Applications

These 3M - Marson threaded inserts are highly versatile for both automotive and industrial environments. In automotive repair and customization, they are utilized for securing components in vehicle bodies, panels, engine compartments, chassis, and interior assemblies, including seat mountings, heat shields, and exhaust system brackets. For industrial use, they are ideal for creating sturdy attachment points in machinery, equipment housings, and structural components, particularly where original threads are stripped, new fastening points are required, or when working with soft or thin base materials that benefit from increased clamping pressure.
