M12 x 1.5 Nylock Nut

M12 x 1.5mm nylock nut for Rush SR upright and suspension assembly. This zinc-plated steel nut features a nylon insert that provides vibration resistance and prevents loosening during racing.

The nylon insert grips the bolt threads, creating friction that resists loosening from vibration. This is critical for suspension and upright fasteners that experience constant load cycling during racing. The M12 x 1.5mm thread pitch is standard metric fine thread used throughout the Rush SR uprights and lower suspension mounting points.

Grade 10 hardness provides adequate strength for these applications. The zinc plating offers corrosion resistance. Nylock nuts lose their locking ability after repeated installation cycles - they should be replaced rather than reused after disassembly to ensure proper thread locking.

Sold individually. This is an OEM replacement part used in upright and suspension assembly.
