Engineered to DIN 912, ISO 4018, and bespoke OEM flight/automotive specifications. Each cold-forged and CNC-turned fastener delivers superior strength-to-weight ratios and verified corrosion fatigue limits.
A comprehensive engineering evaluation of mechanical stress limits, cyclic fatigue thresholds, and non-galling fastener design for advanced procurement.
Grade 5 (Ti-6Al-4V) titanium delivers a nominal tensile strength exceeding 895–1000 MPa while maintaining a low density of 4.43 g/cm³. This enables a 44% direct weight reduction compared with ISO Class 8.8 and 10.9 alloy steel socket screws, eliminating unnecessary rotational inertia and un-sprung chassis mass in high-performance assemblies.
Unlike standard stainless steels (A2-70, A4-80), titanium exhibits an authentic fatigue endurance limit under high-frequency alternating shear stress. In motor racing calipers, powertrain fixtures, and aerospace nacelles, our DIN 912 titanium socket cap screws withstand extensive vibration harmonics without micro-fissuring at the thread root or under-head radius transition.
Titanium instantly generates a robust, chemically stable TiO2 ceramic film when exposed to ambient oxygen. This self-healing boundary provides total immunity to chloride stress corrosion cracking, acidic industrial washdowns, brake fluids, and galvanic marine exposure that would rapidly destroy zinc-plated and galvanized fasteners.

How global electrification, hydrogen infrastructure, and lightweight robotics are redefining fastener specifications over the next decade.
Automotive OEMs are transitioning from heavy steel studs to M12/M14 titanium hub, battery-pack, and motor-mount socket bolts. Reducing every kilogram of chassis weight directly increases EV range and decreases tire wear, making titanium's price-to-weight ratio more commercially viable for large-scale electric platforms.
Additive manufacturing in aerospace and medical devices creates complex topologies that require high-precision internal thread engagement. Designers are increasingly demanding custom socket screws with bespoke head counterbores, micro-drilled safety wire holes, and modified pitch diameters that prevent thread loosening under extreme thermal cycling.
Historically, titanium threads were prone to galling during dry assembly. The current trend focuses on factory-applied functional finishes, including MoS2 dry-film lubricants, diamond-like carbon (DLC), and optimized micro-arc oxidation, eliminating the reliance on manual copper-based anti-seize pastes in cleanroom environments.
Global supply chain risk management requires validated traceability from titanium sponge smelting to final socket head broaching. Modern procurement directors require EN 10204 3.1 chemical and mechanical inspection certificates alongside non-destructive ultrasonic and eddy-current batch validation.
Operating since 2013, Yevzo Titanium combines an integrated non-ferrous supply chain with multi-axis precision machining to provide complete OEM/ODM production.
Located in the Honeycomb Industrial Park of Baoji, Shaanxi, we source ASTM B348-compliant titanium bars directly from local mill consolidators. This geographic advantage insulates buyers from broker markups and gives us direct oversight of metallurgical purity.
Our workshop houses over 100 sets of precision CNC turning machines, automatic thread rolling stations, and optical sorting machines. Rather than cutting threads—which severs grain structure—our socket screws feature cold-rolled threads that enhance root fatigue strength by up to 30%.
Every lot undergoes 100% thread gauge verification (6g/6H tolerances), spectrometer alloy composition testing, hardness checks (HRC 30-36 for Gr5), and optical surface flaw scanning before final ultrasonic degreasing and packaging.
We serve industrial partners across North America, Northern Europe, and the Asia-Pacific region under Incoterms including FOB, CIF, DDP, and door-to-door express delivery, backed by multiple currency clearing (USD, EUR, GBP, JPY).
Essential technical and logistical answers to support industrial procurement, engineering selection, and quality management.
