Titanium Phillips Pan Head Machine Screws — Lightweight, Corrosion-Proof, Precision-Threaded

Engineers, hobbyists, and builders who work with weight-sensitive or corrosion-prone assemblies know the frustration of steel screws that rust, seize, or add unnecessary mass. Whether you're building a custom bicycle, assembling RC components, or working on a marine or aerospace project, these TA2 Grade 2 titanium Phillips pan head machine screws deliver the corrosion resistance and weight savings that steel simply can't match.

Each screw is machined from commercially pure TA2 (Grade 2) titanium and features a Phillips pan head drive. Available in thread diameters from M2 to M8 and total lengths from 3mm (≈1/8") to 55mm (≈2.2"), with pack quantities of 1, 10, or 50 pieces per order. The pan head profile provides a broad, low-profile bearing surface ideal for through-hole and countersunk-adjacent applications.

Typical use cases include lightweight bicycle component fastening, RC car and drone frame assembly, electronics enclosure mounting, and marine hardware installation where titanium Phillips pan head screws for corrosion resistance are a practical necessity. The metric ISO thread standard (M2–M8) ensures compatibility with standard tapped holes and metric nuts across a wide range of industries.

🔩 Thread Compatibility: ISO Metric thread standard — M2, M2.5, M3, M4, M5, M6, M8. Not compatible with imperial (UNC/UNF) threads. Verify your tapped hole or nut is metric before ordering.

✅ Key Features of These Titanium Phillips Pan Head Machine Screws

⚖️Lightweight Construction — TA2 titanium is approximately 43% lighter than stainless steel, making these titanium machine screws ideal for weight-critical builds like cycling, motorsport, and drone frames.
🌊Exceptional Corrosion Resistance — The natural titanium oxide layer provides outstanding protection against saltwater, humidity, and chemical exposure — outperforming stainless steel in marine and coastal environments.
🔧Phillips Pan Head Drive — The pan head profile offers a wide, flat bearing surface that distributes clamping load evenly, while the Phillips recess is compatible with standard PH0–PH3 screwdriver bits.
📐Wide Size Range — Available in M2 through M8 thread diameters and lengths from 3mm to 55mm, covering a broad range of fastening needs from precision electronics to structural mechanical assemblies.
🧲Non-Magnetic — Titanium is non-ferromagnetic, making these screws suitable for use near sensitive electronics, MRI-adjacent equipment, and applications where magnetic interference must be avoided.
📦Flexible Pack Quantities — Order 1, 10, or 50 pieces per size to match your project scale — whether you need a single replacement fastener or a bulk supply for production runs.

❓ Frequently Asked Questions

How do I choose the right length for my titanium Phillips pan head screw?

A general rule: the screw length should be roughly 2–3× the thread diameter for most clamping applications. For example, an M3 screw typically works well at 6–10mm (about 1/4"–3/8") for thin panels, and 20–30mm (≈3/4"–1.2") for thicker assemblies. Always account for the full material stack you're fastening through — including washers, spacers, and any surface coatings.

What is the tensile strength of TA2 Grade 2 titanium screws?

TA2 (Grade 2 commercially pure titanium) generally has a tensile strength of approximately 345–485 MPa (50,000–70,000 psi). This is typically sufficient for light-to-medium structural and mechanical applications. For heavy-load or high-stress environments, consider Grade 5 (Ti-6Al-4V) titanium instead.

Are these titanium screws suitable for outdoor or marine use?

Yes. Titanium naturally forms a stable oxide layer that provides excellent corrosion resistance, including in saltwater and humid environments. TA2/Gr2 titanium is generally considered superior to stainless steel in marine and coastal applications where chloride-induced corrosion is a concern. No additional coating or treatment is typically required.

What thread standard do these screws use — metric or imperial?

These screws use the ISO metric thread standard (M2, M2.5, M3, M4, M5, M6, M8). They are not compatible with imperial (UNC/UNF) threaded holes. Always verify your tapped hole or nut is metric before ordering. If you're unsure, a thread gauge or caliper measurement of your existing hardware will confirm the pitch and diameter.

How do I decide between M3, M4, and M5 for my project?

Thread diameter selection depends on the load and the clearance hole in your material. M3 is commonly used in electronics, RC components, and lightweight brackets. M4 suits general mechanical assemblies and bicycle parts. M5 and above are typically used for structural connections, automotive, and heavier equipment. When in doubt, check the manufacturer's recommended fastener size for your application.

What screwdriver bit do I need for Phillips pan head screws?

Phillips pan head screws in M2–M3 typically require a PH0 or PH1 bit. M4–M6 generally use a PH2 bit, and M8 may require a PH3. Using the correct bit size is important to avoid cam-out and head damage, especially with titanium which can be softer than alloy steel. Always use a well-fitting, non-worn bit.

Is titanium lighter than stainless steel?

Yes. Titanium has a density of approximately 4.5 g/cm³ compared to stainless steel at about 7.9 g/cm³ — making titanium roughly 43% lighter. This weight savings is significant in weight-sensitive applications like cycling, aerospace, and motorsport, where every gram matters.
