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.

Aluminum pins are one-third the weight of steel pins. They resist corrosion and are nonmagnetic.
