RMRC M3 Hardware Pack - 12.9 Grade, 7 Screw Sizes (460 Pcs) - Button Head
by RMRC

The RMRC M3 Hardware Pack (460 Pcs) - Button Head is a premium, high-strength fastener collection engineered specifically for FPV drone builders, RC enthusiasts, and custom robotics modelers. Unlike standard socket head screws that feature a tall profile, button head screws provide a low-profile, domed head design that offers a wider clamping surface while minimizing the risk of snagging or puncturing internal components like LiPo batteries and delicate wiring. This kit is manufactured from 12.9 Grade Alloy Steel, ensuring industrial-grade tensile strength and excellent resistance to stripping under heavy torque compared to standard steel alternatives.

The collection is neatly organized in a transparent, partitioned case with a detailed layout guide affixed to the inner lid, making it highly portable and field-ready for bench builds or quick trackside repairs.
