Join threads with small diameters to large or course threads to fine with these inch-sized adapters. Use them to position components in an assembly, or to create space between parts. An external hex lets you tighten or loosen them with a wrench.

18-8 stainless steel adapters can be used in wet environments, but chemicals or salt water will cause staining and rust spots.

For areas exposed to salt water or chemicals, 316 stainless steel adapters are the best choice. Only harsh chemicals, such as hydrochloric acid, will cause them to corrode.

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

Change inch threads to metric with these adapters, or swap metric threads for inch. An external hex lets you tighten or loosen them with a wrench. You can also use them to increase or reduce your thread size, or to create space between parts in an assembly. They meet ASTM specifications, which means the materials they are made from or plated with adhere to specific 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.

One side inch, one side metric, and a hex in the middle—these handy fasteners connect two female-threaded parts, such as coupling nuts, adapting from inch threads to metric. Tighten with a standard wrench.

You can also use these adapters to change the gender of a mating part or increase or decrease its thread size. The small sizes work 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.

Install these spring plungers with a screwdriver—they're slotted on one or both ends. The ball nose rolls to minimize wear and allow parts to move in and out of position.

Steel is strong and wear resistant.

440C stainless steel is hard, wear resistant, and mildly chemical resistant.

316 stainless steel is more corrosion resistant than 440C and 18-8 stainless steel and can be used in saltwater environments.

18-8 stainless steel is chemical resistant.

Brass is corrosion resistant in wet environments; brass noses are soft to minimize marring.

Plastic is chemical resistant and lightweight; nylon noses are extra soft to minimize marring soft surfaces such as aluminum.

Spring plungers without thread locker are for use in soft material such as aluminum, in extreme temperatures, and on parts requiring frequent assembly and removal.

Spring plungers with thread locker have a locking element that adds friction to resist loosening.

Extended nose force is the force required to begin to depress the nose. Compressed nose force is the force required to depress the nose flush with the body. When using a plunger as a detent or stop, a lighter nose force with a shallower hole releases more easily, while a heavier force with a deeper hole holds more securely.

Install with a hex key for more torque than slotted ball-nose spring plungers. They have a ball nose that rolls to minimize wear and allow parts to move in and out of position. Made from 440C stainless steel, the nose is hard, wear resistant, and mildly chemical resistant.

Steel bodies are strong and wear resistant. They have a black-oxide finish to resist corrosion in dry environments.

18-8 stainless steel bodies are chemical resistant and may be mildly magnetic.
