While I was reassembling my intake after fixing a leak and installing new knock sensors, a friend who was over said he had never thought of a trick I used while bolting down the intake and injector rails.
I always get helpful tips on the list so I snapped a couple pics and thought I would pass it along.
I always use a long pick to drop the washers and nuts on the studs to prevent dropping them.
Then keeping the pic on the stud while I use my finger to then turn the nut. Sorry the pics suck but you get the idea.

 

Very good idea.

I use a magnet on the extension to get the same results. I like your idea better.

 

Somebody showed me that years ago. Good that you are passing it along.
