First of all let me say that I am so pumped that I was able to fit
four 12 foot by 2 foot Suntuf corrugated plastic panels in my
Westfalia I could just spit.  The sales guy at the lumber yard
couldn't believe it when I popped the trunk and loaded it in.
Neither could I.  The panels are for a shed I'm building, my first
(and potentially last) project depending on my success.

Can somebody tell me what tool I'm looking for?  The panels come with
these special screws, roofing screws that have a rubber washer
attached.  The head of the screw is hex shaped but instead of
inverted like an Allen key it is extroverted (ha, is that the right
word?) like a typical bolt.  I can screw them in by hand with a
socket but there must be some sort of attachment I could use to drill
it in.  What the heck do I ask the guy at the hardware store for?

Thanks as always
Jeff
