Rated 5 out of 5 by Strong screw Very strong screw, can apply huge pressure to head and no distortion of slots, great buy 11 Jun 2016
Rated 5 out of 5 by •••••••••••• Very nice screws, hold stuff together very well. I also used them to hang things to a wall in conjunction with rawlplugs and they didn't fall off. They didn't snap when I used an impact driver either. Bit pricey mind. 17 May 2016
Rated 5 out of 5 by First class First time used these screws as others have stated not the cheapest but drive in well a pleasure to use. 13 May 2016
Rated 4 out of 5 by Feather board fixing Excellent screws for fixing fencing feather board to cross beams without splitting wood. Easy to screw in without the need to drill pilot holes. 30 Apr 2016
