In high-performance powersports engineering, motorcycle modification screws represent far more than visual accents—they are mission-critical mechanical components subjected to severe rotational stress, extreme vibration harmonics, and intense thermal cycling. Engineered from vacuum-melted GR5 Ti-6Al-4V titanium alloy, these precision fasteners provide a decisive 44% reduction in unsprung mass compared to carbon steel, while delivering greater tensile strength (>895 MPa) and complete immunity to salt, road brine, and chemical oxidation.
Manufactured by Zunvo Titanium Products Co., Ltd. in Baoji, China's world-renowned "Titanium Valley," our CNC-machined screws, flange bolts, dished head rotors, and spindle axle nuts empower tier-one racing teams, tuning brands, and international distributors across North America, Europe, Central America, the Middle East, and Southeast Asia to engineer superior handling dynamics with uncompromising structural integrity.
Precision-machined from ultrasonically inspected Ti-6Al-4V Grade 5 titanium bars. Head geometries, drive configurations, and thread lengths engineered to OEM and custom race-spec tolerances (ISO 965 / DIN standards).
High-Stress Rated
Engineered for high-torque brake disc mounting (M8x20, M8x24, M10x1.25). Cold-rolled external threads and low-profile flange heads minimize shear fatigue under severe 450°C track braking cycles.
Lightweight Unsprung
Aerospace-profile hex-flange star locking nuts from M14 up to M24. Shaves pivotal rotating weight off front forks and rear swingarms, dramatically sharpening turn-in steering response.
Surface Clamp
Integrated load-distribution washer flanges engineered for clutch covers, water pumps, stator guards, and cylinder blocks. High fatigue endurance stops loosening caused by engine harmonic vibration.
Anti-Camout
Low-profile saucer and pan heads featuring deep hexalobular Torx drives. Ideal for rapid paddock servicing without stripping heads on carbon fiber, composite, or ABS sport fairings.
Cockpit Tuning
Precision CNC-turned pinch bolts (M8x30, M8x40) designed specifically for inverted fork clamps, handlebar controls, and rearset footpeg brackets. Absolute anti-stretch reliability.
Hydraulic Precision
Single and double banjo hydraulic bolts (M10x1.0 and M10x1.25) with cross-drilled fluid galleries. Guarantees leak-proof brake and clutch fluid transfer resistant to DOT 4/5.1 corrosive fluids.
Strategic analysis for brand procurement officers, aftermarket racing suppliers, and wholesale importers planning future product lines.
The global motorcycle modification screws industry is undergoing a structural transition driven by the explosive growth of high-displacement street naked bikes, track-focused superbikes, and premium adventure-touring machines. Sourcing managers are adapting to three primary shifts:
At Zunvo Titanium Products Co., Ltd., we maintain extensive raw titanium stocks and automated multi-axis Swiss CNC cells to fulfill contract manufacturing runs within 7 to 15 days, minimizing warehouse capital lockup for international partners.
Historically, motorcycle screws relied on standard zinc-plated 8.8 grade carbon steel or 304/316 stainless steel. However, performance and aesthetic expectations have propelled titanium to the industry benchmark:
| Raw Material | Certified Ti-6Al-4V Grade 5 (Alpha-Beta Titanium) |
|---|---|
| Tensile Strength | 950 – 1050 MPa (Surpasses Class 8.8 Steel) |
| Yield Strength | ≥828 MPa (0.2% Offset proof stress) |
| Machining Precision | CNC Turning / Milling up to ±0.005 mm tolerance |
| Surface Treatment | Anodizing (Voltage Controlled) & PVD Titanium Nitride |
| Drive Profiles | Torx (T20, T25, T30, T40, T50), Hex Socket, Drilled Flange |
A precision manufacturing workflow designed for global motorcycle brands, private label aftermarket suppliers, and custom racing fabricators.
Evaluation of 2D/3D CAD models (STEP, DWG, IGES). FEA stress analysis and titanium grade optimization for brake or chassis loads.
Rapid CNC setup producing physical samples in 72 hours for geometric alignment, fitment testing, and torque checking.
Ultrasonic degreasing followed by anodization or PVD coating. Exact batch color spectrum matching against client benchmarks.
Mass production across our multi-spindle Swiss CNC turning centers and thread rollers to ensure strict concentricity.
Coordinate Measuring Machine verification, optical sorting, laser logo etching, and custom retail packaging dispatch.
Zunvo Titanium Products Co., Ltd. is a specialized enterprise founded in Baoji, China, operating for over ten years in the research, engineering, and manufacturing of premium titanium alloy screws, motorcycle modification screws, nuts, bolts, titanium washers, titanium shaped parts, and titanium bicycle screws.
Positioned at the epicenter of China's primary titanium smelting and processing hub ("Titanium Valley"), we maintain direct upstream raw bar contracts. This guarantees 100% pure vacuum-arc remelted Ti-6Al-4V bar stock with comprehensive mill certificates, eliminating non-conforming or contaminated imports.
Comprehensive answers compiled from international B2B inquiries across North America, Europe, Australia, and Asia. Have specific technical requirements? Our engineering team responds in ≤7 hours.
Grade 5 (Ti-6Al-4V) is an alpha-beta titanium alloy heat-treatable to tensile strengths exceeding 895–1050 MPa and yield strengths above 828 MPa. This makes it structurally capable of replacing property class 8.8 and 10.9 steel fasteners in high-load areas such as brake discs, suspension linkages, and triple tree clamps. Grade 2 is commercially pure titanium with a tensile strength of roughly 345–400 MPa; using Grade 2 in structural or dynamic chassis positions poses severe failure risks under braking or cornering loads. Zunvo exclusively manufactures load-bearing motorcycle modification screws from certified GR5.
For standard Class 8.8 positions (fairings, subframes, engine cases, handlebar switchgear, foot controls), GR5 titanium is a direct 1:1 replacement offering identical or superior strength with 44% weight reduction. For positions specified by factory manuals as Class 10.9 (brake caliper mounts, swingarm pivots), GR5 titanium is frequently utilized when properly torqued. For ultra-high tensile 12.9 applications (cylinder head studs), Zunvo engineers analyze the joint geometry to determine whether upsizing the thread pitch or maintaining specialized alloy steel is necessary to uphold safety factors.
Thread galling occurs when friction strips microscopic oxide layers between sliding metal contacts. Galvanic corrosion can occur due to potential differences between titanium and aluminum in electrolytic environments. We advise: (1) Applying an anti-seize paste containing copper, nickel, or molybdenum disulfide (MoS2) onto the titanium threads prior to assembly; (2) Utilizing precision CNC-rolled threads, which are dramatically smoother than cut threads; (3) Tightening fasteners using calibrated torque wrenches to OEM wet-torque values (typically 10-15% lower than dry torque).
No. Titanium anodization does not rely on organic dyes or pigments. Colors (gold, blue, purple, bronze, rainbow) are produced via thin-film light interference from a transparent titanium dioxide (TiO2) layer grown electrochemically on the surface. Because there is no dye molecule, UV radiation cannot bleach the color. For components subjected to frequent abrasive contact (such as footpeg bolts or wheel lug nuts), we also offer Physical Vapor Deposition (PVD) coatings (DLC Black and TiN Gold), which offer surface hardness exceeding 2500 HV.
For standard motorcycle modification screws in stock (natural finish and standard anodized colors), our MOQ starts as low as 100 dozens or 100 pieces per size, dispatching within 24–48 hours. For bespoke custom designs requiring tooling setup or custom CNC programming, sample batches ship in 3 to 5 business days, while volume production runs (5,000–50,000 pcs) typically ship within 7 to 15 days following first-article signoff.
We routinely export to North America, Central America, the Middle East, Southeast Asia, and Europe. Expedited samples ship via DHL, FedEx, and UPS (3–5 day delivery). Commercial freight moves via bonded air cargo or consolidated ocean shipping (FOB, CIF, DDP). We accept standard international commercial payment methods including Wire Transfer (T/T), L/C, and PayPal in USD.
