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.

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.
