Fein 40242064000 — Genuine Fein straight (cylindrical) pin for MultiMaster/multi‑tool repairs. This precision-turned dowel is the locating/retaining pin used in the oscillating linkage; it replaces the worn or sheared pin that can allow excessive play or mis‑indexing of the blade holder. Ideal when you need a single replacement part to restore proper alignment — a small but critical item among power tool parts for repair.

Example Fein models this part is listed to fit include (non‑exhaustive): FMM350Q, FMM350QSL, FMM250Q, AFMM14 (14.4 V), AFMM18 (18 V), and FSC 1.6 Q / FSC 2.0 Q MultiMaster / MultiTalent variants (the pin appears as position 490 in Fein exploded parts diagrams). Please check your tool’s type/model number against the parts list or diagram to confirm compatibility before installing.
