Manufactured to ASTM B348, DIN, ISO, and KS B standards. Available in cold-forged and multi-axis CNC machined configurations with heat-lot material verification.
South Korea’s advanced manufacturing sectors—anchored in the high-density industrial corridors of Gyeonggi-do, Ulsan, Changwon, and Incheon—consistently operate under extreme thermal, mechanical, and electro-chemical stressors. Fasteners are frequently the primary point of structural or operational failure when traditional austenitic stainless steels (such as SUS304 or SUS316L) or high-tensile alloy steels are deployed in hostile environments.
As a specialized factory and direct exporter headquartered in Baoji ("China's Titanium Valley") operating since 2013, our production facility delivers Grade 2 (Commercially Pure) and Grade 5 (Ti-6Al-4V) titanium machine screws engineered to resolve chronic industrial bottlenecks: galvanic breakdown, halogen corrosion, mass penalty, and electromagnetic interference.

Our cold-heading machines and multi-axis CNC Swiss lathe centers achieve standard pitch diameters compliant with KS B 0233 and ISO 965-1 thread classes (4h/6g tolerance). All titanium bar raw stock is ultrasonic tested to AMS 4928 standards, guaranteeing zero internal shrinkage, voiding, or micro-cracks before thread rolling.
Our titanium machine screws and custom fasteners are directly integrated into South Korea's flagship manufacturing supply chains, resolving unique technical challenges in each specialized hub.
In wafer fab vacuum chambers, ion-plasma etching, and chemical vapor deposition (CVD) equipment, outgassing and particle flaking ruin production yields. Our titanium DIN 912 and DIN 7991 screws undergo automated multi-stage ultrasonic degreasing to achieve zero hydrocarbon contamination. Their resistance to fluorinated and chlorinated process gases prevents micro-corrosion that generates contaminating metal aerosols.
Korean battery manufacturers require ultra-light fasteners capable of resisting aggressive organic electrolyte solvents and hydrofluoric acid vapors. Titanium machine screws with specialized dielectric PVD insulating coatings prevent thermal galvanic runaway across aluminum-cased cell arrays and cooling plate manifolds, simultaneously lowering vehicle curb weight for higher battery range efficiency.
Busan and Geoje lead global LNG transport and specialized mega-vessel construction. In ballast water management systems (BWMS), seawater cooling channels, and submerged valve fittings, chloride stress-corrosion cracking (SCC) degrades standard stainless bolts within months. Grade 2 pure titanium machine screws form a self-healing rutile TiO₂ oxide layer, delivering a 30+ year maintenance-free lifecycle in deep seawater.
High-speed pick-and-place robotics and surgical robotic arms need minimal payload weight at the wrist joints to avoid servo motor wear and positioning backlash. Replacing stainless hardware with our customized M2–M5 Gr5 countersunk screws reduces inertia by over 40%, boosting motion response times and precision positioning repeatability across high-speed packaging and assembly lines.
Supplying aviation programs centered around Sacheon (KAI) and research facilities in Daedeok, our screws meet strict shear-load thresholds and cyclic thermal fatigue standards from -55°C to 400°C. Tight thread flank engagement eliminates thermal expansion mismatch between carbon-fiber reinforced plastics (CFRP) and structural metal brackets.
Medical imaging devices (MRI, CT scanners) and high-frequency analytical laboratory tools demand zero magnetic interference. Our certified non-ferromagnetic Ti-6Al-4V ELI (Extra Low Interstitial) fasteners allow clean sensor readings without distortion artifacts, while exhibiting full biocompatibility in accordance with ISO 10993 standards.
How South Korean original equipment manufacturers (OEMs) and Tier-1 suppliers are optimizing procurement strategies to meet ESG mandates, KS specifications, and supply chain security.
While DIN and ISO formats are common in global trade, domestic Korean engineering documentation strictly references Korean Industrial Standards (KS). We provide cross-standard manufacturing to ensure pitch tolerances, runouts, and bearing face diameters match both KS B 1002 (Hexagon head bolts) and KS B 0233 (Metric screw thread tolerances), simplifying direct installation across Hyundai, Doosan, and Samsung equipment lines.
Korea's "2050 Carbon Neutrality" initiative has accelerated light-weighting audits across transport and heavy machinery sectors. Replacing conventional fasteners with lightweight Gr5 titanium machine screws directly lowers operational energy demand in moving assemblies, helping domestic exporters comply with EU carbon border adjustments and internal green supplier indices.
Korean purchasing departments are actively mitigating geopolitical vulnerabilities by establishing verified secondary sourcing channels with direct Asian titanium manufacturers. By operating direct freight pathways from Qingdao/Shanghai to Incheon and Busan with sub-7-day ocean shipping times, we ensure resilient buffer inventories for critical infrastructure projects.
Founded in 2013, Yevzo Titanium Metal Co., Ltd. is physically based in the High-Tech Development Zone of Baoji, Shaanxi Province. Baoji processes over 60% of China’s raw titanium sponge and refined mill products. This gives our manufacturing plant direct, immediate access to premium ingot and bar stock with zero intermediary markups.
We combine advanced Japanese cold-heading machines, CNC turning-milling centers, and high-vacuum anodizing equipment to deliver standard catalogue items and bespoke drawing-based fasteners directly to South Korean purchasing agents, distributors, and engineering contractors.
Every fastener is batch-coded back to the original sponge melt ingot with spectrographic chemical analysis and tensile proof records.
