Owlett Ulti-Mate woodscrews, very easy to drive, use a Pozi-Square drive bit (supplied) but will take a standard Pozi as well, and seem to make a good strong fixing. Highly resistand to cam-out and will happily take the punishment from an impact driver too. Think they're also available at Jewsons as an own-branded product. Bit more expensive than standard screws but worth the extra IMHO

Ulti-mate screws are great, until you start using large ones. The bit size doesn't change, and I've snapped several while driving 5x90mm screws.

Good point - does the bit size change with KTX screws in the larger sizes?
