⚙️ Product Overview: TA2 Titanium Phillips Cross Pan Head Machine Screws – M1.4 to M4
If you're building lightweight drones, racing bicycles, medical devices, or marine equipment, you need fasteners that are strong, light, and corrosion‑proof. These TA2 grade titanium Phillips pan head machine screws deliver exactly that – about 45% lighter than steel with strength comparable to Grade 5 alloys. The cross pan head (Phillips drive) allows for easy installation with standard bits, while the low‑profile rounded head distributes clamping force evenly. Made from pure TA2 titanium (Grade 2), they offer exceptional corrosion resistance, biocompatibility, and durability. Available in micro sizes M1.4, M1.6, M2, M3, and M4. Fully threaded with standard coarse metric pitch. Perfect for aerospace, medical implants, automotive, marine, and high‑performance DIY projects.
✨ Why TA2 Titanium Phillips Pan Head Screws Are a Performance Upgrade
-
TA2 pure titanium (Grade 2) – Excellent strength‑to‑weight ratio. Higher strength than many steels at roughly half the weight. Superior corrosion resistance in saltwater and chemical environments.
-
Phillips cross pan head design – Low‑profile rounded head provides a clean, professional finish. Cross recess works with standard PH0, PH1, or PH2 bits for easy installation.
-
Exceptional corrosion resistance – Titanium naturally resists rust, saltwater, and most acids. Outperforms stainless steel in harsh marine and chemical environments.
-
Biocompatible & non‑magnetic – Safe for medical implants and sensitive electronic equipment. No magnetic interference.
-
Micro metric sizes M1.4, M1.6, M2, M3, M4 – Covers the most common tiny diameters for watches, drones, medical instruments, and precision electronics.
-
Fully threaded, coarse metric pitch – Standard threads per size. Threads run the entire shank length for maximum grip in thin materials.
-
Wide application range – Aerospace, medical devices, automotive, marine, sporting goods (bicycles, racing equipment), and high‑end consumer electronics.
-
Long‑term reliability – Titanium's fatigue resistance and durability reduce the need for frequent replacements, making it cost‑effective over time.

❓ FAQs – TA2 Titanium Phillips Pan Head Screws
🔸 How do TA2 titanium screws compare to 304 or 316 stainless steel?
TA2 titanium is about 45% lighter than stainless steel while offering similar or higher tensile strength (>750MPa vs ~550MPa for 316). It provides superior corrosion resistance, especially in saltwater and chemical environments. Titanium is also non‑magnetic and biocompatible. The main trade‑off is cost – titanium is more expensive, but for weight‑critical and high‑performance applications, it's worth every gram saved.
🔸 Are these screws fully threaded? How is length measured?
Yes – they are fully threaded from just under the head to the tip. Length is measured from the underside of the head (the flat bearing surface) to the tip, not including the pan head. For example, an M3 x 12mm screw has a 12mm threaded shank.
🔸 Will titanium screws gall or seize when installed?
Titanium can gall (cold weld) if installed dry, especially into titanium nuts or threaded holes. We recommend using an anti‑seize lubricant (copper paste or titanium‑specific grease) on the threads – this is standard practice in aerospace and motorsports. For steel or aluminum nuts, galling is less likely but lubricant is still good practice.
🔸 What Phillips screwdriver size works for M1.4 through M4?
M1.4–M2: use PH00 or PH0 (PH00 is safest). M3: use PH0 or PH1. M4: use PH1. A precision screwdriver set with sharp, properly sized bits is essential to avoid stripping the small recesses.
🔸 Can I use these screws with nuts, or are they self‑tapping?
These are standard machine screws – they require a matching metric nut (M1.4–M4) or a pre‑tapped hole. They are not self‑tapping. For best results, use titanium or stainless steel nuts with anti‑seize on titanium‑to‑titanium threads.
🔸 What applications are these tiny titanium screws best suited for?
These micro sizes are ideal for drones and UAVs, RC cars and planes, watches and eyeglasses, medical implants and surgical instruments, dental devices, bicycle components (derailleur adjustment, small brackets), marine electronics, and high‑end consumer electronics where weight and corrosion resistance are critical.
