Button Pins for Telescoping Tubing
Shown Installed
Single Button Straight Leg
Single Button Dog Leg
Double Button Straight Leg (Opposite Side)
Double Button Straight Leg (Same Side)
These pins use spring force to hold pieces of telescoping tubing together. Install them in the smaller tube, then slip the larger tube over the smaller tube until the button pops into a hole. Also known as snap buttons and tubing buttons.
Zinc-plated steel pins offer good strength and some corrosion resistance.
410 stainless steel pins resist wear as well as corrosion. They are magnetic.
301 stainless steel pins are the most corrosion resistant. They may be mildly magnetic.

Slotted Ball-Nose Spring Plungers
Without Thread Locker
With Thread Locker
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.

Press-Fit Ball-Nose Spring Plungers
Designed with a flange to keep the plunger from being pushed through a hole when the ball is depressed. These spring plungers have a tapered end and smooth body to make them easy to press into unthreaded holes in soft material such as wood, plastic, and aluminum. Drill a slightly smaller hole for a snug fit.
Steel is strong and wear resistant.
Stainless steel is chemical resistant and may be mildly magnetic.
Plastic is chemical resistant and lightweight; plastic noses are extra soft to minimize marring soft surfaces such as aluminum.
Brass is corrosion resistant in wet environments.
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.

Sealing Press-Fit Ball-Nose Spring Plungers
An O-ring in the flange creates a tight seal. Press these spring plungers into unthreaded holes in soft material such as wood, plastic, and aluminum. With a nose and body made from 18-8 stainless steel, they're chemical resistant and may be mildly magnetic. Drill a slightly smaller hole for a snug fit.
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 Ball-Nose Spring Plungers
With Thread Locker
Without Thread Locker
Install with a hex key for more torque than slotted ball-nose spring plungers. They have a ball nose that rolls to minimize wear and allow parts to move in and out of position. Made from 440C stainless steel, the nose is hard, wear resistant, and mildly chemical resistant.
Steel bodies are strong and wear resistant. They have a black-oxide finish to resist corrosion in dry environments.
18-8 stainless steel bodies are chemical resistant and may be mildly magnetic.
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.
