I used one of these on a garden gate where the screw kept getting pulled out of the sandy cement wall. It was totally overkill for the job but it worked a treat and the gate bracket is still 100% solid 7 years later.
Been Looking for this for over a year! Now, how do we deal with a cinder block exterior wall with a plaster board lining it’s interior? It covers 2 walls of our smaller size bedroom and my son’s small bedroom. Need to hang heavy duty floating shelves for books and also, heavy paint cans! lol (I don’t like them outside because the constant cold temps and then super high summer temps tends to ruin them! 😂
Great tip about installing the bolts in the anchors onto the thing to be mounted and then inserting them into the drilled holes! I tried it by installing the anchors in the wall and then screwing the bolts in, but one of the bolts wouldn't grip and then it was a nightmare trying to get the anchor out of the wall again. All done thanks to this great video, thanks!
Just wanted to thank you for your video. This was what pointed me in the right direction. Where I live, most of my walls are ultra dense, reinforced concrete - kinda stuff used in UK high rises in the 60's. Anyways, I weight 130kgs and so bought a hefty pull up bar which is wall mounted with four M10 rawlbolts now. Never felt anything so solid. I then decided to get gymnastic rings and so SDS drilled into the ceiling, which is also this god-like super concrete (took ages) - installed M10 eyehook bolts and hung 200kg load carabiners and gym rings (straps and gym rings can hold 450kg each). I still was a bit concerned. Until I set one gym ring about 5 inches off the ground and put all my weight on it....for for 10 seconds I swung gently back and forth...all 130kgs of me. On ONE BOLT! Called RawlPlug UK to see if this was OK and Adrian laughed and said I could have 3 of me on one, and the carabiner and gym rings would give out before this single rawlbolt. If it wasn't for your video I would have never been able to get myself the gear I need to get in shape at home. So a huge thank you. I have subbed. :)
Thank you for the notes on how to pull these out. I have a few installed and I was worried on what to do in case I wish to take them out in the future.
Good video pal. For anyone looking to use these with only a standard masonry bit/hammer drill you can get away with using a bicycle pump and a needle tip (like you would use to pump up a football) to blow out the excess debris and dust. Messy but it certainly clears the cavity enough to allow a solid install.
In UAE here and living in Dubai from one of the old buildings.....Im planning to do this in my room to bolt a pull up bar. I need to drill 4 holes... 2 on each side. I think drilling is not an issue though not so sure if ill be hitting some cables or if its a solid block. Been checking videos on how to do this...
Do you use a drill bit that is 1mm larger than the bolt/anchor? I drilled using 12mm drill bit on the wall, and went in out a few times. But the 12mm bolt/anchor can't seem to go in. I abandoned it now as I did not want it stuck halfway and I have to use pliers to get it out or have to hammer it in.
I hope to be using these exact bolts to wall mount a display cabinet to an exterior wall in a small bedroom. Never used such a thing before but you make it look so easy, thanks!
Now a video in real time of you putting one back together when it comes apart. I bought 20 yesterday and 4 of them fell apart. Unfortunately I needed to use 18 and Screwfix had now closed. I spent more time putting two back together than I did fitting the rest of the shelves!
Thankyou sir I was fitting my pull up bars in wall and I only knew about plastic anchors These metal anchors came with the setup and i did not know how to use it. 👍🏼
Best video I have seen how to attach these. Clear and concise. A pearl between the rubbish out there. Keep making these video's. Thank you from Holland
I used the old 1/4" whit Rawl bolt on heavy hanging basket brackets some 40+ years ago and there still solid, I have removed and refitted them many times for painting also using the same bolts.
Followed this step by step when I hung my heavy punch bag! Went to B&Q bought all the wall bolts and very similar drill everything went great. Thank you for this video mate!! 🙏🏼 👍🏻👍🏻
@@chiefnkosi7705 Check the wall your using will be able to take the weight first mate. I hung mine from the wall inside the garage [normal house brick] and after a month the mortar between the bricks started to crack from the heavy weight and me punching fuck out of the bag!! Think I’m going to have to go with a free standing bracket now.. 😢😢
@@BigTastey my wall is made up of concrete blocks which filled with cement and the wall is plastered up with more cement so I can't see where mortars are. How can I check this?
This is great! Can these be used on a brick fireplace hearth (thin plaster over it ) I’m not sure how thick the brick is and if it classes as a single leaf wall
What an excellent video. I've been struggling trying to get mine to expand and I think I'll need to use a bit of resin to help but at least I finally understand how they work. Cheers!
this is just gold ....thanks for the in depth tutorial. hanged it on my wall for wall mounted pull up bar. now i have to pull it out again and shift it another place... this informative vid' helps putting it in and pulling it out ;) XD
Great video this is. I have a 12m rod that I need to fix to wall for a glass Juliet balcony but there is no bit for me to put the spanner on the end to tighten it’s just a full rod. Any suggestions on how I can tighten this up. Thanks.
Hello thank you for the idea. I bought a awning and these type of bolts came with it to hang on the wall. My wall is wood will then work on that or…. Thanks
Great video, thank you. I have a question…for stationary items I imagine this would be perfect but would this be suitable for heavy moving items such as a heavy duty boxing bag? My thoughts are, as the bag is moving the fixings might break away some on the wall material and so loosing its integrity. What do you think? Any suggestions on what I should use if not these? Cheers
I am spending my evening watching a video of a bloke balancing his entire body weight on the top of a bolt...and finding it weirdly enjoyable. Great videos
So I'm planning on fitting a weights rack to my garage wall & floor. It will not be used for anything too heavy.... Up to 100kg. My garage wall is also the gable end of my house and is mostly red brick, but the internal garage part is concrete blocks. I need something similar (this size may be overkill)..... Any recommendations?
Is there a better feeling than a plug or bolt tightening solid into a wall and it being level. It never gets old for me even for a simple wallplug and screw.
Mate, I've got no interest in DIY/joinery at all but these videos are mint. They're so relaxing. I've seen you dismantle two hotels, renovate two houses, inspect a couple of new builds and now demonstrate some mad claw anchor bolt things. Awesome.
Hi Andy. Excellent video. I tried installing some of these anchor bolts but the bolt is not catching the nut. I think my drilled hole may be deeper than the anchor bolt. Any solution or should I drill elsewhere a shorter hole. ?
i need to fit a steel bracket in my garage to lock a bike upto would i be able to add ready made cement in the hole to stop the screw been unscrewed again ?
Wonderful video! Finally understand how these work. Trying to add a couple of new ceiling ikea light fixtures and I got a similar wall expansion hook bolt.
What type of sleeve anchor would you use for attaching a motorycle anchor, specifically the hiplok wall anchor weighs less than 2kg i would say, to a brick wall. A reasonable heavy motorcycle chain will be going through the hiplok anchor. Would it be a drop in sleeve or expansion sleeve ?
Great thanks. Trying to hang a punchbag on a wall that's got plasterboard on top of brick. Bit of a nightmare but getting there. How tight do they go? I've got 3 in and seem to be able to tighten them and tighten them.....
Useful, thanks. Question: you mention in passing 'longer bolts', e.g. to fasten a batten to a wall? How to id such rawlbolts? What's the max thickness of bracket / batten for these please? When to choose a plug vs when to choose a bolt?
This is great. I needed to find out how to install my pull-up bar into a concrete wall and it uses these exact bolts. Super helpful! Now to buy a SDS drill. 😂
Should my external newbuild house wall with render over brick be strong enough to fix a wall mounted pull up bar using these fittings. I'm 85kg and the pull bar takes 6 bolts?
Hey! Thanks for that clear and instructive video! Could you help me with a specific problem? I want to pour a concrete slab - incorporating such wall bolts into it - rater than drilling holes later... Once the slab is solid - I want to remove the bolts from the housing (which should stay within the slab) and reinstate them to fasten my 'load' onto the slab. Do you think this could work? Thanks in advance!
Hi, I want to put shelving in a cupboard. The wall has just been plastered (skimmed) Behind the plaster is solid wall with bricks most likely behind this. I am inclined to mount wood (2 inch thick) and then place shelve on top. Would l need 8 inch bolts
great channel.one of the best with minimal fluff...Crucial to hoover out the hole.. I normally insert with bolt fully home otherwise there is a possibility of pushing the wedge out when tapping in...
If I use a 125mm x m8 bolt on a block wall to hold steel work sitting at 45 degrees. Will there be any issues using a longer bolt than say a 80mm bolt.
would this work the put a floor joist on in the loft to store a heavy item that the celing joist wouldnt take. it would only have to be about 3 joist to make a small platform
Hi there sorry to trouble you however I am looking for some advice. I am going to be building a window cannopy at the front of my house. And I have been instructed to fix some 6x2 timber to the house in order to take the weight of the cannopy and to fix it using resin and screwed rod. However as my house has wall cavities I can only insert the rods in 50mm. Should this be enough to hold the cannopy of is there any other fixing method I can use for example going through the cavity into the internal brickwork and use some other fixings?? Thanks
Would these also work in Breeze Block? If not, what would you recommend. I am wanting to install a gun safe which will be resting on the floor. Thanks.
Great guide, these wall bolts are impressively strong. Don't make the mistake I've done once when I've fixed these to plaster wall and overtightened them. Whole wall on the other side was cracked XD
Hi Andy, I have to agree with other comments made, I use concrete or “Lightning bolts” these days. I once tried to hang a heavy duty tv/satellite bracket on a new extension wall using rawl bolts. I drilled into the centre of the brick to find the bricks had frogs in them, the rawl bolts would not anchor and kept spinning. Ended up having to use chemical anchors instead after drilling many holes..... Rawl bolts are ok for drilling into concrete and dense concrete block, personally I wouldn’t use them on brickwork unless I was confident the bricks were solid. Thought I would share my experience, hope it helps!
Hi There. I am trying to hang an iron framed 30kg mirror in what I believe is brick work as it is a chimney breast. I was thinking of using atlas bolts as I need them to hook the mirror in the back. Have you got any advice on this please? Loved the vid.

Thanks so much for that recommendation. I'll defo give it a go.

I think drilling is not an issue though not so sure if ill be hitting some cables or if its a solid block. Been checking videos on how to do this...
I just saved me much grief with the tip on how to remove a wedge anchor. It worked easily.
You're the best, these came with a wall mounted punching bag that I got, wasn't sure how they worked and how to install them. Thank you for this video
Can you install it onto wood?
Perfect 👌very good explanation. Now I know how to use bolts. Thanks
