Hi Guys;
	Below is a message that I sent earlier to the RV-List. I decided that I
should send it along to this list as well. Though it is not directly related
to the rotary engine, many here might possibly be interested.

        Back in July I bought 500 Torx 100 degree, flat head, T-20 screws
from
MicroFastners. These were manufactured at the request of RV-listers. I'm
very happy with them, however tests by another list member showed that due
to the superior grip of the drive it was possible to over torque the screw
until the head snapped off. I don't feel this to be an issue as his same
tests showed them to also be of superior strength to the Phillips screws. A
little common sense when installing these, precludes any chance of over
torquing them.
        However, John Fleischer of Micro Fasteners has automatically sent
500
replacement screws with the smaller T-15 head. He has verified that it is
not possible to torque this smaller drive to failure. While I didn't feel
that it was necessary, I was quite pleased to find these in my mailbox this
afternoon. As before, I feel that they look real sharp and will make future
maintenance much easier (no more fussing with them #?!@??!!#! Phillips).
Since I have them I will use the new T-15's in all structural applications,
but will use the T-20's for non-structural applications.
        I'd just like to recommend Micro Fasteners to anybody who is
considering
upgrading their screws. Customer service like this deserves our support.
