Securing fence posts upright in spike holders... 7mm too big or just drive it through the metal too? Regular 5mm don't look heavy duty enough for the long term?
Err I'm no expert on fencing but aren't the fence posts supposed to be tight to the walls of the spike holders? As far as I'm aware they're meant to be held in by friction, the bits of metal that are folded in where you're driving the timbalock are essentially there to increase friction.
Me neither... they are 100mm posts in what were sold as 100mm spikes and the interference folds are holding them but not jammed upright solid, there is some play. I've stuck some 5 x 30mm screws in as a temporary hold for now.
