⚙️ Product Overview: TA2/GR2 Pure Titanium Phillips Countersunk Screws – M2 to M10 (DIN 965)
If you're building high‑end racing bikes, drones, marine equipment, or medical devices, you already know that weight savings and corrosion resistance matter. These TA2 pure titanium Phillips countersunk machine screws deliver exactly that – strength comparable to steel at roughly half the weight, plus unmatched resistance to saltwater and chemicals. The flat 90° head sinks flush for a clean, aerodynamic finish, and the Phillips drive makes installation easy with standard bits. Available in metric sizes from M2 up to M10, fully threaded to DIN 965 standards with coarse metric pitch. Cold‑formed for consistent grain structure, these Grade 4.8 titanium bolts are a true upgrade over stainless steel for anyone serious about performance and longevity.
✨ Why Upgrade to TA2 Pure Titanium Countersunk Screws
-
TA2 pure titanium (Grade 2) – Excellent mechanical properties: tensile strength >750MPa, yield strength >500MPa. Stronger than many steels yet about 45% lighter.
-
Superior corrosion resistance – Outperforms 316 stainless in saltwater, chemical, and marine environments. Naturally rust‑proof and biocompatible – ideal for medical and aerospace applications.
-
Phillips countersunk flat head (DIN 965) – Sits flush in tapered holes for a smooth, snag‑free surface. Professional finish for visible assemblies.
-
Wide size range: M2, M2.5, M3, M4, M5, M6, M8, M10 – From tiny electronics fasteners up to structural bolts for motorcycles, drones, and marine rigging.

❓ FAQs – TA2 Titanium Countersunk Phillips Screws
🔸 How does TA2 titanium compare to 316 stainless steel for screws?
TA2 titanium is about 45% lighter than stainless steel, yet it has higher strength (tensile >750MPa vs ~550MPa for 316). It also offers superior corrosion resistance, especially in saltwater and chemical environments. Titanium is non‑magnetic and biocompatible. The main trade‑off is cost – titanium screws are more expensive, but for high‑performance applications (racing, marine, medical), they're 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 as total screw length including the head (standard for countersunk fasteners). For example, an M5 x 20mm screw is 20mm long overall from the top of the flat head to the tip. Countersunk holes should be drilled to match this total depth.
🔸 Will titanium screws gall or seize like stainless steel?
Titanium can gall (cold weld) when installed dry, especially into titanium nuts or at high speeds. We strongly recommend using an anti‑seize lubricant (copper paste or titanium‑specific grease) when driving titanium screws. This prevents galling and ensures easy future removal – a common practice in aerospace and racing industries.
🔸 What Phillips screwdriver size works for M2 through M10?
M2–M2.5: use PH0 or PH00. M3–M4: use PH1. M5–M6: use PH2. M8–M10: use PH2 or PH3 (PH2 works for most). Using the correct size prevents stripping – titanium is tough, so good bit fit is essential.
🔸 Can I use these screws with nuts, or are they self‑tapping?
These are standard machine screws – they require a matching metric nut (M2–M10) or a pre‑tapped hole. They are not self‑tapping. For best corrosion compatibility, use titanium or stainless steel nuts (with anti‑seize on titanium‑to‑titanium threads).
🔸 What applications are TA2 titanium screws best suited for?
Aerospace (drones, aircraft interiors), motorsports (motorcycles, racing bicycles), marine (boat hardware, diving gear), medical (implants, surgical instruments – though certified medical grade is separate), chemical processing, high‑end consumer electronics, and any weight‑critical, corrosion‑sensitive project where only the best will do.
