These positive locking quick release pins have a wide range of uses in fastening, locating, and alignment applications. The pins will not release until the button on the handle is depressed. Once the button is depressed, the balls retract into the shank allowing the pin to be inserted or removed into or out of a hole. 

Dome handle and other quick release pins are available in a variety of lengths and diameters with shanks made from 17-4 stainless steel, 300 series stainless steel, or 4130 alloy steel. Inch and metric measures are both offered.
