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.

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.

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.

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.
