This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.
This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?
Just post some stuff and don't spam.
J Bolts for concrete don't have a head on them. The bent part is embedded into the concrete and would never be turned. Forming a hex head would be a wasted extra production cost.
