Inch-to-Inch Female Hex Thread Adapters
Connect two differently sized male-threaded parts, such as threaded rods, and tighten with a standard wrench. The threads on these adapters have various sizes and spacing, so you can increase or decrease thread size or adapt from coarse to fine threading. You can also use them to change the gender of a connection from male to female. Small adapters can work as threaded standoffs, which position and separate circuit boards and other components in assemblies.
18-8 stainless steel adapters resist corrosion caused by water. They're good for wet and damp environments but will corrode when exposed to salt water and other chloride solutions.
316 stainless steel adapters have the best corrosion resistance. They stand up to wet environments, just like 18-8 stainless steel adapters, but unlike 18-8 stainless steel adapters, they resist corrosion caused by salt water and harsh chemicals.
At about a third of the weight of steel adapters, aluminum adapters are the lightest we offer. They resist corrosion in wet environments.

Low-Strength Steel Coupling Nuts
Also known as extension nuts, use these to connect and extend threaded rods. They're about half the strength of medium-strength steel coupling nuts for use in light duty fastening applications.
Zinc-plated steel coupling nuts resist corrosion in wet environments.

Stainless Steel Extra-Long Coupling Nuts
These coupling nuts have good chemical resistance. Also known as sleeve nuts, they're at least twice the length of standard coupling nuts to provide more room to connect and extend long lengths of threaded rods.

Steel High Hex Nuts
With a height that is 50% taller than standard hex nuts, these nuts provide a larger gripping area for installation with a wrench.
