Original Makita flat washer — part number JM23100016. This small, low-profile flat washer (listed as "Flat Washer 4") is the exact replacement washer used on several Makita slide/compound mitre saw assemblies.
Why this part matters: it secures M4‑size fastenings and pivot/shelf components in the saw’s base and linkage so blades and scales stay aligned and wobble-free (the part is listed in exploded parts diagrams as "Flat Washer 4," which indicates use with M4 fasteners).
Example Makita models that use JM23100016: LS1018 / LS1018L, LS0815FL (and related LS08 series machines), and several LS1110/LS1110F variants — consult your model’s parts diagram to confirm the washer location before installation.
Quick notes for fit and use: this is an original Makita replacement part supplied as the machine’s flat washer for M4 fasteners; it’s intended to replace lost, damaged or corroded washers to restore correct fastener clamping and component alignment.
If you need the washer to complete a repair, ordering the JM23100016 ensures you get the same item specified in Makita parts lists for the models above.
