Hi Everyone! I have some existing terracing in the garden using (two tier) untreated oak sleepers. I am about to extend the terracing and have bought some galvanised steel stakes to drive into the ground and attach to the sleepers. I spent some time researching the correct screws to use and stainless steel seemed the way to go (to avoid corrosion & staining). But I struggled to find the right size in time, so ended up purchasing some zinc plated coach screws in the end... https://www.screwfix.com/p/turbocoach-coach-screws-yellow-zinc-plated-6-x-70mm-100-pack/22717 It states they're suitable for hardwood, but just wanted to double check before committing? Any advice would be much appreciated.
Thanks! It looks that way. Carbon steel with zinc plating. Was thinking the high carbon content might cause them to shear if the sleepers move over time. But I've over engineered the number of fixing stakes, so hopefully that will help.
