Positioned at the epicentre of global aircraft leasing and transatlantic base maintenance, Limerick’s aviation ecosystem demands unprecedented agility in precision Grade 5 titanium hardware supply.
Shannon-based Part-145 stations conducting C & D structural checks on narrowbody (A320/B737) and widebody aircraft cannot afford Aircraft-on-Ground (AOG) bottlenecks caused by standard European distribution stockouts. Our direct Jiaxing manufacturing lines provide express priority shipments for specialized fasteners.
Over 50% of the world's leased commercial aircraft fleet is managed through Ireland, with Limerick and Shannon housing leading asset managers. Mid-lease transitions and cargo conversions require non-structural modifications and secondary titanium hardware replacements that meet stringent FAA/EASA documentation thresholds.
County Limerick and Clare boast exceptional high-precision subcontractors machining turbine casing parts and wing ribs. We act as an upstream Tier-1 raw material and semi-finished titanium bolt exporter, providing precision unthreaded blanks, rolled threads, and custom hot-forged preforms to local machine shops.
From jet engine overhaul facilities on the Shannon Estuary to composite manufacturing labs in Castletroy and Raheen, our titanium solutions operate where corrosion, vibration, and thermal expansion failure are unacceptable.
In CFM56, LEAP-1A/1B, and V2500 engine teardowns and nacelle repairs performed near Shannon Airport, standard fasteners fail due to cyclic thermal fatigue up to 350°C. Our Ti-6Al-4V Grade 5 hex and socket cap bolts maintain optimal pre-load torque without yielding or seizing, reducing galvanic corrosion risks when contacting carbon-fibre composite fairings.
The rear fuselage and APU bay suffer extreme vibration harmonics. Our hot-forged titanium self-locking flanged nuts with prevailing torque deformation collar systems prevent hardware back-off without requiring messy safety wiring or chemical threadlockers during quick line replacements.
With regional freight hubs expanding at Shannon Airport, passenger jetliners are undergoing rapid conversion to freighters. This involves heavy installation of main cargo door surrounds, barrier nets, and heavy-duty floor roller tracks. Our lightweight high-shear countersunk UNF screws maximize payload capacity by shedding hundreds of kilograms over legacy steel fittings.
Exposure to runway de-icing salts, marine coastal moisture from the Shannon River estuary, and brake disc temperatures exceeding 400°C causes severe pitting on cadmium-plated steel bolts. Titanium rotor disc studs and caliper fasteners provide complete chemical immunity, eliminating stress corrosion cracking (SCC).
Line engineers and maintenance technicians across Limerick’s aviation maintenance parks utilize our non-magnetic, spark-free Grade 5 titanium tooling and custom pins for avionics calibration bays and high-risk fuel vapor maintenance environments.
Procurement teams and stress engineers in Shannon's aviation cluster require unambiguous data when approving technical deviations and material substitutions.

Navigating the next decade of fleet modernization, sustainable aviation fuel (SAF) transition, and regional precision manufacturing in Ireland.
With Irish aviation committed to European Fit for 55 targets, every gram shaved off operating empty weight (OEW) saves tons of jet fuel over an airframe’s operational lifespan. Limerick maintenance operations are systematically upgrading cabin secondary structures, seat track fixings, and galleys to Gr5 titanium fasteners, offsetting battery and SAF conversion weights.
Global aerospace supply chains face persistent lead times exceeding 52 weeks from historical suppliers in the US and Western Europe. Limerick procurement departments have diversified toward Jiaxing Wexra, benefiting from China’s massive upstream sponge titanium refining scale, rapid billet availability, and nimble batch turnaround times.
Irish revenue and Shannon Foynes clearance procedures require crystal-clear HS code declarations (7508.90, 8108.90) and full REACH/RoHS toxicological compliance. We provide digitized material tracing dossiers, complete with optical emission spectroscopy (OES) chemical analysis and dimensional optical scan files before goods leave China.
Founded in 2018 in Jiaxing, Zhejiang—the manufacturing heartland adjacent to Shanghai—Jiaxing Wexra Titanium Products Co., Ltd. is a dedicated manufacturer and exporter specialized strictly in titanium and titanium alloy hardware. We maintain end-to-end sovereignty across every step of component execution, eliminating third-party markups and quality variances.
No fastener leaves our factory without satisfying strict internal metallurgical and dimensional gates:
Clear, expert answers addressing material release certifications, Shannon freight logistics, tariff codes, and anti-galling installation best practices.
Every production batch supplied to the Irish market comes accompanied by an authentic EN 10204 Type 3.1 Inspection Certificate validating the exact chemical composition (Spectrographic analysis) and mechanical properties (Yield, Tensile, Elongation, Hardness) against aerospace specifications such as AMS 4928 and ASTM B348. For non-OEM Standard Part (NAS / MS / AN style) applications or custom-engineered bracketry, our full traceability dossiers ensure full compliance during Part-M airworthiness reviews and lessor transition audits.
For urgent AOG and rapid MRO replenishment, express air freight options (DHL / FedEx Express / Air Cargo via Shanghai PVG to Shannon SNN or Dublin DUB) deliver within 4 to 6 business days. For scheduled replenishment and stock orders, sea-air multimodal or direct ocean freight via Shanghai Port to Shannon Foynes Port or Dublin Port operates on predictable 28 to 35-day turnaround schedules, with full customs clearance pre-advising.
Titanium has a high coefficient of friction that can lead to cold welding (galling) under high torque tightening. We mitigate this through two distinct engineering techniques: First, we supply specialized surface treatments including aerospace-grade micro-arc oxidation, titanium anodizing (AMS 2488 Type II), and PVD anti-friction coatings. Second, we provide exact engineering guidelines for approved aerospace anti-seize pastes (such as molybdenum disulfide or cetyl alcohol lubricants), ensuring torque tension ratios match calculated pre-loads without seizing.
Yes. Our in-house engineering team works directly with STEP, IGES, SolidWorks, and 2D CAD blueprint files under Non-Disclosure Agreements (NDAs). We perform Design for Manufacturability (DFM) reviews to identify opportunities to reduce cycle times and optimize material utilization. Prototyping quantities (from 5 to 50 pieces) can be machined within 7 to 10 working days, followed by scalable production runs of thousands of pieces with batch-to-batch repeatability.
Civil aircraft components and standard fasteners categorized under TARIC codes 8108.90 and 7318/8108 typically benefit from duty suspension or standard WTO rates into Ireland when certified for civil aviation usage. Because our fasteners and CNC parts are built to standardized civil aerospace and industrial specifications, standard commercial invoices, packing lists, MTCs, and Certificates of Origin ensure swift Irish Revenue (Customs) clearance through the automated AIS system without unnecessary dual-use export delays.
To accommodate prototype engineering, testing, and MRO overhaul batches, standard catalog fastener items feature low MOQs starting from 100 to 500 units. For fully bespoke CNC machined aircraft brackets and fittings, we support initial sample lots from 10 units. We offer standard international payment terms (T/T, LC) and flexible corporate billing terms for established Irish procurement partners following credit assessment.
Whether you require express replenishment for Shannon MRO lines, bespoke CNC brackets for Limerick precision machining projects, or long-term contract pricing on aerospace Gr5 fasteners, our engineering team is ready to review your CAD files and bill of materials.
