June 4, 20215 yr Hi All, im fitting a deck in my garden. I’m using hardwood beams (Azobe, 4.5 x 7cm). I have some stainless steel torx head fasteners. They just snap. Even with pre drilling. So I tried just a general purpose cross head screw - also snapped (and with pre-drilling)….. it seems to be when it gets towards the center of the beam (approx 1cm in). I also tried using my drill to drive the screws vs impact driver. Same result. so - I think I just have the wrong screws. Can anyone recommend some stainless steel screws that would work well here? thanks. Neil Edited June 4, 20215 yr by NeilScotland
June 4, 20215 yr Spax seem pretty good. https://www.spax.com/uk/projects/outdoor/decking/ If this is to screw the boards down, drill a full diameter hole through the board and a slightly smaller one into the joist the depth of screw embedment.
