I am about to install a security screen door which will be attached
to the house with 8 included 4-inch color-matched one-way screws.
Obviously, I need to get it right the first time. According to the
oh-so-simple instructions, I just need to drill 3/16-inch holes,
then use a flat blade screwdriver to insert the screws.

How do the pros do this? Is there a drill bit for one-way screws?
I also had the idea to first install the door using 2-inch hex-head
lag screws, then remove them one by one and replace with the one-way
screws.

Any suggestions would be very much appreciated.

You would drill smaller pilot holes and then screw in the screws by
hand. If you use a power drill, your hand will probably slip and the
bit will damage the door.

An impact driver is the only way to fly.


there's a magnetic bit holder with an outer sleeve that slides over the
screw head,keeping the straight bit centered in the screw slot.
I have one I found in the road while bicycling.
It looked like an ordinary magnetic bit extension,but then I discovered the
sliding outer sleeve.

I don't know who makes them.
