ARRMA ARAC9804 Button Head Screw M3x28mm

These high-quality M3x28mm button head hex machine screws are the perfect replacement hardware for kit-supplied fasteners on ARRMA vehicles. The M3x28mm spec — metric 3mm thread with a 28mm length — is a standard kit fastener across multiple ARRMA platforms, used at deeper mounting points like shock towers and gearbox cases where a long reach is required.

Each screw is made from super-strong steel for long-lasting durability and consistent fitting, with precision manufactured threads for fast, easy maintenance. Clean threads matter over the life of a basher: they seat straight, torque predictably, and come back out without stripping the hex socket after multiple teardowns.

With ten screws per pack, this is genuine pit-box stock rather than a single-repair purchase — hardware disappears constantly between crashes, grass, and bench sessions, and ARRMA bags these in multiples so a missing screw never stalls a rebuild.

This part carries the legacy ARRMA number AR721328 under the Horizon Hobby ARAC9804 ordering number. The package includes ten M3x28mm button head hex machine screws.
