Description
This is a steel/zinc air nut designed for GM cars, ideal for anyone restoring or maintaining original hardware who needs a reliable, corrosion-resistant fastener. Made of steel with a zinc finish, it offers the strength of steel with added protection against rust and everyday exposure. Sized M6 to match metric fittings commonly found on GM vehicles, this nut fits where OEM-style hardware is required for proper function and appearance. Use it when replacing worn, missing or damaged air nuts on brake, suspension or accessory fittings where the original specification calls for an M6 fastener. Its straightforward design makes it easy to swap in during routine maintenance, classic car restoration projects, or any job that calls for an authentic, durable replacement part from a trusted brand.
