Merriway BH02863 (4 Pcs) Hex Bolt Sleeve Concrete Anchor, M8 x 10 x 100mm (5/16 inch x 4 inch) - Pack of 4 Pieces

I needed to mount a 9U Network Rack on my wall, 6.5ft above the floor. The Rack didn't come with wall mounting bolts, so I had to spend a few days researching how to mount this on a 6inch plastered block wall. Sadly all the examples I saw on Youtube were for mounting on wooden walls. Eventually I decided on Sleeve Anchors. Determining the appropriate anchor size was the next challenge. I needed one which will slide into the holes on the back of the rack with nuts wide enough to stay in place with the washer and long enough to extend beyond the hollow mid portion of a 6inch sandcrete block and penetrate the 2nd solid portion without bursting out on the other end of the wall. This bolt with its 4inch length was perfect for the job.The rack has been in position for 5 days now and is still as sturdy and solid as the first day I mounted it, even with the pressure I exert while installing and configuring network components inside the rack.

Used to fit a safe to a wall. Chunky bolt fit easily into a 10mm hole and tapped in with a hammer. Used insulating tape on the end so the nut wouldn't angle or work loose in the hole, partially filled with silicone sealant. Ratchett screwdriver and a 13mm socket as the access was tight.

Easy to use

Good Anchors we used 4x of these to anchor our Palram 6ftx5ft shed down which had anchor holes preset into the bottle of the frame in 4 corners.The sheds survived high winds and is still standing absolutely fine the issue i think with PVC sheds is people just put them up and then fill them with grear thinking it will be enough... they are wrong the wind will destroy the shed or slowly reduce the ridgidity of the frame until it falls apart.These work well for palram sheds!If i was being a little bit anal about it I'd have maybe preferred something longer but to be honest these are absolutely fine.

Ok, but struggled to get them to bite into the concrete and did not appear to be the best quality.

Did a grand job of anchoring a primrose 3.5mtr awning to our back wall, drill into brick not mortar, we had to slightly move one support bracket to avoid mortar line. Drilled smaller pilot holes on hammer, then opened them up on drill only, this ensures accurate sizes hole. Tightened with socket set, using 100mm length bolts.

Used to hang a heavy punchbag. Only used 3 and it holds my weight (80kg). Easy to install

Was meant to be 4, but only received 3. Not sure how many things use '3' bolts instead of 4 but will have to make do.
