Directly forged and five-axis CNC machined at our Baoji facility, our product catalog meets the highest DIN, ISO, and race-spec motorsport standards required across Thessaloniki, Central Macedonia, and export trade corridors.
In demanding engine configurations, transmission cases, and marine sumps operating along the Aegean coastline, stock aluminum alloy and carbon steel oil drain bolts present inherent failure points. As China's leading dedicated titanium bolt manufacturer, we integrate grade Ti-6Al-4V bar stock with high-temperature permanent magnetic inserts to eliminate galling, stripped pan threads, and ferrous circulation.
Constructed exclusively from certified Ti-6Al-4V (Grade 5), delivering a yield strength exceeding 828 MPa. Unlike soft 6061-T6 aluminum plugs that deform under repetitive maintenance torquing, GR5 matches 10.9-grade tensile resistance while remaining 43% lighter than steel, preventing thread shear in cast magnesium and aluminum pans.
Our drain bolts integrate hermetically bonded N45SH or N52H neodymium rare-earth magnets capable of enduring operating temperatures up to 150°C (302°F) without magnetic demagnetization. Delivering over 5,000 Gauss at the tip, micro-ferrous shavings down to 5 microns are trapped before entering delicate oil channels.
Engineered specifically for motorsport competition, maritime outboards, and severe vibration environments. The hex head features multi-axis pre-drilled safety-wire cross-holes (1.8mm - 2.0mm), complying strictly with FIM, FIA, and offshore Coast Guard race scrutineering guidelines to guarantee zero back-out failure.

Thessaloniki serves as the primary maritime, commercial, and automotive logistical nexus for Northern Greece and the Balkans. Operating conditions here demand specialized mechanical components that resist both marine coastal corrosion and intense thermal dynamics.
The Port of Thessaloniki (ThPA) and coastal fishing operations experience aggressive marine salt air. Stock steel sump plugs on inboard/outboard diesel engines corrode rapidly. Our GR5 titanium plugs maintain absolute structural passivity, preventing salt-induced seizing during seasonal offshore servicing.
Located just an hour from Thessaloniki, the Serres Racing Circuit hosts international superbike and touring car championships. Thessaloniki’s tuning houses install our safety-wired titanium magnetic plugs to ensure race-critical containment of transmission and dry-sump metallic particulates.
Logistics operators traversing the trans-Balkan Egnatia highway subject commercial turbo-diesel engines to continuous high-load ascents. Our magnetic titanium plugs allow fleet technicians to quickly inspect driveline wear during rapid turnarounds, averting catastrophic bearing failures.
Rental speedboats, jet skis, and luxury yachts stationed around Halkidiki undergo continuous cycling under extreme humidity and brackish water. Replacing OEM steel plugs with our Ti-6Al-4V magnetic units protects expensive cast-aluminum marine lower units from irreversible thread damage.
The Greek manufacturing and automotive aftermarket is undergoing a generational shift toward precision components, driven by decarbonization, predictive maintenance, and strategic location advantages.
Fleet managers in Sindos Industrial Park are implementing visual debris inspections during scheduled oil changes. High-gauss magnetic drain plugs serve as mechanical sensors, catching early gear flaking before particles trigger costly engine tear-downs.
Importers based in Kalochori are leveraging Thessaloniki’s rail and highway connections to distribute high-margin performance hardware into North Macedonia, Bulgaria, and Albania. Premium titanium fasteners provide high value-to-weight ratios for regional logistics.
As electrified vehicles enter the Northern Greek market, independent workshops in Kalamaria and Toumba are servicing compact, high-RPM electric reduction gearboxes. These gearboxes rely on neodymium magnetic plugs to safeguard precision reduction planetary gears from micro-spalling.
Based in Baoji, China’s renowned "Titanium Valley," Verqo Titanium Products Co., Ltd. controls the entire production chain from certified raw sponge melting and bar extrusion to CNC five-axis machining and automated surface treatment.
Operating within China's primary titanium industrial cluster, we source virgin aerospace sponge. Every production lot is delivered with EN 10204 3.1 inspection certificates, spectroscopic chemical assays, and mechanical tensile validation.
Our CNC turning equipment rolls threads to class 6g tolerances rather than cutting them, ensuring unbroken grain flow and fatigue resistance. Standard metric pitches (M12×1.25, M12×1.5, M14×1.5, M16×1.5, M20×1.5, M26) and custom threads are produced on demand.
We provide micro-arc oxidation and physical vapor deposition (PVD) finishes in Burnt Blue, Oil-Slick Rainbow, Titanium Gold, Deep Purple, and Hard Diamond-Like Carbon (DLC) Black, combining aesthetic quality with high surface lubricity.
We maintain an industry-leading 98.62% verified inquiry response rate. Our engineering desk provides technical drawing verification, quote breakdowns, and production lead times within two hours during regular European trading windows.
Whether you require a pilot batch of 20 pieces for dyno prototyping or contract orders of 10,000 units for distributor packaging, our factory accommodates custom laser etching, customized branding, and direct air express routing into Thessaloniki Airport (SKG).
We assist European brands with custom head logo engraving, specific wrench hex drive formats (internal Torx, external hex, or low-profile flanged sockets), and pre-packaged blister packs featuring Hellenic and English technical labeling.
Critical technical and transactional inquiries addressed directly by our senior production engineers.
Because GR5 titanium has a tensile strength of ~895 MPa (exceeding standard factory bolts), it easily tolerates manufacturer torque specs. However, because most sumps are cast aluminum or stamped steel, we recommend torquing to OEM engine specs (typically 25–35 Nm for M14 bolts) and applying a smear of anti-seize lubricant to prevent thread galling.
Our manufacturing line uses an interference press-fit combined with a 360-degree precision rolled mechanical lip and high-temperature anaerobic aerospace retaining compound rated up to 180°C. The magnet cannot dislodge or loosen into the oil pan under severe engine harmonics.
Shipments sent via express air courier (DHL, FedEx, UPS) typically arrive in Thessaloniki (SKG) within 4 to 7 business days from dispatch. We provide commercial invoices, packing lists with correct HS codes (7318.15 / 8108.90), and origin declarations for smooth import clearance through Greek customs authorities.
Yes. We regularly produce specialized metric pitches such as M12×1.25, M14×1.25, M16×1.5, M18×1.5, M20×1.5, M24×1.5, and M26×1.5, as well as British Standard Pipe (BSP) and NPT threads for marine and commercial sump housings, based on your technical drawing or physical sample.
We recommend annealed copper washers or fluorocarbon (Viton) O-ring seals for titanium sumps. Soft aluminum crush washers are also acceptable. Our titanium flange faces are precision-ground flat to a surface roughness of Ra 0.4 to prevent oil weepage even without liquid sealant.
We accept wire transfer (T/T), Letter of Credit (L/C), and PayPal for sample orders. For regular volume distributors in Thessaloniki, we support flexible arrangements such as 30% deposit with the 70% balance payable upon presentation of the Bill of Lading (B/L) and full QA inspection reports.
