"Being an electrician I need products that I can rely on. I have used these nails a few times now for first fixing houses as I have found that they are one of the only nails available that once driven into breeze block walls to hold down capping won't work loose. Straight shaft nails can easily fall out. To get these back out you would need a bar or a puller to remove."
"Used these on hangers when building my deck as I had noticed a review from another buyer saying how good they were. I found them excellent and as he said 'try getting them out'...they certainly grip."
"I use these to secure cable capping to brickwork prior to plastering. The nails generally hold well into the lime mortar - where they fail it's generally the Victorian mortar rather than the nails which are are fault!
I've marked them down slightly because of the number of nails (10-20%!) which have "tags" on the point due to incomplete manufacturing, making them useless. However, even allowing for this, they're still a good product at a good price."
