Original Makita thumb screw (125542-4) — Thumb Screw M10 x 115 mm assembly designed to restore the fine-height/depth adjustment on compatible Makita routers. Listed in Makita parts diagrams as the M10x115 thumb-screw assembly, it features a knurled thumb head for tool-free tightening and a thread that engages an M10 nut or nylon nut on the depth collar. Listed in Makita parts documentation.
Fits several Makita plunge and fixed-base routers including models in the RP1800 / RP1800F /RP1801F / RP1802F / RP1802 / RP1802F / RP1803 / RP1803F / RP2300FC / RP2303FC / RP2302FC and RP2301FC- where the M10x115 thumb screw is used for the height/depth adjuster.
