Original Makita JM23100024 — Lock Shaft B (locking pin) designed for Makita slide/compound mitre saws.
This precision locking shaft secures the bevel/mitre locking assembly so the head holds positive stops and repeatable angles; it’s supplied as the single replacement shaft called out in the parts breakdown.
Fits example models including LS1018 and LS1018L (also shown in parts lists for LS1017L-series service documents), so it’s the correct factory replacement when the original lock pin is worn, bent or missing.
An original Makita component made to factory tolerances for reliable engagement with the bevel-lock mechanism — listed and sold as a genuine Makita part for direct replacement.
If you’re ordering a single repair item from Makita parts to restore a saw’s locking action, this JM23100024 lock shaft is the direct-fit power tool parts choice called out in the official diagrams.
