Multi-Fix Gold Flat Countersunk T30 Recess Concrete Screws 7.5 x 70mm Pk100
Used for fixing insulating boards to walls they are great. Drill straight through board into the wall, screw in, job done. Just need to choose the drill bit size carefully - on normal brick they work fine. Great time saving.

Quick and easy to use.
Brilliant for quick and easy fixings. Sometimes need to spin them out a couple of times. But work brilliant in combination with an impact driver.

easy screw, no plug needed
used the 180mm to screw 100mm fence posts to thick block wall. We are talking solid blocks here that needed the pilot hole to the correct depth, when done right, it was an easy screw all the way in. I tested on a breeze block and it screwed straight in without a pilot hole. On the solid block, no chance, where the pilot hole was not quite deep enough the blot head snapped off. no way to get these out easily, so use the right drill to the right depth. The head is a bit small and could do with being bigger or have a washer added. The torque needed for 180mm was too much for my DIY cordless drill, had to use electric drill, even then you could fry an egg on it after a few dozen screws. Also had to use the lower torque setting to reverse the screw out when needed. Star bit included in pack ;-D

super fast fixing
I used these to attach timber to brick and they worked really well. Super fast because you can drill blind holes and put the fixing straight in. Note some of these need some odd drill sizes. I didn't notice a 6.5mm masonry bit was spec'd, so I ended up grinding down an old 7mm SDS to size.
