora Grade 5 hardware, racing teams, motorcycle manufacturers, and cycling brands achieve a 44% weight reduction while maintaining tensile strength comparable to Property Class 8.8 and 10.9 steel fasteners.
In addition, titanium forms an instantaneous, regenerative oxide film that provides unmatched resistance to chloride corrosion, road salts, and chemical cleaning agents — completely eliminating rusty bolt heads and seized threads.

Answers to common engineering, tolerance, packaging, and logistics questions.
All Velnora titanium fasteners are machined from certified aerospace-grade Gr5 Ti-6Al-4V or high-purity Gr2 titanium bar stock. Every manufacturing lot undergoes optical dimension sorting, pitch micrometer inspections to DIN, ISO, ANSI, and JIS tolerances, and material traceability testing with EN 10204 3.1 certification upon request.
Yes. Our CNC turning and 5-axis milling workshops handle custom OEM and ODM production based on 2D drawings (PDF, DWG) and 3D CAD files (STEP, IGES). We provide real-time photo and high-definition video updates throughout the machining process so international buyers can approve parts prior to packaging.
We produce clean, micro-polished rolled threads with tightly controlled root radii that substantially reduce friction under preload. For assembly, we recommend applying an anti-seize paste (copper or moly-based) and adhering to torque specifications calibrated for lubricated titanium threads.
We provide natural raw machined, mirror-polished, fine bead-blasted matte, electrochemical anodized (burnt blue, gold, purple, green, rose, rainbow), and super-hard vacuum PVD coatings (DLC deep black, titanium nitride gold, rainbow chameleon) for extreme wear resistance.
Standard catalog fasteners generally require an MOQ of 100 to 300 pieces. Custom CNC engineered parts or Timascus EDC items can be prototyped from smaller test volumes. Standard lead time is 7 to 20 business days depending on quantity, thread pitch requirements, and surface finish.
