MultiMaster owners did you loose the Retainer Bolt that secures the blades onto your 250Q or 350Q model?
This Retainer replaces your lost bolt or serves as a convenient back-up.
This blade and accessory Retainer is exactly the same as the one that comes with the new unit.
This Fein replacement mounting bolt works only on MultiMaster models:
