Hi Alex

Bolt alignment trick using 1 1/2" x 1/4 x 20 in this case to quickly align the bolts going into the captive nuts, came about while I was having to constantly installing and removing panels to work on them and putting in all the pan head screws was killing my wrists. The bolt with a nut on it is so quick to install and remove run in by hand then just a quick twist on the nut with a wrench and it is tight.

Even if the panels are warped you can get a lot of them to come into line loose then tighten up the individual top nut. Once you are ready for finial assembly tight them all up, then replace them one at a time with the correct bolts.

Cheers Phil
