Rated 4 out of 5Â by hbsbuilder Window fixings
Not much to say about these except that I have been using these to fix uPVC windows for some years and have always found them to do the job.

Don't remove the screw and insert the plug first.
You need to leave the screw inserted into the plug, tap it into the hole and then screw it tight. The end of the plug breaks loose and wedges itself tight as it's pulled back through the plug.
Rated 5 out of 5Â by MrMe Performed very well.
Used these at the weekend to fit some second hand UPVC french doors. Was a bit sceptical about how well they would work for the price ..... but I needn't of been they performed very well. Pulling the frame up against the packers as required without distorting the UPVC frame. So I would definately use these for any future UPVC window frame / door projects.
