Screwing into concrete
 

Have heard about screws that you drill a pilot hole and screw directly into
a concrete floor - no raw plug so ideal for fixing floor boarding, skirting
and the like.

But I can not find them in either Toolstation or screwfix in less that 75mm
lengths - all described as for frame fixing.

I only want to fix 22mm floorboards to a concrete floor so am looking for
something about 45mm or so.

Any suggestions?

You can use ordinary screws/plugs if you tap the plug through the hole
with the screw before tightening it. Depending on the plug, you may have
to cut the lip off

ICBW but I'd have thought that you needed them to go into the concrete
by more than 23mm in order to hold firmly.

Same here - thinking about the springiness of floorboards. Even if hard down
on a solid surface, the give in the wood and repeated compression will have
an effect.
Screws are only a friction fit (in the Antarctic, the buildings are bolted
together as the thermal cycling loosens screws).
Some of the reviews mention that the 'thread' in concrete won't survive many
removals/replacements, so I'd go for a longer screw for more insertion - er,
what's the subject? - for strength in the thread as well.

how many removal/replaces will screws holding battens under flooring have to endure?....

Probably only screw in once, but did like the ability to easily remove the
skirting boards.

But point taken about length - I'll go with the longer ones recommended by
someone else at screwfix (unless I find similar in toolstation?).

Screwfix search is utterly bizarre. I wanted a Drayton TRV and
lockshield today (as I was doing an direct replacement). Searched for
TRVs and saw none - only other makes. Then remembered that I had one in
my basket - from there I could see my local branch had 8 in stock.

I get the impression that Screwfix website is now maintained by the
jokers who do the B&Q website. Who else could keep making it worse and
worse?

Think you must've broken something, just tried it and that combo in
white TRV4 was on the top row with chrome TRV4 and RT212 lower down. Try
clearing cookies?

Search item site:diy.com in your favourite search engine to get round

OK - more exactly, I typed TRV and saw "trv and lockshield" offered,
which I selected. That took me he

http://www.screwfix.com/search.do?fh...and+lockshield

It appears they have some under "lockshield" others under "l/s" - I
sort-of made the assumption that their offered search term would cover
the ground. It didn't.

Wood moves, how many fixings are you intending to put in?

One more than they'll withstand, of course.
