Description

M6-1.0 Serrated Flange Nut – Carburetor Stud Nut for GX200 & Clone Engines


This M6-1.0 serrated flange nut is designed to secure the carburetor, airbox, or aftermarket air filter adapter to the engine using the stock carburetor studs. The integrated serrated flange provides extra grip and helps prevent loosening from engine vibration, ensuring a tight and reliable seal at the carburetor mounting surface.


It holds the entire carburetor assembly in place, including the carburetor gaskets, phenolic insulator, and air intake components. Whether you're building a performance kart engine or maintaining a utility motor, these nuts are essential for a proper and safe carburetor installation.

Tighten to 60 in/lbs using a 10mm socket. Do not overtighten to avoid cracking the insulator or warping the carburetor body.
