ARRMA ARA727412 Flanged Button Head Screw M4x18mm

These high-quality M4x18mm flanged button head screws provide ideal replacement hardware for your kit-supplied items. The flanged head design spreads clamping load over a wider area than a standard button head — the 9.6mm flange seats securely against composite parts without digging in, which is exactly why ARRMA specs this fastener at high-stress mounting points across its vehicle lineup, including Felony and Infraction chassis applications.

Each screw is made from strong, durable steel for long-lasting performance, with precision manufactured threads for a consistent fit and fast servicing. Clean threads matter on a basher: they thread in straight, torque down predictably, and come back out without stripping when it's time to wrench again.

Specification is M4 x 18mm — metric 4mm diameter with an 18mm thread length — in the flanged button head configuration. Keeping a pack of these in the pit box means a lost or rounded-out screw never ends a run day.

The package includes four M4x18mm button head flanged screws.
