Keyed Double-Locking Quick-Release Pins
Use the key to unlock these pins, then press the button to release the spring-loaded retaining balls. Two-step locking prevents accidental removal. Use these pins in a hole as close to the diameter as possible, but not larger than the diameter at extended ball height. They are made of zinc yellow-chromate plated steel for good strength and some corrosion resistance. Breaking strength is measured as double shear, which is the force required to break a pin into three pieces.
