Makita JM23100141 Spare Part - LOCKNUT M5

Original Makita lock nut — part number JM23100141 — a precision M5 lock nut used to secure moving assemblies on Makita slide/compound mitre saws.

This single replacement part is listed as compatible with models such as the LS1018 / LS1018L and LS0815F / LS0815FL, and is also shown in parts listings for several other LS-series saws (check your model’s parts diagram to confirm the exact location).

The nut holds blade/guard or linkage components firmly in place and is designed to resist loosening from vibration during cutting — a small but critical fastener when restoring alignment and safe operation. If you need a genuine component from Makita spare parts to get the saw back to proper function, this original Makita lock nut is the correct direct-fit replacement.

Sold individually and ready to install in place of a lost or damaged lock nut; refer to your machine’s exploded parts diagram or the part number JM23100141 to verify fit before ordering.
