Change thread sizes or types, such as fine to coarse threads, on parts without changing gender. These adapters can also be used as standoffs to position components in assemblies and to create space between parts. They have an external hex, so you can tighten them with a wrench.

At about a third of the weight of steel adapters, aluminum adapters are the lightest we offer. They resist corrosion in wet environments.

Adapters that meet NAS standards are made to specific dimensions and are finished with an extra layer of rust protection. Aluminum adapters that meet NAS standards have a yellow-chromate plating, and stainless steel adapters have been passivated.
