M3 TC4 Titanium Button Head Screws (4pcs)

Premium lightweight hardware for builds where every gram matters.

These M3 TC4 titanium button head screws use the same Ti-6Al-4V family of alloy trusted in aerospace applications: high strength, excellent corrosion resistance, and a clean premium finish without the weight penalty of steel.

• M3 thread
• Button head with hex socket drive
• Sold as one 4-piece set per selected length
• Available lengths: 8mm, 10mm, 12mm, 16mm
• Main image shows all available lengths for comparison

Strength comparison vs our YSF 12.9 steel hardware:

• TC4 / Ti-6Al-4V titanium is published around 900-950 MPa ultimate tensile strength
• Class 12.9 steel is published around 1220 MPa ultimate tensile strength
• So yes: 12.9 steel wins on raw absolute tensile strength
• But titanium is roughly 42-44% lower density than steel, giving it an approximately 31-35% better strength-to-weight ratio

What that means on a real FPV build: if your only goal is maximum absolute bolt strength per dollar, 12.9 steel is the brute-force choice. If you want premium hardware that is still seriously strong while cutting weight and resisting corrosion, TC4 titanium is the better upgrade.

Measured Weight Comparison

Measured on actual screws using a digital scale. The last row compares 8pcs of 16mm titanium against 4pcs of 30mm steel.

Note: each variant is one set of 4 screws in the selected length, not a 16-piece assorted kit.
