Over-sized Receiver/Trigger Pins

Forgot where I saw some at one point, but someone was running a set of over-sized receiver pins that had knurled rims setup to be removed with a wide flathead. Thought these were interesting and went to look into them more, but am unable to find anything that match what I saw. I'll try to remember where I saw a pic of them, but as of right now I can't remember for the life of me. I have Mesa Tactical pins on one of my 870's and wanted to used these over-sized ones on a sporting gun ever I need to pull apart the trigger housing from the receiver while I'm at a range (rare, but you never know.) Figured common tooling/finger accessible take down screws for the pins would be a nice change.

I think they are Remington 870 Anti-Walk Trigger Housing Pins

Close, but it doesn't have the knurled edges, plus the hardware you posted sits much righter to the receiver due to the button head on the screw.
