Titanium Flat Head Screws
Say goodbye to rust and corrosion—titanium flat head screws last longer, stay stronger, and keep your projects safe even in the harshest environments.
Titanium flat head screws specifications
- ISO 10642 / DIN 7991
- ASME B18.6.3
- ASME B18.3
- ISO 7046-2
We supply every order with EN 10204 3.1 material certificates, RoHS/REACH compliance statements, certificates of conformity (COC), and HS code documents for customs clearance.
Each batch of titanium flat head screws is traceable by heat number and origin, ensuring full quality assurance and regulatory compliance.
Why choose titanium flat head screws
- Grade 5 titanium alloy offers high strength while being about 40% lighter than steel.
- Outstanding corrosion resistance in seawater and harsh chemical environments.
- Countersunk design sits flush with the surface, avoiding scratches or interference.
- Non-magnetic, making it ideal for medical and electronic equipment.
- Reliable performance even at temperatures up to 400 °C.

Titanium grades available
As a leading manufacturer of titanium flat head socket screws, we supply multiple titanium grades tailored to your application needs.
| Grade | Key properties | Typical applications |
|---|---|---|
| Gr2 (Commercially pure titanium) | Excellent corrosion resistance, good formability, cost-effective | Marine, chemical, general industry |
| Gr5 (Ti-6Al-4V, aerospace grade) | High strength-to-weight ratio, lightweight, seawater/chemical resistant, non-magnetic, roll-thread capable | Aerospace, motorsport, composite assembly |
| Gr7 (Ti-0.2Pd) | Superior corrosion resistance in strong acid and chloride environments | Chemical processing, desalination, offshore equipment |
Titanium flat head screws applications
Titanium flat head screws combine flush design, high strength-to-weight ratio, corrosion resistance, and biocompatibility. These features make them widely used across demanding industries.
Aerospace & motorsport
Flush countersunk design reduces aerodynamic drag. Common in skins, ducts, panels, and composite structures for UAVs, race cars, and bicycles.
Marine & offshore
Outstanding resistance to seawater and chlorides. Ideal for ships, offshore platforms, and desalination systems.
Medical & precision instruments
Biocompatible, non-toxic, and non-magnetic. Used in implantable devices such as pacemakers, defibrillators, drug pumps, bone growth stimulators, LVADs, and neurostimulators. Also trusted in clean labs and surgical instruments.
Electronics & industrial equipment
Non-magnetic and corrosion-resistant. Applied in battery packs, electronic housings, and precision measuring devices.
Composites & advanced manufacturing
100° countersunk option reduces delamination and stress concentration. Often paired with carbon fiber laminates in aerospace and automotive assembly.

Frequently asked questions (FAQ)
Q1: What are the disadvantages of titanium screws?
A1: Higher cost, harder to machine, slightly longer lead times.
Q2: Why do people still use flat head screws?
A2: They sit flush with the surface, prevent snagging, and save space.
Q3: Are titanium screws better than steel?
A3: Yes — lighter, stronger for weight, corrosion resistant, non-magnetic.
Q4: What are titanium screws used for?
A4: Aerospace, racing, marine, medical, electronics, composites.
Q5: How to choose 82° / 90° / 100°?
A5: 82° for US thin-wall, 90° for international standard, 100° for aerospace/composites.
Q6: How to prevent galling?
A6: Apply anti-seize, tighten by torque chart, avoid dry assembly.
