Merriway BH02862 (4 Pcs) Hex Bolt Sleeve Concrete Anchor, M8 x 10 x 80mm (5/16 inch x 3.1/8 inch) - Pack of 4 Pieces

Drilled some holes into a concrete slab - slotted these in and tightened them up and they are solid as a rock very easy to use and install.One thing to use these your will need to drill a whole into concrete. So you will need a hammer or SDS drill if your going to use these.

Anchor bolts are right for the job

Good quality and competitively priced expansion bolts.

Great bit of kit, easy to use and holding up well. Used a 10mm drill bit to make the initial hole and then took some light knocking in to get the bolt into the hole. Once tightened these aren't going anywhere!

Hit and miss as to whether they work or not...When the work they are very sturdy

Always sceptical about buying things like this on the internet, but they were needed and I didn't have the chance to travel to visit a hardware shop.Bought 2 lots, and all 8 did what they were meant to do, which in this case was ground anchor a post holder into concrete.They worked a treat.

Used for a project with concrete. Did the job and all seems strong

Not used yet, but as advertised and well price. Will give five stars once used
