Engineered Fastening Solutions: Recommended Product Line
Certified Ti-6Al-4V Grade 5 (TC4) precision socket bolts, racing-spec hardware, and ultra-durable accessories developed for heavy-load, high-vibration powertrain and structural assemblies across Kawasaki's industrial applications.
Direct Supply for the Kawasaki Coastal & Inland Industrial Belts
Whether you require standard metric hex socket screws (DIN 912 / JIS B1176) for precision machinery or ultra-lightweight race-spec bolts for high-displacement motorcycle builds (Ninja ZX-10R, ZX-6R, Z900RS platforms), our manufacturing line provides rolled-thread integrity, aerospace grade tolerance control (ISO 4h/6g), and batch-level spectral verification.
Engineering Demands: Titanium Socket Screws in Kawasaki's Ecosystem
From the Keihin Industrial Zone's petrochemistry and port logistics to motorcycle tuning centers in Kanagawa, Grade 5 Ti-6Al-4V fasteners resolve fundamental mechanical failure modes caused by marine salinity, cyclic thermal shock, and critical rotational inertia.
Unsprung Mass Reduction in Motorsports
In high-torque superbike platforms engineered and tuned throughout Kawasaki and surrounding circuits, unsprung rotating mass directly governs gyroscopic resistance and suspension compliance. Replacing OEM steel caliper bolts, brake disc rotor pins, and sprocket fasteners with Velnora Ti-6Al-4V hardware achieves a 44% mass reduction while delivering an ultimate tensile yield above 895 MPa.
Resistance to Coastal Saline Corrosion
Operating throughout Tokyo Bay and the Kawasaki port facility exposes assembly hardware to aggressive chloride-rich atmospheric mist. Unlike 304 and 316 stainless steels, which remain vulnerable to localized pitting, stress-corrosion cracking (SCC), and crevice oxidation under marine humidity, titanium immediately forms an unyielding TiO2 passivation layer with infinite corrosion life.
Cyclic Fatigue and High Thermal Stability
Engine mounts, exhaust manifold junctions, and radial master cylinder mounts experience rapid thermal cycling from ambient humidity to exhaust gas temperatures exceeding 400°C. Grade 5 titanium retains mechanical shear resilience and high modulus elasticity across extreme temperature fluctuations without embrittlement or micro-fracture propagation.

Manufacturing Excellence: Why Kawasaki Engineers Trust Velnora
Operating from Baoji, China's designated "Titanium Valley," Velnora Titanium Industry Co., Ltd. combines raw material sovereignty with multi-axis precision Swiss-lathe turning, centerless grinding, and cold-thread rolling to deliver industrial-grade hardware across the Japanese archipelago.
Continuous Grain Flow Thread Rolling
Unlike budget suppliers who machine screw threads on standard lathes—shearing through metal grains and generating stress-concentration micro-notches—our socket screws feature fully cold-rolled threads. This preserves the internal crystalline grain flow of the Ti-6Al-4V bar, dramatically elevating shear resistance, fatigue endurance, and cycle life under peak torque.
Traceable Raw Material Certification
Every billet of Ti-6Al-4V Grade 5, CP Grade 2, and specialized Timascus (Mokuti) is sourced from certified aerospace sponge melt houses. We supply comprehensive EN 10204 3.1 Material Test Reports (MTR), detailing exact chemical constituents (C, Fe, N, H, O, Al, V) and mechanical pull tests, ensuring your compliance with strict Japanese industrial procurement audits.
Advanced PVD & Anodic Surface Hardening
Titanium can exhibit susceptibility to galling and adhesive friction when threaded into matching female materials without lubrication. We offer specialized physical vapor deposition (PVD) titanium nitride (TiN), DLC (Diamond-Like Carbon), and micro-arc high-voltage anodizing (burnt blue, gold, purple) to minimize friction coefficients and maximize wear resilience.

Clear, uncompromised technical guidelines addressing torque ratios, anti-galling preparations, standards compliance, and direct factory import procedures into the Kawasaki metropolitan area.
Can Velnora Grade 5 titanium socket screws directly replace JIS / DIN 10.9 or 12.9 high-tensile steel bolts? +
Grade 5 (Ti-6Al-4V) titanium delivers a minimum ultimate tensile strength of approximately 895 to 1,000 MPa, making it directly comparable to Property Class 8.8 and near Class 10.9 carbon steel. However, titanium possesses an elastic modulus of approximately 114 GPa—roughly half that of steel (205 GPa). For non-safety critical, unsprung mass reductions (calipers, covers, brackets, bodywork), titanium is a direct high-performance upgrade. For critical powertrain shear pins or cylinder heads rated strictly for 12.9 high-tensile alloys, structural joint analysis or an increase in thread nominal diameter (e.g., M8 to M10) is advised.
What torque values and anti-seize protocols should be applied during installation? +
Due to titanium's low friction under micro-movement and its tendency toward galling (cold-welding) when mating with dry titanium or aluminum housings, never assemble dry. We strongly advise applying an anti-seize compound containing molybdenum disulfide (MoS2), copper, or nickel paste. When using lubrication, nominal torque figures should be reduced by 15% to 20% compared to standard dry-steel JIS specifications to avoid over-stretching the shank while securing the required clamp load.
Are your socket cap screws manufactured to JIS B1176 or DIN 912 standards? +
We manufacture to both standards upon request. While DIN 912 and JIS B1176 share identical thread pitches across standard metric increments (e.g., M6x1.0, M8x1.25), slight dimensional head variances exist in socket broaching depth and head diameter tolerances. We verify your exact drawing or designated standard before launching CNC multi-spindle runs. Custom tapered, low-profile, button, or wire-drilled race heads are fully supported.
What is the typical transit schedule and logistics pipeline from Baoji to Kawasaki / Yokohama? +
For sampling and batch production volumes up to 500 kg, air express door-to-door transit (via DHL, FedEx, or SF International) typically delivers directly to Kawasaki, Yokohama, or Tokyo within 3 to 5 business days after customs clearance. Bulk container ocean shipments route directly via Qingdao/Tianjin ports into Tokyo Bay (Kawasaki Port) with a maritime shipping duration of only 4 to 6 days, offering fast regional turnaround.
What are the minimum order quantities (MOQ) for custom-dimensioned CNC parts? +
For standard DIN/JIS titanium socket screws in inventory, our MOQ begins at 50 to 100 pieces per spec. For full custom OEM/ODM designs submitted via CAD files (STEP, IGES, or 2D PDF), our typical production batch MOQ is 100 to 300 pieces. Exotic Damascus titanium (Timascus / Mokuti) customized parts, such as precision EDC keycaps, pens, or decorative plates, can be manufactured from 1 piece upward.
