Traxxas 3929 Screws 4x18mm Button-Head

Button-head machine screws, 4x18mm, hex drive. Six per package.

Button-head screws spread clamping load over a wider area than a cap head, which is why Traxxas uses them where the fastener seats against composite rather than metal. At 4mm diameter these are among the larger fasteners on the car and typically carry higher-load mounting duties.

Hex heads round out with repeated use, especially if a slightly worn driver is used, so a fresh set is worth keeping on the shelf before you need it.

Fits: Traxxas XO-1 (64077-3) and other Traxxas models using 4x18mm button-head hardware.

Direct replacement for the factory screws.
