Make Main Mfg. your source for 4 bolt flanges. Main products include SAE Code 61 (3000 Series)
and SAE Code 62 (6000 Series) 4-bolt flanges, SAE J1942 flanges, metric flanges including
ISO 6162, ISO 6164, buttweld, socket weld, stainless, and other flange adapters.
What are the advantages to a Main flange? Most Main products are manufactured from steel
bought from US sources to Main's own tighter quality specifications - not from countries
where the quality of the steel is questionable. Most are manufactured in the US, by Main, where we can control
the quality. We control the quality throughout, not just as a sales arm with a paper quality specification.
