M8 Rigifix Heavy Duty Wall Anchor - 1 Pack

These are excellent fixings for fixing very heavy loads to 'dot and dab' plasterboard walls. When you put in these fixings, it's immediately clear they'll carry a very heavy weight.I used them to put a 22kg 65" TV on the wall using a Von Haus bracket  VonHaus 37-70" Double Arm Tilt & Swivel TV Wall Mount Bracket with Cable Management System for LED, LCD, 3D, Curved, Plasma, Flat Screen Televisions - Super Strong 45kg Weight Capacity .They come in 3 pieces: a big plastic plug for the wall, a steel sleeve that you screw into the plug and then the bolts you use to fix your item to the wall plug / sleeve.You need a good quality 12mm drill bit for the plug, you then screw the steel sleeve into the plug using an Allen key - these are very stiff so as others have said, using an Allen key drill bit in an electric drill is your best bet. DeWalt 32 Piece XR Professional Magnetic Screwdriver Bit Accessory Set However, there is a problem. The bolts that are supplied are absolutely terrible - very soft Phillips heads which quickly get stripped when applying pressure to the screw (and yes, I was careful to use the right size screwdriver). Really, for jobs where the bolts need a lot of force you need one with a hex head so I abandoned the bolts supplied and replaced them with 25mm M6 bolts with hex heads which are widely available from builders' merchants - these worked brilliantly.I used my superb Bahco mini socket set  Bahco SL25 Socket Set 25 Piece 1/4 Inch Drive  to tighten the bolts (this was also useful for tightening the nuts used to adjust the tilt angle of the bracket - there is a mini spanner included with the mount but it's not great).

This is the most sturdy fixing I've ever used. It's ideal for fixing heavy items to a dry-lined "dot & dab" wall. I used them to fix a bracket to the wall that is designed to hang 9 guitars. Obviously, it didn't want to risk it falling!You will need a drill bit of the correct size. For the M6 fixings I bought, a 12mm drill bit is needed. I used a masonry bit, but with no hammer action, as I was going into breeze block (or cinder block). I followed advice I found elsewhere by drilling a smaller hole first, before using the 12mm bit to widen it. The plastic "rawl plug" part should then fit snugly in the hole.Once the plastic part is in place, the larger metal part is then screwed all the way in with an Allen key. This then transfers all of the weight to the underlying breeze blocks rather than the relatively flimsy plasterboard. It takes quite a bit of effort, but you will then appreciate just how solid the fixings are.Finally the smaller bolt is screwed into the larger metal part to secure whatever you want to hang.One slight criticism is that one of the 4 smaller bolts in my pack was slightly rusty. This wouldn't affect the function of the fixing, but might look unsightly if it could be seen. I only needed to use 3 of the fixings anyway

very strong and easy to use

Used these to put on a wall bracket for a 65 inch tv and a 55 inch tv as did not feel like the plugs supplied would have supported the tvs weight.They are really good. Have had my tvs on the walls for years on the wall and no problem..

These fixings arrived promptly as expected. My plan was to use these fixings in an existing brick but wall to hold up a shelf. It's a huge slab of timber so I thought these would be ideal to bear the weight. The plastic sleeve glides in to the drill hole with no issue. But here's the where the product fails..... The metal sleeve is supposed to be screwed into the plastic sleeve via the M6 bolts enclosed. These bolts may as well be made of butter! The screw heads are way too soft and have been rounded off with minimal effort. This has resulted in me have to purchase a pack of extra M6 bolts with a hexagonal bolt head. Avoid the cross head screw fixings at all cost. Save yourself an additional trip to Screwfix to buy the suitable bolts.

I needed to attach a range of Ikea kitchen units to a plastered Thermalite block wall in a new utility room. Initially I was going to use threaded rods set into Fischer resin, but thought I'd give these Rigifix bolts a try instead.I marked the hole positions, drilled a small pilot hole, then enlarged it to 12mm. A tap with a hammer seated the Rigifix rawlplug, then I tried using a hex bit in an 18v drill to screw in the long bolt. This only sank the bolts about half way as my drill didn't have sufficient torque, so I put the hex bit into a socket and used a ratchet handle to tighten the bolts up by hand. The final step was to hold my Ikea suspension rail in place and use the Rigifix M6 bolts to fix it to the wall.The result was solid as a rock. I hung a 2m tall kitchen unit (50kg) on a section of rail that was held up by three Rigifix anchors and I was able to stand in the unit (adding about 70kg) with no issues at all.The cost of the fixings can soon add up if you need a lot of them but it's a comparatively small price to pay for peace of mind when you consider the expense you could incur if your television or kitchen units were to fall off the wall as a result of being improperly secured.

Never seen anything like these.I drilled 10mm pilot holes into dab and dot wall into the block behind using a sharp and lockable bit into the chuck. Then I used a 12mm masonry bit on the normal drill setting to the correct depth. Hammered the plastic plugs firmly into the holes and the used an Alan key to get the threaded cylinder into them. I needed to used the end of a spanner to get more leaverege on them, because some where very tight.
