Got some elderly-person-handrails on my new-old house banged into the front
door and several places inside which seem to have been driven in by some
sort of massively powered leccy screwdriver. No amount of leaning on
screwdriver, different lenghts, girths of screwdriver seem to shift the
buggers. If worst comes to worst the wall ones can be forced out somehow,
even if it involves drilling straight through the metal, then just plaster
over the mess. The big prob is a handle with large screws in the wood just
beside the front door, where I want to minimise damage.. It just won't
budge. Bought really hefty quality screwdrivers - it just won't move. Don't
want to try any more with force as its just going to trash the screwheads.
They're posi drive type heads.
Apply some penetrating oil and allow it to soak in.
Try applying some heat by inserting an old screw driver and applying
heat to the shank.
Try tightening the screws a little first, before unscrewing.
Try an impact screw driver, or even give an ordinary screwdriver a good
thumb on the head whilst trying to turn it.
Seconded - I've had final success using these two methods in sequence on
screws I'd given up on. For both manouvers (the initial slight clockwise
twist, and the final backing out move) keep *lots* of pressure on the
driver to stop it twisting out of the damn Pozi head; if you round it
off you'll have a simply horrible time getting the screw out.
I've also resorted to putting a pair of molegrips onto the head once a
stubborngitscrew is a little way out, to allow one-handed further removal
with no more contradictions between keeping the driver pressed inwards to
stop it slipping, while actually wanting the screw to come outwards...
Good luck - Stefek
I can recommend this route! I had a weird fitting on an old radiator I
needed to change the tails on but I couldn't get it to budge. It had 2
protrusions inside the fitting which went inside the radiator. On advice
from Dad, I bought as large a slotted screwdriver as I could find (10mm tip
but wider slightly further back) with a hex nut fitting on the handle. I
heated the radiator fitting/end as much as I could and then stuck this
screwdriver in. The widest part of it jammed up against the 2 lugs and with
a spanner on the handle I could get it to move slowly and I got the fitting
Highly recommended these hex fittings - never had use of them before (or
really thought about why they were there) but very useful.
Aha! - the quality screwdriver I mentioned earlier has the hex bit at the
top, and showing my cmplete DIY ignorance had failed to work out what it was
for. If that don't work I'll try the impact screwdriver idea.

Impact screwdriver from your local car repair emporium and a good
sized lump hammer. The shock they produce is far less damaging to
the screw head than sustained force. If you have an electric
soldering iron you can also try holding that on the screw head for 10
minutes. Try tightening for a couple of blows and then un
In general, a brace and bit (if you can find a pozidriv bit). The
combination of pressure with a quick flick of the handle works wonders. I
used to use it to shift 100 year old 4" x 14 screws that nothing else would
IME long screws of the modern variety often can't be driven home fully more
than once with a cordless, which suggests the heads wear just enough to
prevent a decent fit.
