Rated 5 out of 5 by from Screws are not just screws These are very good screws , having to work from underneath worktops etc you need the screws to start and the bits not to slip, these deliver both.

Rated 4 out of 5 by from Nice solid screw! A tough screw with a strong and sharp thread. Nice looking head and they weather well outside. As with all dome head screws you do need a particularly good fitting bit. These may be a touch more choosey than some but at this price it's something I can live with. Buy a good quality PZ2 bit and you can drive a whole box of these without so much as a hiccup. These are very hard screws. Be carefully with impact driver settings.

Rated 5 out of 5 by from just as expected Suddenly had the need for some domed screws, ordered them online and picked up a few mins later. Great screws, did the job perfectly, screwing metal to wood

Rated 5 out of 5 by from Good screws Hard to find decent dome head screws, but these worked a treat holding my windows in using lugs. I used these Rawlpugs with them. Rawlplug Rawl-4-All Wall Plugs Blue 6-8 x 50mm 50 Pack (28042)

Roundhead or countersunk

Am I confused or is this screw described as roundhead (flat bottomed head that won't sink in to wood) in the title and then double countersunk (angled bottom that aims to sink in) in the description - these are incompatible to my mind. ???
Asked by: JezHi
Hello JezHi, We can confirm that theses screws are Roundhead not countersunk. The specification will be amended shortly. Apologies for the confusion. Thank you for using Q&A. (LM).

Can these be used externally?

Asked by: Janicemc
Hello Janicemc. These screws are zinc plated and offer a degree of corrosion resistance but are not specifically for external use. Hope that helps. Thank you for using Q&A MH.

Would the 10ga x 2" be sufficient to hold a 25kg drop down screen to a wood battened wall?
