Ring-Grip Quick-Release Pins
![](/prerenderstable/mvPRE/contents/gfx/imagecache/952/95255a268c1-b02-digital-master1560544276-p9@halfx_637039639135957978.png?ver=imagenotfound)
The smooth ring handle on these pins won't catch on parts. A spring-loaded, nonlocking retaining ball pops out to hold pins in place. The hole should be as close to the diameter as possible, but not larger than the diameter at extended ball height. The ends are chamfered for easy insertion. Breaking strength is measured as single shear, which is the force required to break the pin into two pieces. Also known as faspins.
Brass pins are corrosion resistant, nonmagnetic, and electrically conductive.

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.
Stainless steel is chemical resistant and may be mildly magnetic.
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.

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.
Brass is corrosion resistant in wet environments; brass noses are soft to minimize marring.
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.
