Rated 5 out of 5 by from Great product Excellent screws at a good value price point. Used 200 of these to secure 2” timber to sleepers. Drove in very well with an impact driver with no duff screws or breakages.

Rated 5 out of 5 by from Reliable, quality screws Reliable screws, as described and store well in the box for the occasional DIYers who don't need to go through 100 screws quickly. Found the screw-heads sturdy, although haven't used them in my impact driver so will update this once have had the chance.

Rated 3 out of 5 by from Not cheap, and half of the pack bent! The shorter version of these screws (4.0 x 40) are great, but these 60mm ones are mostly bent (where the threaded part meets the smooth part of the shank) making using an impact driver with them a pain. Won't be buying again.
