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.
Even with a washer, the head of a straight bolt won't hold very well in concrete when you go trying to tighten it, it'll most likely start spinning and possibly even damage the concrete.
That’s true. I was thinking pull through but you’re right about spinning while tightening.
