Precision Aerospace & Mobility Grade Titanium Fasteners
Custom CNC turned, cold-forged, and rolled-thread Torx bolts built specifically to endure extreme mechanical shearing, cyclic resonance, and thermal oxidation.
Structural Mechanics: The Superiority of Internal Torx (Hexalobular) Geometry in Titanium Alloys
In dynamic mechanical assemblies subjected to sustained shear and harmonic vibrations, fastener drive geometry plays a decisive role in clamping reliability. While legacy drive profiles such as internal hex (Allen) and standard cross-recess depend on surface friction across angular vertices, ISO 10664 hexalobular internal Torx drives introduce radial curve contact. This geometry reduces the cam-out drive angle to virtually zero degrees, preventing stress concentrations at bolt drive margins.
When working with Ti-6Al-4V Grade 5 (ASTM B348 / AMS 4928), drive geometry becomes even more critical. Titanium has a lower modulus of elasticity (approximately 114 GPa compared to 210 GPa in high-tensile structural steel). Under high initial assembly torques, conventional socket head cap screws often experience notch rounding or tool reaming. Wexra's cold-formed Torx drive sockets maintain strict dimensional parity with precision CNC tooling, ensuring radial torque transfer occurs without head splay or localized plastic deformation.

Furthermore, our manufacturing process incorporates dedicated thread-rolling technologies rather than single-point thread cutting. Thread rolling forces the titanium alpha-beta grains to flow uninterrupted along the crests and roots of each thread flank, boosting fatigue cycle thresholds by more than 30% against dynamic reversing stresses.

Regional Industrial Convergence
Tailored Fastener Deployments across the Lyon & Rhône-Alpes Metropole
From the high-tech corridors of Gerland to the precision engineering workshops of the Vallée de l'Arve and Saint-Étienne, our fasteners provide critical holding power.
Valley of Arve & Subcontracting Hubs
The Auvergne-Rhône-Alpes region is Europe's center for bar turning (décolletage) and sub-assembly contracting. Our Grade 5 Torx fasteners provide machine builders with drop-in, zero-defect hardware that meets rigid French national defense and civil industrial tolerances.
Chemical Corridor & Process Skids
Lyon's historic Couloir de la Chimie chemical valley demands fasteners that resist aggressive chlorides and corrosive media. Our Grade 2 and anodized Grade 5 Torx fasteners form an instant, passive TiO2 oxide barrier that stops galvanic rust in industrial processing machinery.
Mobility & High-Performance Cycling
Rhône-Alpes sits at the center of European mountain biking, endurance sports, and motorsport engineering. We supply high-modulus disc rotor bolts, flanged crank fasteners, and lightweight chassis studs that cut unsprung rotating mass while resisting road salt and moisture.
Sourcing Trends: Carbon Neutrality, REACH Directives & Dual-Sourcing Resilience
Manufacturing companies across Lyon, Villeurbanne, and the surrounding Auvergne-Rhône-Alpes basin are adapting to stricter corporate sustainability goals and tighter European supply chain regulations. The drive to replace heavy alloy steels with lightweight Ti-6Al-4V fasteners is directly linked to industrial decarbonization. In transport and dynamic machinery, cutting fastener mass by 44% lowers overall inertia, reducing power draw across long duty cycles.
Purchasing managers increasingly require full regulatory compliance. Every batch of Wexra titanium fasteners ships to France fully compliant with EU REACH (EC 1907/2006) and RoHS (2011/65/EU) mandates. Our chemical pickling and anodization lines operate in closed loops, eliminating heavy hazardous chemistry and ensuring components are ready for clean industrial environments.
At the same time, regional Tier-1 and Tier-2 manufacturers are moving away from fragile, single-region supply lines. Our direct factory delivery model provides continuous OEM production with consistent batch testing. Every order includes complete EN 10204 3.1 inspection documentation, giving engineering teams direct factory access without the cost markups of European retail re-sellers.

Equipped with ultra-rigid Swiss-type automatic lathes and 5-axis CNC centers, our lines achieve tight dimensional tolerances down to ±0.01 mm. This allows us to hold exact Torx drive depths, precision thread concentricity, and burr-free chamfers at volume scale.
Certified Quality Systems
Operating under certified ISO 9001:2015 standards, every production lot is checked with optical comparators, automated thread go/no-go gauges, and micro-hardness testers. We maintain full traceability from incoming raw bar to final export packaging.
Procurement Guidance
Technical FAQ for Industrial Sourcing in France
Clear, direct engineering answers to help buyers, structural analysts, and procurement teams source titanium fasteners with confidence.
How do Grade 5 (Ti-6Al-4V) Torx bolts compare to standard 8.8 and 10.9 structural steel?
Ti-6Al-4V Grade 5 titanium offers an ultimate tensile strength of 895 to 1000 MPa, putting it on par with Grade 10.9 high-tensile alloy steel (~1040 MPa) and far ahead of standard Class 8.8 steel (~800 MPa). However, at 4.43 g/cm³, titanium is roughly 44% lighter than steel (7.85 g/cm³). Grade 5 also delivers exceptional fatigue endurance and corrosion resistance without the need for sacrificial zinc plating or maintenance coatings.
What torque values and lubricants should our assembly teams use to prevent thread galling?
Titanium forms a thin, tough titanium oxide film that can cause galling under dry, high-friction assembly. We recommend applying an anti-seize paste—such as a nickel-based, MoS2, or copper anti-seize paste—before assembly. Because anti-seize lowers friction coefficients, tightening torque values should generally be reduced by 15% to 20% compared to dry steel fasteners. We provide specific torque-tension charts based on your application and target clamping loads.
Do you supply EN 10204 Type 3.1 Mill Test Certificates with incoming orders in France?
Yes. Every shipment includes certified EN 10204 Type 3.1 inspection documentation. Our reports record actual chemical heats (Al, V, Fe, C, N, H, O) along with measured mechanical test figures: yield strength (Rp0.2), tensile strength (Rm), elongation percentage (A%), and reduction of area (Z%). This makes our documentation easy to integrate into your existing quality and supplier verification systems.
Can you manufacture non-standard custom stepped or shoulder Torx bolts from client drawings?
Yes. Our custom engineering services handle non-standard head diameters, unique shoulder lengths, captive washer assemblies, deep-socket Torx Plus drives, and specific thread pitches. Send your technical drawings via live chat or CAD export (STEP, IGES, or PDF) for a prompt manufacturability review and quote within 8 business hours.
How do you handle shipping logistics, French customs clearance, and import duties?
We ship regularly to France and across the EU using DAP (Delivered at Place) or DDP (Delivered Duty Paid) via air express (DHL, FedEx, UPS) for quick turnaround, as well as consolidated air and sea freight for larger production orders. All international packaging uses barcode labels, full commercial invoices, and proper HS code classifications (typically 8108.90 for finished titanium components) to ensure smooth EU customs clearance.
