Rated 5 out of 5 by from No rust streaks/sheared heads. I've used over 1500 of these to fix fence palings to their rails. Not one sheared off (I did drill a pilot and clearance hole), and I'll have no rusty streaks on the fence in a years time! Most pleased.

Rated 4 out of 5 by from Decent Screw A decent enough stainless screw, haven’t had a problem with the heads sheering off even with no pilot hole and an impact driver but only used them in softwood so far

Rated 5 out of 5 by from Great Product Ran out of the supplied stainless screws while fixing decking. These stainless ultra proved to be a perfect match. Not been down very long so cannot comment on durability, but great screws all round so far.

Rated 5 out of 5 by from Rust free screws Bought to replace the original screws fixing the drainpipe brackets that had rusted and stained the white brackets. Does the job perfectly.

If I predrill into 2.5mm steel will this screw work for me?

Asked by: Samuel87
Hello Samuel87, We would not recommend these screws for this use, unless you were fixing the steel to wood and the holes drilled had full clearance for the screws to pass through and grip the substrate. If we are fixing another material to the steel, please look instead at self-drilling or self-tapping screws. Thank you for using Q&A AS
