Which type of bolt is best for securing a metal box to a wall to prevent it being pulled away: Screw Bolt or Anchor Bolt?

3Depends on what the wall is made of, where you're anchoring to it, what forces the box is going to put on the fastener... We can't give a good answer unless you give us more details about what you're trying to do. – keshlam Dec 20 '14 at 0:36

So it's going into a brick wall. The box itself, one half is open and the other has a drawer. So I just don't want it to be pulled off. – userMod2 Dec 20 '14 at 0:40

2How much weight, how much torque when the drawer is extended...? My instinctive response is that the anchor bolt, in an appropriately sized hole, will hold better but a malliable anchor insert used with the screw bolt (or an ordinary sheet-metal screw) might hold as well or better. I used anchors to support the lumber rack, but that was decided "by guess and by golly". – keshlam Dec 20 '14 at 0:47

If you use the screw bolt with a hammer drill to pre-tap, I'd recommend pushing a small amount of PL into the hole first to both help fill gaps and provide better holding power. – David Hoelzer Dec 20 '14 at 2:37

2Those anchor bolts are for concrete or stone and require a precisely-sized hole, in which case they are very strong. Red clay bricks are too soft and the anchors will pull out. What kind of brick? – Tom Robinson Dec 21 '14 at 7:11
I'm old school: I still use lags and shields. They "never" pull out when installed properly.

I'd tend to agree; I've never put 'em in, but they sure as hell don't like coming out. The fastener shaft usually snaps first before it will dislodge the wedges. – Mazura Mar 24 '15 at 22:32
