Rated 5 out of 5 by from Great product Very easy to use and TX bit included. Bit never jumped out of the screw head. Used to secure loft boards to rafters. Found it easier to drill a 2mm pilot hole in the loft boards first. Definitely be using again.

Are these rust resistant?

I want to use these to put Hardibacker boards into wet-room areas and so I need rust resistant screws
Asked by: fonytinlay
Hello Fonytinlay, These screws will have a partial rust resistance however for a wet room you would be better looking to use stainless steel screws. Thank you for using Q&A. (LM).
