Ring-Grip Shoulder-Style Quick-Release Pins
A shoulder keeps a portion of these pins outside the hole and makes the ring easy to grab. Pins have a spring-loaded ball that pops out when the pin is pushed into a hole, and retracts when the pin is pulled out. For the best fit, the hole should be as close to the diameter as possible, but not larger than the diameter at extended ball height. Breaking strength is measured as single shear, which is the force required to break the pin into two pieces.
Zinc-plated steel pins have good strength and some corrosion resistance.
18-8 stainless steel pins offer a balance of strength and corrosion resistance. They may be mildly magnetic.
