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.
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.

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.
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.

Hex-Drive Long-Nose Spring Plungers
Install with a hex key for more torque than slotted long-nose spring plungers. These spring plungers have a nose that is longer than ball-nose spring plungers to provide a large bearing surface and handle side loads.
Steel is strong and wear resistant. Black-oxide steel bodies resist corrosion in dry environments.
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.
Spring plungers with thread locker have a nylon 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.

Food Industry Vacuum Cups for Delicate Bags and Film
Attach these cups to threaded connections on your vacuum system to gently lift bags, plastic film, and other sanitary wrappings. They have an ultra-thin, flexible edge that presses against your item, forming a tight seal. The grooved stopper pad inside the cup keeps thin materials from wrinkling, without reducing suction. Made from FDA-compliant silicone, these cups are safe for direct contact with food. They're also bright blue, so they're easy to find and remove if they fall into your line. The aluminum fitting won't corrode from water and humidity.
Add levelers for vacuum cups to lift workpieces with varying heights.
Warning: Never use to lift people or items over people.
