Inch-to-Inch Male-Female Hex Thread Adapters
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.
Brass adapters resist corrosion in damp environments but will tarnish if exposed to salt or chemicals in the air or water.
