How to screw in anything without jamming the threads

I learned this from the Adam Carolla Car Podcast


some poor guy jammed and stripped the threads of his oil drain plug. Here is how to screw in anything (works great for lightbulbs) without jamming the threads.

"Righty Tighty - Lefty Loosey"
First think "Righty Tighty - Lefty Loosey" so you remember how screws and bolts work.

Turn backworks in hole first "Lefty Loosey"
Don't use a tool at first, just with your hand make your first turn *backwards*. You are spinning the screw or nut backwards first, to make sure the threads are mating straight. You will feel the screw or nut rise up then "pop" back down - that is the exact place where the threads will mate perfectly. Now you are ready to screw.

Now screw forwards - hand tight first
Now that you found the place for the screws to mate by spinning backwards, now turn forwards "Righty Tighty" just hand tight. Don't use any tools. Turn it hand tight

Now use tool for final tightening
Finally, use a tool for the final tightening, and lock the screw or nut in place with the final 1/4 turn.
