Makita 416286-0 — Lock Button (original Makita part). A small molded lock button used in the handle/gearbox area to engage and hold the change lever/slide sleeve on SDS‑max rotary hammers; listed in Makita parts breakdowns as item 416286-0.

Fits several Makita rotary hammers — commonly shown for HR4000C and HR5001C (and listed alongside HR4000/4500 series parts in official diagrams and parts lists). If you’re repairing a Makita HR4000C or HR5001C, this genuine Makita spare part restores the original lock‑button function.

Compact, inexpensive and sold as a single replacement button — a direct drop‑in for the lock‑button location on the models above when the original is worn, cracked or missing.
