Note: JM23000074 is a Makita part number, not a Hitachi part.

Original Makita JM23000074 — Square‑neck bolt M6 × 10 mm. This is the genuine Makita square‑neck fastening bolt (M6 thread, 10 mm length) specified for use in the 255 mm compound/mitre saw assemblies. It’s sold as a single replacement fastener and listed on the parts breakdown as "SQUARE NECK BOLT M6X10."

Fits (examples): Makita MLS100 (255 mm mitre saw) and Makita M2300 (255 mm compound mitre saw) - If your saw’s parts diagram shows JM23000074 (or the square‑neck M6×10 at the same position), this is the direct, original replacement.

Use notes: the square neck is intended to seat into a matching square hole or slot so the bolt won’t turn while tightening; replace if the original is corroded, the square shoulder is damaged, or the thread is worn. Supplied as the single bolt shown on the official parts list.
