Hi,

Anyone know where I can get a Torx T20 TR bit/screwdriver which has
the center tamper resistant/security hole?

The cheapest I've seen it online is for just under £6 (of which nearly
£4 is p&p) at:

http://www.toolspot.co.uk/product/8p...roof-torx-bits

but I'ld prefer to get it in a local shop if I can (B & Q Online don't
have any entries for "Torx").

Thanks!

In my experience, you can often snap off the little tamper resistant 'tit' -
and then use a standard torx screwdriver.
