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 withstand wet environments but will corrode when exposed to salt water and other chloride solutions.

316 stainless steel adapters are ideal in wet environments and will not corrode when exposed to salt water or harsh chemicals.

Aluminum adapters are about one third of the weight of steel adapters and resist corrosion in wet environments.

Adapters that meet ASTM specifications are made from or plated with materials that adhere to standards for chemical and physical properties, such as hardness.

Need to join two female-threaded parts, such as coupling nuts, with dissimilar inch thread sizes? Attach them to these adapters and tighten the exterior hex nut for a secure connection. You can also use these adapters to change the gender of a mating part from female to male, increase or decrease the thread size, or convert the threads from fine to coarse (and vice versa). The smaller adapters act as threaded standoffs, positioning and separating circuit boards and other components in assemblies. All of these adapters meet ASTM specifications, which means they’re made from or plated with materials that adhere to specific standards for chemical and physical properties, such as hardness.

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.
