Knob-Style Retractable Spring Plungers
 Knurled Knob |  With Thread Locker |
 Without Thread Locker |
Retract the nose by pulling the knob. These spring plungers have a long nose that provides a large bearing surface to handle side loads.
Knurled knob spring plungers provide a slip-resistant surface for controlled adjustment.
Steel is strong and wear resistant. Zinc-plated steel bodies resist corrosion in wet environments.
18-8 stainless steel is chemical resistant.
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 patch 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.

Slotted Ball-Nose Spring Plungers
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.
18-8 stainless steel is chemical resistant.
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.

Long-Nose Spring Plungers
Install from the nose end without depressing the nose using a driver (sold separately). With a nose that is longer than a ball-nose, these provide a large bearing surface to handle side loads.
Steel is strong and wear resistant. Black-oxide steel bodies resist corrosion in dry environments.
18-8 stainless steel is chemical resistant.
Plastic is chemical resistant and lightweight; acetal 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.
