I’ve been using Spax screws and Fischer Duopower plugs pretty much exclusively for about a decade, and have had no issues whatsoever. This was for paying customers, who would certainly have mentioned it if their cabinetry was falling off the walls.Sorry thought the thread had been deleted. I was advised not to use Spax type screw because when using rawl plugs they ruin them when driving in.
Not used that type but only use Fischer nylon plugs, mainly UX and SX and both the rimmed version that sits flush and un rimmed that can be pushed into the hole. I can still remember the days of the old brown fluffy plugs, I bet Peter started out with these and also having to use wooden plugs in bad holes and the plastic coloured plugs that were pretty useless, really amazing that we have progressed so far in so many other areas yet simple wall plugs took so much longer to reach maturity!Fischer Duopower plugs
