Gate hanging: Expanding bolts?

Question

Friends,It is a long time since I requested assistance but I have hung a 3foot wooden gate on a brick wall using those 8mm plastic plugs intowhich you hammer a threaded screw like pin.The plugs are now pulling out of the wall and I would like to replacethem with expanding bolts or anchors but I keep getting confused overthe lenth of bolt required.The post is 3 inches (I prefer Imperial, my age, you know!), thereforewhat length of bolt do I need to purchase?I am expecting to drill out the old holes to 10mm and there isclearance between the gate and the post to accomodate both nuts and alarge washer to spread the load.Regards, Peter.

I'd use threaded masonry bolts the post to a depth of 1.5" (large enough diameter for a socket & washer) & use the M8 x 100.  All you do is drill an 8mm hole deep enough (you could re use the existing holes), drive in with socket.No expansion to crack the bricks, very strong fix.  Easier to pull a sailor off your sister etc......

Dunno. For my stock of Multi-monti's I usually check the core diameter with a vernier caliper and use that to pick the drill (across the carbide insert. Can't read the size on the shank on most of my masonry drills any more.

Trying to select "by eye" I usually pick a drill too large. If you get the right drill, and clear the dust out properly afterwards, it's a "firm" but not a very difficult job with a socket set (usually use a brace tool or a ratchet handle). Get it right and you can remove them and then re-use the hole.
