My pins have the detent ball also. Granted they release from pressure,mbut I cannot for the life of me see how that pin will put downward pressure on the setup I have. Its the ame pin besides a button releases the detent. On my hull piece,It simply has a hole drilled, with a lip at the top that is smaller od than the rest of the hole, the lip is about 1/16th, otherwise the pin is just floating below it. Maye rok are different I work with stainless all day long for my job. I'm not trying to argue. I appreciate the info. I fully support the idea you et what you pay for. In this case I got some self locking stainless pins.
