10 x 75mm M8 Concrete Self Tapping Anchor, Bolt/Screw, with a hex Head, Fixes to Brick, Stone, Masonry & Marble etc...

I was a bit dubious of the claims these can be screwed directly into concrete with no plugs but was pleasantly surprised. Used them to attach post supports to a concrete floor. They tightened well and held fast. Only issue was that I had to add a washer to fully tighten as the screw thread ended a couple of millimetres short of the head.

Firm fix first time

Great VFM and holds really well (I used these to give additional security to a fence post I am now using as a gate post.Make sure you put them into brickwork, but no more than half a brick away from the edge of a wall as it splits the brick of its too close to the edge.

I'm building a large shed that uses one wall of the house as one side of it so I'm attaching 45x95x2400 timber to the brickwork.Into the wood I drilled a 10mm hole and used a 25mm spade bit to just go deep enough to make it flush with M10x25 penny washers from toolstation.For the bricks used an 8mm masonry bit and a ratchet to tighten the anchor bolts in. Really easy to do and the bolts are TIGHT! That timber isn't going anywhere and I've got a really solid attachment to the house.

As described, drill hole to correct size (about 2 mm down from screw size),Insert and tighten, I used for attaching a decking joist to my bricked garage wall,Garage and decking are still standing strong

Not as good as pricier brands but OK as long as concrete not too hard

Recently replaced a garden gate and needed to replace the wooden posts bolted to the house wall and a brick garden wall holding the gate up. Previous posts were in with regular screws and rawl plugs which had worked their way loose over the years. Decided to replace them with these bolts (m8 100mm size) after seeing a bunch of people using them online to do similar jobs. Have never used self tapping brickwork fasteners so slightly skeptical. Drilled an 8mm hole and then used a regular socket set to slowly screw these in, applying a bit of pressure as I went. They all went straight in, no problems and they are TIGHT.....great fasteners that i'll definitely use for projects in the future. Recommended.

Fixed some batons to a wall - drilled the recommended size hole and screwed the bolts in with a socket wrench. Solid.
