3Racing M3x18 Titanium Button Head Screws

Keep your RC chassis secure with 3Racing M3 x 18 Titanium Button Head Hex Socket screws, a self-tapping design built from lightweight, corrosion-resistant titanium. The rounded button head profile provides a low-profile, clean look while distributing clamping load evenly across mounting points, making these a popular hop-up choice for touring cars, drift chassis, and competition builds.

The self-tapping design cuts its own threads into plastic and composite components, giving you a secure, wobble-free hold without needing to pre-tap every mounting hole — a real time-saver during builds and repairs. The hex socket drive works with a standard metric Allen wrench for confident, no-slip installation.

At 18mm in length, this size is well suited for thicker mounting points and multi-layer assemblies where a longer screw is needed to reach through several components securely. Titanium's strength-to-weight advantage over steel makes it a favorite among racers looking to trim grams without compromising reliability.

Whether you're building a new chassis or performing routine maintenance, these screws are a dependable, lightweight upgrade for any RC platform using standard M3 hardware. Keep a pack on hand in your pit box for quick fixes and hop-ups.
