I have lost so many bolts, sockets, allen wrenches and my lunch in my engine bay before. Thats why they sell those little mirrors and magnets in the auto parts stores. Dropping something always make my 20min job take hours.... AND IT DRIVES ME CRAZY!!!

 

Just turn the car upside down and shake it until the screw comes out, thats what I always do.

I forgot an open end wrench when installing my kmac kit last summer, it finally worked its way off the bolt I was tightening 4 miles down the road. That made a racket. I felt like an *** jogging back down the road to pick up the wrench.
