Clever ways to put washer, lock washer, and nut on bed bolts

[hairdog]

I am at the installation phase of my 1966 C20 bed wood and rails. I was wondering if any of you folks have figured out a clever way to fit the washer, lock washer, and nut onto the bolt. My fingers must be fat because I have trouble fitting them and the two washers up into the channel, then holding them up there until I can also get the nut into the channel and get it threaded onto the bolt.

I have toyed with the idea of super-gluing the nut and washers together but there probably is a better way.
