48233RE: [bolger] Robertson (Square drive) Screws
- Feb 10, 2006Okay guys you got me. I guess I have to limit what I said to the situation
where one is re-using a screw, as I am wont to do. You can strip a long
Robertson screw on the second shot, whereas a similar Torx screw will go in
and out many times, no problem. Both Robertson and Torx screws are
available as stainless deck screws. You often get a free Torx bit in the
box of screws. It's at the bottom, I guess to prevent guys like me from
filching them. Yeah, I need to get a clutch drill soon. Seen any deals?
What's your model preference?

I have never had the experience of ever stripping out a Robertson
screw when driving it by hand in over 30 years of using them.
I highly recommend your method David, in using a driver with an
adjustable clutch, because it is possible if driving into hardwood,
with no pilot hole, to strip out the head - or twist it off - with a
Two other possible errors I have witnessed, is using a smaller size
bit to drive a size larger screw and using a driver bit that is worn
out so the edges are rounded. If the bit won't hold the screw by
itself it is either the wrong bit or it is worn out.
I have only seen torx screws that are meant for metal work. Was not
aware of them being available for use in woodwork. Not that I see
any advantage in them.
