M8 Anchor Fixings 4 Pack

Bought to mount heavy floating TV stand on new build dot and dab wall. Absolutely rock solid. They're not what I would call DIY fixings, you need to be able to drill a hole accurately since as some others have said, once in place, these are as good as a tapped hole in the wall. Make sure you drill the 16mm hole for the plug deep enough and vacuum out the debris. Some have complained there are no threads in the plug for the sleeve - there aren't meant to be otherwise it would be a slack fit. It takes some welly to wind the sleeve in. The hex heads aren't machined very well so use the ball end of an allen key wobbled around to open them up and make sure you've got a secure connection before winding them in. After fitting 10 of these, my shoulder was aching. You'll need at least a long 8mm allen key and plenty of strength or as I used, an 8mm hex head with 1/2" ratchet which makes life easier. Resist the urge to get a nut gun or similar on them, you need to feel if anything is binding otherwise you'll wreck the hole. Wind the sleeve in until its sat just into the top of the plug and then the most satisfying part is the final fix where the machine screw fits snuggly into the sleeve securing your item to the wall. Totally recommend but absolutely not for beginners. Well worth the money. Perfect for dot and dab walls, the sleeve bridges the gap perfectly. (Edit: These are heavy duty fixings for heavy duty applications. For hanging medium weight items such as radiators on dot and dab walls, make life easier for yourself and look at COREFIX fixings which are perfectly adequate for that sort of weight.)

This product is brilliant, extremely strong, and well designed. It guarantees that something heavy will stay in place provided that the wall is strong enough and deep enough. The drill size is 16 mm (yes I could not believe I had to drill such a large hole, but its design makes this necessary. One little challenge is that you have to be very precise because there's almost no flexibility once the plug is in the wall, compared to a classic nylon plug where being off by half a millimetre is OK.

"Ha, good luck with that" - My Dad's response when I told him my plan to secure a bracket to hold a 25kg punch bag to a breeze block wall. In yer face Dad!! Well after a bit of a struggle with the installation, 3 of these fixings have given me an absolutely rock solid mounting. For the installation you will need - A 16mm drill bit (doesn't need to be a masonry bit for breeze block) and drill of course - A 8mm hex key, or much better a 8mm hex attachment for a socket/ratchet set (the long handle and ratchet very useful as it takes a lot of torque to get the metal bolt in) - Hammer - Large phillips screwdriver. A bit of detail on my installation in case it's useful: - The idea is to drill a deep 16mm hole, insert the plastic sleeve with a tap from the hammer, screw the metal bolt in (needs a 8mm hex key), and then finally attach your item using the screw - Screwing the metal bolt in is really hard work! I'd advise getting a 8mm hex attachment to a socket/ratchet. I was using practically all my 80kg weight to do the last few turns. - I watched a youtube video where someone was installing a smaller m6 fixing and used a 18v cordless drill and 8mm hex attachment to screw the metal bolt in. I decided to make my own attachment and cut the end off a 8mm hex key using a dremel multitool, and inserted into my 18c makita cordless drill. Well, it didn't have nearly enough torque to get the bolt in, not even close, so ended up doing it by hand with a hex key, and about 10min of really hard work and grunting per fixing! (High up placement of the holes near a wall and ceiling made it a bit awkward.) I wish I had an 8mm hex attachment for my ratchet! - I had an issue with one of my fixings where the metal bolt just wouldn't screw into the plastic sleeve. Was just spinning around. Had a look inside and there was some protruding plastic inside the sleeve stopping the bolt going all the way in, so I briefly inserted a 6mm drill just to get rid of the excess plastic, and that solved the problem - I also didn't drill one of the holes quite deep enough, so ended up cutting the protruding plastic with a stanley knife. All in all, installation was a bit of a pain, and there were no instructions with the items, so I was tempted to knock off one star. The end result though is a very solid fixing in breeze block, so it was well worth it. Hope that's helpful to others.

As other reviewers have said, once fitted, these are very strong, but require care in installation. At the risk of repeating other reviews, here are my key points - 1 Measure carefuly and be accurate in your drilling. I was fitting a safe and the mounting holes on the safe fortunately were slightly larger than the bolts, allowing a margin of error, but it was still a bit of a struggle to get securing bolts aligned with fixings. Drilling a small guide hole worth doing before using the big drill bit. 2 My walls were of dry lined, lightweight breeze block (Thermolite ?) and the plastic inserts were easy to push in and tap home with a hammer. Screwing in the metal inserts took some effort. This was made a great deal easier by using a ratchet socket wrench with a hex key, and I lubricated the threads with soap before inserting them. I took it easy without trying to rush and it all went in fine. All in all, it took me about 30 - 40 mins. Once fitted, all seemed as steady as a rock, and won't come off in a hurry ! Only one criticism, the fixings were delivers "bare" with no instructions or even information on drill size. Had to ascertain 18mm drill needed from the reviews, hence 4 stars.

Had to fit a tall safe to a concrete block wall. Worked perfectly, rock solid result. Im happy, inspection officer was happy. For reference my wall is the older more solid concrete block type, as opposed to the more modern 'aerated' type.

Bought to fit large, heavy TV bracket (for large heavy TV) to dot and dab plasterboard over insulation block (quite soft). Bracket came with M8 bolts. I used the Rigifix instead. Excellent solution. Ony of my best ever DIY jobs because everything went as planned! Only worry was drilling the holes in the right place. Measure twice and drill once. I used a 16mm flat wood drill bit which went through the soft wall material easily - masonary bit and heavy duty drill not needed in my case (but clearly you need to know what you're going into). Had read other reviews warning about difficulty inserting the metal sleeves. I turned them in by hand slowly using a socket set and allen key bit. You need some leaverage, but they all went in very smoothly. No slippage, really neat job. Highly recommended for modern houses with soft walls of similar construction.

I bought these to fix a bracket to an external brick wall for a heavy punch bag (the fixings that originally came with the bag weren't up to the job). After using these bad boys, the bracket is now rock solid on the wall - Nothing is pulling it down! Be warned that you need A LOT of strength to screw the steel insert into the plastic outer rawl plugs - it took me ages to get them in, and several rest-breaks to relieve my arms (and at one point I really did wonder if they'd go all the way in), but with a few drops of washing-up liquid on the steel to help act as lubricant, combined with a lot of strength, I finally got them in ...and boy, was it worth it! I've also used the smaller M6 versions of these to fix flat-screen TVs to walls. I would highly recommend them ...you just need to be prepared to persevere to get those steel inserts into the plastic plugs, but once they're in the fixing is absolutely solid!

My go to fixings for dot and dab plasterboard. I have tried many similar fixings with mixed results but now I keep a stash of these in stock, as I know they work and are very secure. They aren't cheap but neither is a Miele cooker hood!
