So I just purchased a 2017 F-250 and took it in to get a sprayed in bed liner. Went to pick it up and was told to bring it back in a week and have the bed bolts re-torqued. Took it back and found out that Ford had changed the bed bolts and now a "E" socket is required to remove and replace the bolts. Ford doesn't even have the special sockets out yet. Called MAC tools and wouldn't ya know, they have them. It's an E24 Plus socket. If you contact MAC tools, the part number is VIMVSP8EP24. It's about $12
