ISO7380 m5x10mm Titanium Bolts — Lightweight, High-Strength Fastening Solutions for Demanding Applications

ISO7380 m5x10mm titanium bolts are precision fasteners manufactured to the ISO 7380 hexagon socket button head standard, featuring an M5 × 0.8mm thread pitch and 10mm thread length. Weighing only 0.6-0.7g apiece, these aerospace-grade Ti-6Al-4V (Grade 5) bolts are roughly 45% lighter than steel counterparts, and provide tensile strength of 895-1,000 MPa. The low-profile button head design offers a clean, aerodynamic finish for weight-sensitive and appearance-critical assemblies. Burned blue or polished finishes are available, and we offer complete OEM/ODM customisation.

Competitive Motorsport and Cycling Widely used on road bikes and racing motorbikes for water bottle cages, cable guides and fairing mountings. Ideal where grams and durability count, the aerodynamic button head and vibration resistance.

Commercial Drones & UAV’s: Titanium bolts connect motor mounts and chassis plates to optimize flight duration by minimizing fastener weight. It can withstand high frequency vibration and G-force loadings without fatigue failure.

Marine and Chemical Processing Equipment: ISO7380 m5x10mm titanium bolts are immune to the crevice corrosion that kills stainless steel counterparts, so sensor housings and exterior casings stay sealed throughout lengthy service cycles in subsea robotics and chemical dosing systems.

General Automotive and Machinery These fasteners provide long-lasting performance wherever lower rotational mass and corrosion resistance are needed.

Material Features

Baoji Huacan is in Baoji, Shaanxi, the”Titanium Valley” and the center of China’s titanium industry. We have more than 40 CNC lathes, machining centers and gantry systems to make high precision components.

The annual capacity is around 1,000 tons of finished titanium components. We are just as adept at supporting prototype development, small batch orders and large volume delivery, making us a trusted long-term partner for B2B procurement.

Every bolt starts with certified Ti-6Al-4V bar stock, verified for chemical composition before entering production. CNC precision turning shapes the shank, thread, and button head geometry with tight dimensional tolerances.

Thread machining follows ISO metric standards, with Go/No-Go gauge verification at each batch. Our 40+ CNC lathes and machining centers allow consistent production across prototype, small batch, and mass production volumes.

Post-machining, bolts undergo surface treatment — burnt blue anodizing or mechanical polishing — based on your specification. Each finished part is cleaned, deburred, and inspected before packaging.

Quality is verified at every production stage, not just at final inspection.

Raw Material: Incoming Ti-6Al-4V is tested via XRF spectrometry to confirm alloy composition (Al ~6%, V ~4%) and prevent material substitution.

In-Process: Dimensional checks and thread verification using Go/No-Go gauges (6g tolerance class) are performed throughout machining.

Finished Parts: CMM-based dimensional inspection, surface roughness measurement, and visual checks for burrs, laps, and socket defects are completed before release.

Documentation: Full material traceability records, inspection reports, and material test certificates (MTC / EN 10204 3.1) are available upon request.

Certifications

Our manufacturing plant is ISO 9001 certified for quality management system including raw material purchase, production, inspection and delivery. This guarantees that every batch of fasteners is produced to uniform, traceable quality standards.

For each order material certifications according to EN 10204 3.1 as well as certificates of conformity (COC) are available.

Packaging Type	Description
Custom Foam Inserts	Protection for precision components during transit
Vacuum Sealed Bags	Moisture-proof with desiccants included
Wooden Crates	Suitable for bulk shipments
Labeling & Documentation	Full traceability labeling on every package

We offer air freight for urgent orders and sea freight for cost-effective bulk shipments, with flexible delivery options based on your timeline.

Q: What torque should I apply to these bolts?

A：Use approximately 70–80% of the torque specified for an equivalent steel bolt. Titanium has a lower elastic modulus, and button heads have shallower sockets, so over-torquing risks yielding. Always use a calibrated torque wrench.

Q: Will titanium bolts gall when paired with titanium nuts?

A：Yes. Titanium-on-titanium contact can cause galling (cold welding). Always apply an anti-seize compound — copper paste or moly grease — before assembly.

Q: How do I verify I'm receiving genuine titanium fasteners?

A：Titanium is non-magnetic and roughly half the weight of stainless steel. Request an EN 10204 3.1 material certificate for definitive verification. We provide full material documentation with every order.

Q: Can you supply custom lengths or surface finishes?

A：Yes. We support full customization based on your drawings or specifications, including thread, length, finish, and material grade.

Q: Are these bolts suitable for carbon fiber assemblies?

A：Titanium is galvanically compatible with carbon fiber — a key reason why the product are the preferred fastener for carbon composite structures in motorsport and aerospace.
