⚙️ Product Overview: Titanium Phillips Countersunk Flat Head Screws – M1.6 to M6 (TA2 / Grade 2)
If you're building a lightweight race bike, a drone, or any project where every gram counts but strength can't be compromised, these TA2 pure titanium Phillips countersunk flat head screws are exactly what you need. Titanium is stronger than steel at half the weight, naturally resists acid and corrosion better than stainless, and has a unique flexibility that absorbs vibration without snapping. The flat 90° head sinks flush into countersunk holes for a clean, aerodynamic finish, while the Phillips drive works with standard bits. Available in micro sizes from M1.6 up to M6, and lengths from 4mm to 50mm – fully threaded with coarse metric pitch. Made from Grade 2 (TA2) pure titanium, these bolts are a favorite among automotive, motorsport, and marine builders who demand the best.
✨ Why Titanium Countersunk Phillips Screws Outperform Steel and Stainless
-
Pure TA2 titanium (Grade 2) – Exceptional corrosion and acid resistance. Outperforms 316 stainless in saltwater and chemical environments. Naturally rust‑proof.
-
Ultra‑lightweight yet strong – Titanium has the strength of steel at roughly half the weight. Ideal for weight‑sensitive builds like bikes, drones, and racing equipment.
-
Inherent flexibility – Unlike brittle stainless, titanium has a natural springiness that absorbs shock and vibration without cracking or loosening.
-
Phillips countersunk flat head – Sits flush in tapered holes for a smooth, snag‑free finish. Aerodynamic and professional.
-
Wide size range: M1.6, M2, M3, M4, M5, M6 – From tiny electronics and watches up to structural fasteners for motorcycles and marine gear.
-
Lengths from 4mm to 50mm (under head) – Extensive selection: 4, 5, 6, 8, 10, 12, 16, 18, 20, 25, 30, 35, 40, 45, 50mm. Choose exactly what you need.
-
Fully threaded, coarse metric pitch – Standard threads run the entire shank length for maximum grip and easy nut engagement.
-
Natural titanium color – Distinctive metallic gray that looks great on custom builds and high‑end equipment.

❓ FAQs – Titanium Countersunk Phillips Screws
🔸 What makes titanium better than stainless steel for screws?
Titanium is about 45% lighter than steel yet just as strong. It has superior corrosion resistance – even better than 316 stainless in saltwater. Titanium is also non‑magnetic, hypoallergenic, and has natural flexibility that resists fatigue and vibration loosening. For race cars, bikes, and marine use, it's the ultimate fastener material.
🔸 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 head. For example, an M5 x 20mm screw has a 20mm threaded shank.
🔸 Will titanium screws gall or seize like stainless steel?
Titanium can gall (cold weld) if installed dry at high speed. We recommend using an anti‑seize lubricant (like copper paste or titanium‑specific grease) when driving titanium screws, especially into titanium nuts or threaded holes. This prevents galling and ensures easy future removal.
🔸 What Phillips screwdriver size works for M1.6 through M6?
M1.6–M2: use PH0 or PH00. M3–M4: use PH1. M5–M6: use PH2. Using the correct size prevents stripping. A precision screwdriver set is recommended for the smallest sizes.
🔸 Can I use these screws with nuts, or are they self‑tapping?
These are standard machine screws – they require a matching metric nut (M1.6–M6) or a pre‑tapped hole. They are not self‑tapping. For best results, use titanium or stainless nuts with anti‑seize lubricant.
🔸 Are these screws magnetic? Will they work near sensitive electronics or MRI machines?
Titanium is completely non‑magnetic. It's an excellent choice for medical devices, MRI rooms, compass housings, and high‑end audio equipment where magnetism would cause interference.
