## Questions & Answers

**Q: What is the weight loading for 4 screws (as I have seen two conflicting ratings, 100kg and 250kg)? Thanks**
A: Depends on what is being drilled into.  It's 100kg per 4 screws into concrete blocks, 73kg for aerated/lightweight blocks, and 250kg for steel-reinforced fixings

**Q: Once installed, can we unscrew for wall painting, then screw it back in?**
A: Loosening and re-screwing any fixing will cause degradation of the hold especially where plasterboard is concerned. So it is always best to Just lift the TV off the bracket and paint around the bracket and carefully through any holes.

**Q: What size is the actual screw? I understand the plug requires 10mm as does the sheath, but what is the screws diametre?**
A: Thank you for your interest in CoreFix. I can confirm that CoreFix original are supplied with 5.0 x100mm single thread screws with a 10mm screw head. Allowing for a fixture depth of 10mm. I hope this help you make an informed decision. Kind regards, Lucy

**Q: Can I use the red ones on lightweight blocks if I've ran out of the blue ones?**
A: Hi Ian, thanks for the question. Yes, the products are interchangeable within masonry and aircrete/thermolite blockworks. Please adhere to the advised safe working loads of 100Kg (Corefix Ordinal - Red) and 73Kg (Corefix Air - Blue) over four fixings to ensure a secure fixing. Kind Regards, Andy

### ⭐⭐⭐⭐ Great fixings but for light blocks drill a smaller hole than 10mm
*by L***M on 17 October 2023*

Pretty good fixings but make a practice fixing first. I found if you are fixing into light/medium blocks then the recommended drill size of 10mm is too big and the screws don't bite into the plug enough to expand it in the hole sufficiently (the screw threads tore out when tightening with just two fingers on the screwdriver). This is because the actual screws are relatively thin in diameter /thread depth (which is necessary in order to fit through the steel collar). I recommend using a 9mm drill bit for the full depth (100mm), then open out to 10mm for the front (approx 50mm) portion. Also drill without hammer action if you have light blocks (hammer action tends to make the drill bit walk a little and you get a larger hole). (I didn't have a 9mm masonry bit so I drilled 7mm using proper masonry bit with hammer action, then just used a old 9mm hss steel bit without hammer action - this will cut through like butter). Then knock the red plugs home using a long screw (don't hammer the end of the plug or it will fold over). Using this technique gave a really strong fixing. I used 6 of these to mount a 49" TV on an articulated bracket that pulls out and rotates. I also used 8 of these fixings to mount a 75" TV (flush to the wall though; it's too heavy for an articulated bracket). Overl, spend 5 minutes perfecting your installation technique and you won't be disappointed. I've bought a load more of these for my toolbox (wish I'd just bought a large box rather them buying 4 or 6 at a time).
