5/30/2009
Hello Matt, Thanks for your tool tip. Here is another tip that you can
distribute to the RV people if you will (I am not on their lists).
Where ever possible abandon those abominable Phillips drive machine screws.
Instead use Torx (six lobe) drive machine screws.
Every builder who has done this has thanked me profusely for the suggestion.
Torx drive inserts are readily available and with an electric cordless screw
driver are very quick and effective -- vastly superior to Phillips drive.
You can obtain Torx drive screws in a variety of sizes from Microfasteners.
See here:

(Note that these flat head screws have a true aviation use 100 degree
countersink angle, not the common hardware store 82 degree countersink
angle)

PS: Thanks again Matt for making the Matronics lists available to us -- they
are of great value.
