- Thread: UNC / Metric Optional
All items are manufactured from certified virgin Grade 5 (Ti-6Al-4V) and Grade 2 bar stock, providing outstanding strength-to-weight ratios and complete corrosion immunity for Belgrade's rigorous environments.
Belgrade stands as Serbia's technological, logistical, and heavy-manufacturing core. Discover where our Ti-6Al-4V flange fasteners offer measurable structural and commercial advantages.
Facilities across Pančevo and municipal water filtration plants along the Danube face aggressive chloride exposure and sulfuric compound vapors. Unlike plated carbon steel that succumbs to pitting within 24 months, our commercially pure Gr2 and Gr5 flange bolts develop an instant, regenerating titanium dioxide (TiO2) passivation film, avoiding catastrophic joint relaxation in pipeline flanges and chemical reactors.
From custom racing shops around Belgrade Arena to competition karting and motorcycle workshops in Zemun, un-sprung rotational mass reduction is critical. Switching wheel lugs and suspension flange hardware to Gr5 titanium sheds 43%–45% of fastener weight while retaining minimum tensile strength in excess of 895 MPa, radically enhancing damping response times and heat dissipation across heavy braking zones.
With modern developments expanding across New Belgrade (Novi Beograd) and the Belgrade Waterfront, high-load facade assemblies, glazed curtain structures, and overhead light-rail transit canopies demand non-magnetic fasteners resistant to winter de-icing salts. Our precision-formed hex flange bolts distribute clamping stress broadly without requiring separate washers, cutting assembly time by 30%.

A closer look at how changing import paths, green energy mandates, and automotive supply chains in Serbia are driving titanium bolt adoption.
Serbia’s rapid integration into European battery materials and automotive Tier-1 supplier corridors requires lightweighting at every assembly junction. Belgrade contract manufacturers producing e-mobility subassemblies use Grade 5 flange bolts in battery tray housings to eliminate galvanic concerns when pairing with aluminum frames while lowering total vehicular kerb weight.
Procurement teams in the Pančevo-Belgrade industrial belt historically favored electro-galvanized or chrome-moly Class 10.9 steel. However, maintenance audits have proven that shutdown costs, re-torqueing labor, and corrosion failures far surpass the upfront delta of titanium. Specifying DIN 6921 titanium flange bolts ensures a fit-and-forget 25+ year service span.
Belgrade hardware wholesalers previously imported titanium components through multiple European trading intermediaries, causing 45–60 day shipping delays and markups exceeding 70%. By connecting directly with our Baoji manufacturing facilities, Serbian importers get traceable mill certificates, custom laser branding, and wholesale FOB/CIF pricing.
Founded in 2013 in the Honeycomb Industrial Park of Baoji High-Tech Development Zone, Yevzo Titanium Metal Co., Ltd. operates at the epicenter of China’s "Titanium Valley". This unique geographic clustering allows direct, certified access to raw sponge and forged bars (ASTM B348, AMS 4928), preserving clear batch traceability from the ingot melt to finished flange fasteners.
Our machine shop houses over 100 sets of multi-axis CNC lathes, precision thread rolling machinery, and surface treatment setups capable of tight aerospace tolerances (±0.01mm). Guided by our corporate principle—"Titanium concentration, service intention"—our senior engineers assess your thread class, shear margins, and torque expectations before cutting metal.
Practical guidance on customs processing, metallurgy, anti-galling installation, and minimum orders for Serbian enterprises.
