Key Features
- Super-tough Material Construction — These screws are manufactured from hardened steel designed to withstand the demanding forces experienced in modern RC vehicles, ensuring they won't strip, shear or fail prematurely during normal operation or maintenance cycles.
- Precision Hex Head Design — The precision-engineered hex head provides a perfect grip for your hex driver, eliminating wobble and the risk of damaging the screw head during installation or removal, which is critical when working with delicate RC components.
- Precision Thread Profile — The precisely cut thread pattern ensures smooth fastening and a secure hold that remains tight even through vibration and high-impact use typical of RC racing and bashing.
- M3x8mm Specification — This exact size is widely used across the ARRMA range, making these screws highly compatible with numerous vehicles in the lineup from entry-level brushed trucks to top-tier brushless 8S models.
- Button Head Profile — The low-profile button head design sits flush against components without protruding excessively, important for maintaining proper fitment in tight spaces on RC chassis and body panels.
- Pack of 10 Screws — Each pack contains 10 individual fasteners, providing adequate spares for replacement, repair, and maintenance of your RC collection without needing to order frequently.
Technical Performance
The ARRMA Button Head Screw 3x8mm represents the kind of attention to detail that separates genuine OEM parts from generic aftermarket alternatives. These fasteners are engineered to withstand the rigorous demands placed on RC vehicles operating at high speeds, over challenging terrain, and through repeated impact cycles. The M3 diameter with 8mm length places them in a size range that offers optimal balance between strength and weight, critical considerations in RC vehicle design where every gram matters. The precision hex head accommodates standard 2.0mm hex drivers, and the machine thread pattern ensures compatibility across the entire ARRMA ecosystem. Whether you are maintaining a 1/10 scale brushless monster truck delivering raw acceleration and power, a nimble 2WD short course truck optimised for tight racing circuits, or a 1/8 scale high-performance buggy, these screws provide the fastening solution engineered for the job. The hardened steel composition resists stripping and deformation, maintaining structural integrity through countless assembly and disassembly cycles that are part of regular RC maintenance and tuning.
