Perno de titanio M4

M4 titanium bolts machined from Grade 5 Ti-6Al-4V (TC4) — roughly 40% lighter than steel at comparable tensile strength, and naturally corrosion resistant without plating.

This is our smallest thread size, used for pump covers, fairing panels, cable guides, derailleur hardware and other low-load fixings where every gram counts. Lengths run 6mm to 40mm on a 0.7mm pitch, with a 7.5mm flanged Torx head driven by a T20 bit — the flange spreads load so you can skip a separate washer on soft alloy.

Every bolt weighs 1–2g and is available in natural titanium, gold, rainbow, burn blue and black anodised finishes. Prices are per bolt.
