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

Inch-to-Metric Female Hex Thread Adapters
Adapt threaded rods from inch to metric. These adapters connect two male-threaded fasteners, so you can change the gender of a mating part or increase or decrease its thread size. The hex-shaped body fits into the head of a standard wrench. Small adapters can also be used as standoffs, positioning and separating 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.
