Tempted to replenish my screw stocks with one of the cases featuring in
Screwfix's clearout 'sale'.
Can someone enlighten me as to the differences in real terms - not in
the terms that appear in the Screwfix ads - between:
Turbo Ultra
TurboGold
Gold
Goldscrew Plus
Quicksilver
and then suggest which to buy (and why!)
I'm looking to buy the biggest offering in a case. I don't want
something requiring an esoteric driver and will only be doing what I
call crude timber fixing - no high class cabinet work, just a step up
from nailing bits of timber together or to walls and brackets to the
same (both interior and exterior).
TIA

OK, I'll bite...
The Screwfix ad's are pretty clear about the differences between their
different types and what they're best used for (see "Choosing the right
screw" on page 6 of the Winter 2006 catalogue).
The only comment I would make is that having a "razor sharp tip" is not
necessarily a good thing and if you're screwing (or nailing for that
matter) close to an edge, you should consider turning the screw (nail)
upside down and tapping the head with a hammer to blunt it slightly to
avoid splitting the wood (unless of course you drilled a pilot hole ;-).
Twin threads screw in faster than single threads, but single threads are
notionally better for soft woods/chipboard/mdf.
Turbo Ultra are class A2 stainless steel (aka 304 stainless) which is
not as rust-resistant as class A4 (aka 316). A4/316 should be used for
marine work by preference.
Otherwise all variants are made from zinc-plated mild steel. The
technical term is "zinc plated and passivated" The passivation can be
either clear or yellow/gold coloured (note, there's no actual gold
involved). Screwfix have specified that their single thread screws are
yellow-passivated and their twin thread screws are clear-passivated, so
you can tell the difference by the colour if you have a mixed bag.
Finally, the silver twin threads are sized in Imperial gauges and the
gold single threads are sized in Metric - which may be a consideration
if you grew up with 1 1/2" No 8's as being the one screw you don't want
to run out of!.
Goldscrews are the cheapest and will work with all wood-types.

Actually, on closer inspection, the Quicksilver ones are on average
slightly cheaper than the Goldscrews if you compare like-for-nearly-like
(well spotted Gerry).
I suspect Screwfix may be about to phase out some lines and go over to
the Spax equivalent.
For basic work like that you can use anything with a coarse thread,
doesnt matter a damn what it is. PB screws are sometimes cheaper.

Better idea. Don't buy any of them.
A far better choice is to go for Torx screws. They don't have the
same tendency for cam out with the screwdriver that Pozidriv screws do.
The drivers are readily available just as easily as PZ as well - not at
all esoteric.

for the screws
Order code 305087 for a set of screwdrivers, 310082 or 900384 for bits,
then 510030 for a case to put them in.
Far better deal, easier to use and better performance than screwfix's
offerings.

Must admit, Pozi isn't as good as it's cracked up to be. Shame square
socket screws have never caught on in this country - despite a firm
somewhere pushing them quite hard.

Pay no attention to that man behind the curtain.
I use the Quicksilver for general purpose use and when fixing via wall
plugs. The Turbo Gold are useful for those jobs where you need to screw
near an edge or in awkward spaces or use large screws without a pilot.

You can get them for use with collated screwdrivers.
They tolerate the grab and release without stopping effect quite well.
The old adage still holds true, 'use a nail, if it splits, you should have
used a screw'

And I stopped looking after that! It's a _little_ bit more than I
really want to pay. I'm only a bodgit-at-home bloke. But thanks Andy.
I do however agree with you about cam out problems with PZ screws. I
have a very old PZ driver (with a wooden handle) that grips PZ screws
well enough for me to hold the screw on the driver at any angle. I've
never found a bit for a cordless electric driver that offers that
performance ;-(
