I use these;



and these;



for the spanners in my tool box. First set are in one of the smaller draws for random spanners, second type is in one of the bigger draws for my ratchet spanners. It's actually a Halfords spanner rack, and it actually locks the spanners in it as opposed to them just sitting in it. So you have to twist them slightly to come out. Excellent as they don't all fly around when you're throwing the van over speedbumps

As for sockets, I just use the normal style socket rails I bought from Machine Mart YEARS ago;



Cut the rail down to desired length, slide on as many socket holders as you need and done. I have a socket rail for 3/8" drives, another for 1/4" drives, another for Torx sockets and another for reverse Torx. Not bothered to bolt em down or rivit them; just leave them in the drawer. If you have rubber matting and/or anti slide draw liners, they don't go anywhere. Also means it's easy to grab the entire rail if you need more than one socket on a job.....
