These all-stainless steel pins, also known as M-Type Marine Pins, withstand corrosive environments and are passivated for better protection against oxidation and corrosion. The recessed button keeps the pin from accidentally falling off. For a more secure hold than standard quick-release pins, these pins lock in place until you press the button to release the spring-retained ball. Use them in holes as close to the diameter as possible, but not larger than the diameter at the height of the extended ball. The head has a hole for easy attachment of optional chain or lanyard. Breaking strength is measured as the double shear, that is, the force required to split a pin into three pieces.
The Recessed Button Handle Pin made by Runsom helps prevent accidental pin removal.
