Makita 912117-6 — Countersunk head screw (original Makita), M4 × 12 mm. A direct-fit replacement countersunk (flat) head screw used to secure pads, base plates, covers and small internal brackets on Makita finishing sanders and screw-guns. Made to the same specification used in the factory assembly, it gives a flush finish where a low‑profile fastener is required and installs into the original tapped holes with no modifications.
Example models this part is listed for (examples only): BO4556, BO4555, BO4561 and earlier BO45xx finishing sanders; it is also referenced in parts lists for several small Makita screw-guns and cordless drivers such as the BFR/DFR series and select 68xx models. Use this screw where the parts diagram calls out part number 912117-6 or “CSH screw M4×12.”
Sold as the single genuine Makita countersunk screw (part no. 912117-6). Ideal when a lost, stripped or damaged screw is keeping your tool from running true — exact size: metric M4 thread, 12 mm length, countersunk head for a flush fit.
