Masonry Mount Black 9mm Pack of 100
Great for fixing cable runs
Used loads of these in brick, cinder and concrete blocks. Agree with other reviewers that drilled hole size needs to be accurate and at 8mm in hard brick or concrete they can be a little tight, careful use of hammer usually gets them in. Only broke heads off a few in several hundreds used, molding design could be improved if the stem between vanes and head was strengthened by lengthwise buttresses to give a '+' cross section. Otherwise a great product for well supported tidy cable runs especially when used for heavier 6mm and 10mm T&E cables.

They seem to work
I've only used a few of these so far but they seem to be working. An 8mm drill gives a hole that is slightly too tight. Tapping the plugs in with a hammer breaks off some of the ribs, but enough are left to hold the plugs tight. I had to remove one and I couldn't shift it, so I had to drill it out.

Does the job
Be good if you stocked a smaller size as well, and stated the drill bit size, as 9mm is the one size that you cannot buy an SDS drill and the 8mm is too tight and 10mm seems to be a little loose? Maybe it was the material I was drilling into?!

We used to use banding to secure items to the underside of the floor beams. Slowly, everyone has been won over to these fixings. Cost effective both in price and labour saving. Have used them on site in the middle of Winter, no problems, as long as you use the correct size drill. We find that an 8mm SDS is ideal.
