    I ordered these, they were threaded to the end I ordered 50mm length (says 45mm is threaded but the whole 50mm was threaded)

    My gantry mounting plate thickness is 20mm but I recess into the aluminium 5mm so the bolts go 35mm into the extrusion it seems rock solid far far more so than when I assembled it with corners. I have enough corners to do it all without bolts and drilling but it just seemed to make sense to me that a big M12 35mm into the end is going to be stronger than a T nut and £35 drilling cost seemed ok given the hassle it would have been for me to line them up correctly. Having at least 1 (2 is better) corners with T nuts is very useful when you want to assemble it.
