Rated 5 out of 5Â by Jimmybat MAN Screw!
These fixings are some of the best i've ever used. I have used these for a number of constructional timber projects, and have found them to be accurate, easy driving, and super-strong.
No need to drill pilot holes, and the partially threaded shank means they pull up nicely.
Not cheap - but you can see why.
Can't comment on the corrosion resistance, as the fixings outdoors have only been out one year, but no sign of rust yet....
Rated 4 out of 5Â by Tiredofguessingnicknames Great Grip
Was a little worried these wouldn't be substantial enough for deck joists, but seem to grip well.
Rated 5 out of 5Â by pwiles1968 Use instead of Tmber Drive
I bought these and some timber drive screws the ones with the bolt head for a project, and these were easily as good, they drive in really smoothly, I used pilot holes but they will drive in without them.
The Torx or TStar head mens no slippage too, expensive but great quality.
Rated 3 out of 5Â by John221 Very useful
A handful of these bad boys was all it took to tighten up a loose staircase from the underside. The long length, large, load speading head, and high strength make them excellent (but not cheap) when nothing else will do.
