China Top Titanium Disc Screws Manufacturer Serving Košice

Grade 5 titanium (Ti-6Al-4V) delivers an ultimate tensile strength between 895 and 1,000 MPa, making it structurally comparable to property class 8.8 steel bolts while offering a 44% mass reduction and superior fatigue life. For disc rotor systems where the original equipment manufacturer (OEM) specified class 8.8 bolts or standard stainless steel, Gr5 titanium is a superior direct drop-in replacement.

However, if your system utilizes high-tensile class 10.9 (1,000 MPa minimum) or 12.9 (1,200 MPa) bolts subjected to severe clamping shear in industrial heavy machinery, a 1-to-1 dimensional substitution requires an engineering joint verification. In high-demand performance motorcycle and cycling disc brakes, Gr5 titanium provides significant safety margins due to its high fatigue limit and elasticity modulus (approx. 114 GPa), which cushions cyclical impact loads better than rigid carbon steel.

Because titanium has a natural friction coefficient comparable to stainless steel, cold-welding or galling can occur if screws are driven dry under heavy torque into aluminum hub flanges. We strongly advise applying a thin layer of copper-based or nickel-based anti-seize compound, or high-grade synthetic threadlocker (such as medium-strength blue threadlocker, which also acts as an anti-galling barrier during installation).

When using an anti-seize lubricant, remember to decrease the dry nominal tightening torque specification by approximately 15% to 20% to avoid over-tensioning the screw shank. Always use a calibrated torque wrench and avoid using unregulated pneumatic or battery-powered impact drivers during initial thread engagement.

We machine our fasteners using ultra-precise CNC Swiss-type multi-axis lathes from continuous Grade 5 bar stock. Thread execution is carried out via hardened tungsten-carbide rolling dies under flood coolant lubrication rather than basic single-point cutting. This process forms cold-rolled class 6g thread tolerances (tested on standard go/no-go ring gauges to ISO 965 guidelines).

Cold-rolling eliminates micro-burrs and microscopic tear fissures along the thread roots, significantly improving fatigue life under repetitive dynamic cycling.

For standard catalog fasteners (such as M5x10 Torx T25 rotor bolts, M6x20 caliper screws, and stem caps) kept in stock, orders ship within 48 to 72 hours. Custom CNC orders or special anodized batches typically require a production turnaround of 15 to 25 business days depending on batch volume.

For buyers across Košice, shipments are routed via air express (DHL Express, FedEx International Priority, or UPS) directly to Košice (KSC), with transit times typically ranging from 4 to 7 working days. We provide commercial invoices, packing lists with accurate HS tariff codes (typically 8108.90 for titanium articles), and material test certificates to ensure swift customs clearance through Slovak financial authorities.

For standardized production screws, our standard MOQ begins at just 100 to 200 units per sizing profile, allowing specialty bike shops, boutique tuning garages, and engineering workshops across Košice to order small batches cost-effectively.

For custom OEM design development (custom head geometry, countersink angles, specialized thread lengths, or Timascus EDC components), production prototypes can be evaluated starting from 50 pieces, transitioning to full production runs once testing is validated.

Our titanium anodizing process uses no organic chemical dyes. Colorization is achieved purely by electrolytic voltage control, which grows a transparent titanium oxide (TiO₂) layer that acts as an optical interference filter.

Because the color is an integral part of the titanium surface rather than a surface coat of paint, it cannot peel, flake, or blister when exposed to road slush, high humidity, or magnesium chloride de-icing salts. For components in extreme-wear friction contact, we also provide physical vapor deposition (PVD) finishes with micro-hard titanium nitride (TiN) or diamond-like carbon (DLC) coatings.
