⚙️ Product Overview: M5 & M8 Titanium Socket Cap Head Torx Screws – Grade 10.9, 10–60mm
For high‑performance applications where weight savings, strength, and corrosion resistance are critical, these titanium socket cap head Torx screws are an outstanding choice. Made from premium titanium alloy, they offer exceptional strength‑to‑weight ratio – significantly lighter than steel while maintaining Grade 10.9 strength. The Torx (star) drive provides superior torque transfer and eliminates cam‑out, allowing you to tighten securely without stripping. The low‑profile socket cap head is designed for counterbored holes, leaving a clean, flush finish. Available in M5 and M8 metric diameters with lengths from 10mm to 60mm (measured under the head). Perfect for automotive, motorcycle, bicycle, marine, furniture, and outdoor equipment where reliability and reduced weight matter.
✨ Why Upgrade to Titanium Torx Socket Cap Screws
-
High‑grade titanium construction – Excellent strength‑to‑weight ratio. Stronger than many steels yet about 45% lighter. Grade 10.9 strength equivalent.
-
Torx (star) drive – The six‑lobe internal recess provides full contact engagement, eliminates cam‑out, and allows high torque without stripping the drive.
-
Socket cap head (cylindrical) – Low‑profile, clean appearance. Designed for counterbored holes, leaving a flush or recessed finish.
-
Metric sizes M5 and M8 – Versatile diameters for automotive, motorcycle, bicycle, marine, furniture, and industrial applications.
-
Lengths from 10mm to 60mm (under head) – Short screws for thin brackets, longer ones for structural assemblies. Choose exactly what your project needs.
-
Fully threaded, coarse metric pitch – Standard threads: M5x0.8, M8x1.25. Threads run the entire shank length for maximum grip.
-
Superior corrosion resistance – Titanium naturally resists rust, saltwater, and chemicals – outperforms stainless steel in many harsh environments.
-
High temperature resistance – Maintains strength and stability at elevated temperatures, suitable for engine compartments and exhaust systems.

❓ FAQs – Titanium Torx Socket Cap Screws
🔸 How do titanium screws compare to stainless steel in terms of strength and weight?
Titanium has a tensile strength comparable to high‑grade stainless steel (Grade 10.9 vs A2-70) but at roughly 45% less weight. 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 is more expensive, but for performance applications (racing, marine, aerospace), the weight savings and longevity are well worth it.
🔸 What Torx bit size do I need for M5 and M8?
M5 typically uses a T25 Torx bit. M8 uses a T30 or T40 (depending on head design). A quality Torx bit set (T20–T45) will cover both. Always check fit before applying torque to avoid damaging the recess.
🔸 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 socket cap head. For example, an M8 x 40mm screw has a 40mm 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.
🔸 Can I use these screws with nuts, or are they for tapped holes only?
These are standard machine screws – they work with matching metric nuts (M5 or M8) or in pre‑tapped holes. For best corrosion compatibility, use titanium or stainless steel nuts (with anti‑seize on titanium‑to‑titanium threads).
🔸 What lengths are available for M5 and M8?
We offer lengths from 10mm to 60mm. Typical increments: 10, 12, 16, 20, 25, 30, 35, 40, 45, 50, 60mm. Please select your desired length from the dropdown options. If you need a length not listed, contact us.
