It seems they work better in wood.
What is the best screw for using with wall plugs?
Are the Fisher Power-Fast or the Spax better for that purpose?
Thanks,
Antonio

Plan old fashioned slightly tapered wood screws, IME.

They work exceptionally well in wood, but I've found they cut up plugs
quite badly.

Quicksilver.

Dunno, but they are mucho expensive.
All I carry on the van is Turbogold for wood & Quicksilver for plugs.
And they are Rawlplug 'Uno' which are the mutts nutts.

Which is what they are designed for really...

Quicksilver twinthreads seem to work well (and are much cheaper than TG
as well)

Not tried the Fisher, but the Spax are similar to TG in design, so may
suffer the same problem.

The problem with Quicksilver screws is that the head wears out very
easily.
That is a mayor problem, especially when unscrewing that old screw that
has been fastened several times

I've not experienced that in 5 years of doing this for a living.

Then don't reuse screws. Or use a decent bit - pozi & phillips are
incompatible.

I agree with Tim - an old fashioned tapered screw causes the plug to
open up and expand into the hole. A modern screw tends to merely cut
a thread into the plug without opening it up. We have gone backwards!
Personally I have found that QS are one of the better screws for
resisting head wear. However, you *must* use a bit that fits them well.
SF own brand bits (Erbauer) seem to work well, as do Wiha and Vira.
Ordinary steel bits are not really up to it - especially with the more
powerful drills and impact drivers.

The moral of the story is don't reuse screws - or at least not more than
once. Its a false economy. On the rare ocations that a head does get
damaged mid way through driving, I will take the screw out and use
another rather than persist in trying to drive a damaged one.
The old tapered screws cause a tapered expansion of the plug - with the
taper widest at the shallowest point. They also cut a thread in the
plug, but by their nature tend to destroy it again in the process of
driving the screw further into the hole. I would say it is more
important to drill the right sized clearance hole with parallel thread
screws, but personally I have never had any problem getting a decent
fixing with them into plugs.
(modern brown plugs tend to open up at the deep end more than along the
full length of the shank - anyway, and so are well suited to modern screws)
A Quicksilver in a Uno plug - easier to pull a sailor off your sister
than pull that out.
