Original Makita part 0119069720 — socket‑head bolt (M6 × 14 mm). This genuine Makita hex‑socket cap screw is a 6 mm thread diameter, 14 mm shank length fastener (socket / Allen head) used on Makita brush‑cutter assemblies. It’s the direct replacement fastener shown for models such as the RBC421L and MS4211, so it’s ideal when a lost or damaged bolt is preventing you from reassembling the guard, handle or related hardware.
