====== Stop using stainless fasteners on your Land Rover! ====== tl;dr: **"Stainless makes corrosion //worse// and is brittle"** ===== Reason #1 - Galvanic Corrosion ===== [[https://en.wikipedia.org/wiki/Galvanic_corrosion|Wikipedia explains why]] it's a bad idea, I put this page here basically just to try and help any passers-by. {{ http://fuddymuckers.co.uk/gallery/tech/galvanic_corrosion.gif }} Stainless pipe onto aluminium casting equals... {{ http://fuddymuckers.co.uk/gallery/s/500/127_CC2/IMG_3741.JPG }} ===== Reason #2 - Hardness is not Toughness ===== Stainless fasteners are very hard but they are very brittle, so they will snap under loads rather than stretch or bend. It is positively **dangerous** to use them for towing attachments, recovery points, wheel studs, brake callipers, steering, suspension... basically //anywhere// the manufacturer of your vehicle used a high-strength steel fastener. ===== Reason #3 - Galling ===== Stainless fasteners are way more prone to [[https://en.wikipedia.org/wiki/Galling|galling]] - binding up and self-welding - and when that happens you've now got an incredibly hard thing stuck somewhere. It's harder to drill a stainless fastener out, and if it's into a softer parent metal your drill bit is going to want to wander to the soft stuff.
