You’re working on a lightweight racing drone, a medical implant prototype, or a marine component that needs to survive salt spray – and steel is too heavy or prone to rust. These TA2 pure titanium pan head screws offer the best of both worlds: they’re as strong as many steels but about 40% lighter, and they’re completely rust‑proof. The Pozidriv (Pozi) cross recess gives you a firm, non‑cam‑out drive. Available in M1.6 through M6 diameters, with lengths from 2mm to 50mm (under head). Fully threaded. Perfect for aerospace, motorsports, chemical equipment, and any project where high strength, low weight, and corrosion resistance matter.
| Thread Diameter (M) | Thread Pitch (mm) | Length Range (mm, under head) * | Head Style | Drive | Material |
|---|---|---|---|---|---|
| M1.6 | 0.35 | 2, 3, 4, 5, 6, 8, 10, 12, 16, 20, 25, 30, 35, 40, 45, 50 (exact availability varies by diameter) |

* Length measured from underside of head to tip (grip length). All screws fully threaded. Pozidriv bit size: PZ0 for M1.6–M2.5, PZ1 for M3–M6.
| Property | TA2 Titanium | 304 Stainless Steel |
|---|---|---|
| Density | 4.51 g/cm³ (≈40% lighter) | 7.93 g/cm³ |
| Tensile strength | ~750 MPa | ~700 MPa |
| Corrosion resistance | Superior – immune to saltwater, chlorides, many acids | Good – but pitting in saltwater |
| Magnetic | Non‑magnetic | Almost non‑magnetic (slight after cold working) |
| Biocompatibility | Excellent – used for medical implants | Limited (some nickel sensitivity) |
1. Are these screws strong enough for structural use?
Absolutely. TA2 titanium has higher tensile strength than 304 stainless steel (750 vs 700 MPa). Combined with low weight, they’re ideal for aircraft, racing, and high‑performance structures where both strength and weight matter.
2. Will titanium screws rust or corrode in saltwater?
No – titanium is one of the most corrosion‑resistant metals. It’s completely immune to saltwater and chloride attack. Perfect for marine hardware, boat fittings, and offshore equipment.
3. Can I use these screws with a power tool?
Yes – titanium is strong and not brittle. However, use a low‑clutch setting to avoid stripping the Pozi recess. Hand tightening is recommended for final torque.
4. Are these screws fully threaded? How do I measure length?
Yes – all are fully threaded. For pan head screws, length is measured from the underside of the head to the tip. The head itself is NOT included. So an “M3 x 10mm” screw has a 10mm threaded shaft under the head.
5. Do you offer matching titanium nuts or washers?
We currently focus on screws, but we can source titanium nuts and washers on request. Contact us for custom orders.
6. Is TA2 titanium biocompatible? Can I use these for medical devices?
Yes – TA2 is commercially pure titanium, widely used for surgical implants and medical instruments. It’s non‑toxic and hypoallergenic. However, for sterile medical use, ensure proper cleaning and packaging – contact us for certified medical‑grade fasteners.
