Knife pin for the Fimar model 12 meat mincer. This is the central pin fitted onto the end of the mincer's worm screw (auger), onto which the knife and perforated plates are mounted and then locked in place with the ring nut.

• Compatibility: Fimar model 12 meat mincer
• Function: supports and centers the knife/plate assembly on the auger shaft

Replace it when the pin is bent, worn in the knife seat, or no longer holds the knife and plate firmly, causing axial play, uneven mincing of the meat, or a risk of the ring nut loosening during operation. It is a key component for the seal and safety of the mincer assembly.
