Alloy Steel Hollow-Lock Set Screws
Also known as jam set screws, these lock other screws in place, hold pins, and adjust spring tension. The hollow design allows you to inspect locked parts. A black-oxide finish provides corrosion resistance in dry environments. Length listed is the overall length.

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.
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.

Slotted Long-Nose Spring Plungers
Slotted on both ends for installation with a screwdriver. 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. Zinc-plated steel bodies resist corrosion in wet environments. 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.
