Don't know about better, but I've only used nylon type frame fixings in the past when I've had a masonary house. https://www.screwfix.com/p/timco-nylon-frame-fixings-8-0-x-100mm-100-pack/687kg Link to comment Share on other sites More sharing options...

I have just used these at 120mm to fix some 6x2 supports to a rendered lightweight block wall. I used a 7.5mm wood bit for the clearance holes, an 8mm masonry bit just to go through the render and then a 6mm for the length of the screw plus 10mm. You may need different if it is concrete block. If you are doing lots, make sure you have a few of the driver bits. I think they are TX30 and there is only 1 in the box. Link to comment Share on other sites More sharing options...
Conor Posted March 7, 2023 Share Posted March 7, 2023 We used those concrete screws, but 100mm long. You need a bit more depth. Also expanding foam the whole way round. Link to comment Share on other sites More sharing options...
