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 2 out of 5 by from Does not match picture Purchased these based on the photo, which makes it look like the thread goes all the way up to the head. Unfortunately there is at least 10mm of plain metal between the screw head + where the thread starts. Misleading photo, please update it screwfix.

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?
