The knife-holder pin, model 32, Aghetto brand is the threaded pin that, in the mincing assembly of a size-32 meat grinder, mounts the cross blade and keeps it in register. Screwed onto the worm/auger, it drives the blade against the perforated plate: it is therefore a drive and centring component, subject to continuous stress and wear during mincing.

The part has a 15x15 square that engages the cross blade to transmit rotation, and a Ø 13 mm round section for guiding/centring; the threaded portion is M22 with a 2.5 mm pitch and the total pin length is 55 mm.

When to replace it: the pin should be changed when the M22 thread is stripped, when the 15x15 square is rounded/worn (the blade slips and no longer cuts cleanly), or when the pin is bent and creates play. A worn pin spoils the quality of the mince and can damage both the blade and the plate.
