hi. Thank you for video. I have a uPVC frame and a heavy entrance door. the upvc thick is about 3 - 4 mm and the screw come out. the frame has a thin metal bar inside but the scres are coming out. Please give me an idea about what to fit inside of hols in upvc frame to screw in for a heavy door: resin with drill bits ? what exactly ? many thanks !

I am not finding the vinyl window screw on the GRK website, is this discontinued?

GRK doesn’t make good screws. I have had nothing but problems with them breaking. I would think twice about getting any GPK. I have no confidence in their products.
