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.
