I've always seen Posi 1, 2 & 3 bits at Wickes/B&Q etc, but never any Pozi 4. Do they exist?
I only ask because, having shredded another of those Rawlplug screw in frame fixings, I'd like to find one. You know, the 100mm long, 10mm dia mediumweight ones that clearly have a head suited to something larger than a Pozi 3.
Having just looked on Rawlplug's website, they really do require a Posi 4. Anyone seen one?
