Description
Overview:
The Crown Nut M30 is a heavy-duty castellated fastening nut designed for Altrad/Belle concrete mixers, specifically the Superior 300 and Superior 350. Made from tough steel, it secures key rotating components such as shafts or hubs and helps maintain correct alignment under load. The M30 metric thread (30 mm) provides a secure clamp on the mating stud or bolt, while the slotted crown profile allows use with a split pin to resist loosening caused by vibration. As a Genuine Altrad/Belle part (MPN 946/99569), it matches the original specification for fit and performance, supporting reliable, safe operation in demanding site conditions. Use it as a direct replacement to restore integrity when the existing nut is worn, damaged, or missing.
