Genuine Makita flat H (fillister) square‑neck bolt 266405‑6 — M6 × 75 mm — steel fastening bolt designed to match the original factory dimensions and fitment on Makita metal‑cutting saws. The square neck locks into the mating slot to prevent rotation while you tighten the M6 threaded shank, and the flat / fillister head gives a low profile finish where space is limited. Ideal as a single replacement part to restore correct alignment and secure mounting of guards, bases or blade assemblies; sold individually. Compatible with models that use this part in their exploded parts lists, for example BCS550, BSS500, BSS501 and DCS550 (including DCS550RMJ / DCS550Z) — an original Makita component that provides a direct, like‑for‑like repair. This genuine Makita piece is the exact match you want when replacing small but critical power tool parts.
