Interesting. Basically if it needs a nut it's a bolt. But if it goes in(be it drilling or an existing threaded hole) it's a screw.
I've never heard anyone use 'square headed screw' when referring to putting a bolt into an existing threaded hole via socket/wrench.
And that typically the shape(no point, square head, tools used) define the name.
- TheLarch 10y agoI've never heard anyone call a lag bolt a screw, and yet they are pointed and never mated to nuts.
- tesseract 10y agoI see "lag screw" nearly exclusively in formal engineering or industrial settings. "Lag bolt" seems more like a hardware-store colloquialism.
- Shog9 10y agoWas just at Ace Hardware picking up carriage bolts yesterday... They were right next to the prominently-labelled lag screws. I'll probably keep calling them lag bolts too.
