The knife holder pin is the threaded component of the meat mincer's grinding assembly: it screws onto the end of the auger and acts as the shaft on which the cross-shaped knife is mounted against the perforated plate. It holds the knife in position during rotation, ensuring the correct blade–plate contact that produces a clean cut of the meat and prevents crushing or smearing.

This pin is specific to NSV brand meat mincers, model 22. The model size (22) together with the thread and square dimensions determine compatibility: always check it against the part being replaced before purchase, as model-22 pins from different brands can have different pitch, thread length and flange.

Technical specifications:

• Brand: NSV
• Model: 22
• Thread: 14
• Pitch: 1.5 mm
• Thread length: 21 mm
• Square section: 13x13 mm
• Flange: 20 mm

When to replace it: in case of stripped thread, bent or worn pin, excessive play, or difficulty keeping the knife in contact with the plate. A deformed pin compromises grind quality and accelerates wear of the knife and plate.
