I've been looking at buying a set of Torx screwdrivers for taking small
things apart, the sort of screw that's 2mm across. But there seem to be two
notations out the

T4, T5, T6, etc
and
T0.5, T0.6, T1.0 etc (often they're quoted as T0.5x40, where I'm guessing
40 is the shaft length), such as these:
http://www.cricklewoodelectronics.co...cat=390&page=1

I understand the T4, T5 notation - I think the screws in my phone are
something like T4 or T5. But what does the other notation mean?
I'm guessing it might be something to do with the internal dimensions:
http://www.wihatools.com/torxspec.htm
in inches, but it still doesn't make sense. Perhaps T0.5=T5, T0.6=T6?

Thanks

Whilst I can't explain the size conventions, if you need a torx driver for
you phone, search on Fleabay. 353 hits just now for torx in the phone
category.

My guess is that your are right. Either that or the tools are more suitable
for watch repairs!

I have a small box of C.K Tools. The Torx parts are labeled TX 05, TX 06,
TX 07 and TX 08. ( i.e. use of leading zero)

I used them for taking a DEC phone apart.

I like these, and very keenly priced. Maplins do a very interesting range
of small and precision tools and the shops are always worth a browse round.
The dentist type probes and tweezers are handy too...

I've got the first one of those (7pce) and am very happy with it, fine for SE
phones but it doesn't have T4, just T5,6,7 +misc toys. I see the larger set
has T4 but it's 20quid.

The other day I needed a small Torx driver to undo a shroud around the
car's steering column - the right size one in my Machine Mart "Chesco"
set was a bit short to comfortably reach one screw. The only
"standalone" one I could get locally (a T20, very roughly 1/8"
'across') was a ½" drive, totally overkill for self-tappers into
polyurethane or whatever, so I just used it as a hand-held
'screwdriver' :-)

It cost a fiver, but I try to convince myself that it'll pay for
itself several times over... :-(

I preferred the data general nova (IIRC) myself.
There was a mod that required soldering a resistor (AIIRC) onto the

The memories are of the PDP-11 in assorted variants (11/70, 11/40,
11/34, 11/23, 11/73...) under RSX-11M and 11S. As well of memories of
reading the source code and becoming familar with the work of one D N

Done by IBM long before that...only it was snipping a wire.

Indeed. Nice touch about Bletchley Park. I really should have thought
about them when I discarded some reels of DECtape and software on
fanfold paper tape from a long-gone PDP-8 when moving house last
year.

I remember that OS/8 (the operating system for the PDP-8) had a
'programmer's joke' - on 4 July it would declare independence, and
respond to all commands with the command prompt and take no other
action. Even at the time I didn't think it was acceptable, but
perhaps I was just too serious...

Now those *really* were the days - the days of 12 bit words and 6 bit
bytes.

What's this - an OS for the PDP 8?

Load the 12 instructions via the keys, and then the (real) Bootstraps
and off you go - no need for an OS ;-)

My guess is that your are right. Either that or the tools are more

Oops, forgot I'd posted this thread.

I did a bit more digging and I think it's right. T5 seems to be defined as
0.5mm flat to flat internal dimensions of the hexagon. The wihatools link
above gives point to point dimensions which are greater. So I'm guessing
that T0.5 is in fact a Torx with 0.5mm hexagon dimensions, ie a T5.

I ended up ordering some from Ebay, which should be with me soon.
