Recessed-Button Super-Corrosion-Resistant
Locking Quick-Release Pins
Also known as M-style marine pins, these all-stainless steel pins stand up to corrosive environments and are passivated for added protection against corrosion and oxidation. A recessed button prevents accidental pin removal. For a more secure hold than standard quick-release pins, they lock in place until you push the button to release the spring-loaded retaining balls. Use them in a hole as close to the diameter as possible, but not larger than the diameter at extended ball height. The head has a hole to add a ring and lanyard (sold separately). Breaking strength is measured as double shear, which is the force required to break a pin into three pieces.
