Review on Socket Organizer Tray Set for Toolboxes - 6PCS Red SAE & Black Metric Socket Storage Trays, Deep and Shadow Socket Holders for 1/4-Inch, 3/8-Inch & 1/2-Inch Drive by Johnny Burns

I thought I was lucky, unlike everyone else who said their 11mm 3/8" sockets didn't fit. no Both the shallow and deep 11mm 3/8 pins prevented the socket from being fully installed. It gets stuck on a small ledge designed for stability. Yes, I turned the bushings upside down. These are Craftsman 11mm hex sockets. Not sure if it matters compared to other brands because 11mm should be 11mm anyway. Luckily the kit is cheap enough that I can cut the 11mm holders with a utility knife with no regrets. Maybe a 12 point head would be better? As another reviewer said, it looks like the 11mm is the same size as the 12mm. You have been warned!
