12.9 Grade Black Nickel Screws — Button Head & Countersunk (M2/M2.5/M3)

These 12.9 grade metric screws are for FPV builds that need high-strength fasteners in M2, M2.5 or M3 sizes. Use the button-head variants where you want a compact top profile, or the countersunk variants where the part is meant to sit flush. Pick the length to match plate thickness, standoff height and thread engagement in your frame, stack or accessory mount.
