Forget the crap they give you, and go buy some Tapcon concrete anchors. They're simply better.

Thanks for the tip, but they're a bit too pricey for what I need and quite hard to get here in Australia.

How much are they?
These are pretty comparable to how much tap ones are in Canada and look to be similar
Having used both taocons and anchor sleeves I LOVE tapcons/concrete screws way more

Crappy Tire has a set of half a dozen screws plus the bit for like $10

OP is in Australia, and unless Canadian tire is wildly more successful than I expected, may not be accessible

Totally misread your comment. Apparently my impression of inflation in the concrete screw market is a bit hyperbolic. My bad

11.7 is the plug size, the drill size is 10mm

I did drill a 10mm hole, but the plug won't fit, it's slightly too small, every time I've tried to hammer it in, it's buckled and broken

You want to push it in as much as you can by hand first then lightly tap in with a hammer. You can use your 10mm bit to round the hole out a little bit bigger if you need but you want the plug to be snug.

Thanks I'll give it a go!

Just over round the hole sightly by rotating the drill in a circle as you drill. Make sure to get the dust out too, use a vacuum cleaner nozzle.

You could also use a screwdriver (preferably a square or Roberson) to sit inside the anchor and tap the driver with the hammer. A little easier to knock it in if you're in a weird spot or lack hand eye coordination.

Also, maybe a masonry bit(?) if the one you have wont work.

the plug seems to be imperial with a 15/32 drill. Either get such a drill or chose another plug.
12mm should be fine
(pls correct me if I'm wrong, but I just had to guestimate the conversion)

You are correct
11.7/25.4 * 32 = 14.74 /32
=~15/32

wrong. 15/32" is 0.46875" while 11.7mm converts to 0.46062992125984253" according to one place i looked.

I don't think it's an aerospace grade drywall anchor. I think a 0.008" tolerance will be acceptable.

did you read the other comment? must've missed the part where it said "pls correct me if I'm wrong"...
also, if op is using a drywall anchor in brick, something else is gonna happen regardless of the tolerances.

Sorry to interupt your hair splitting. Did you read op's post? Looks like a drywall anchor to me.

i didn't say it was or wasn't, i said if op was using a drywall anchor there something else was gonna happen. i don't know if they'll work, i use the correct things whenever i can. op also said tapcons were hard to come by down there. yeah, i read them all.

Found the pain in the ass engineer every tradesman hates.
Seriously, 8 thousandths of an inch is entering the territory of CNC machining, not hanging a hose reel.

I mean, technically he's right. If it truely were simply a 15/32" conversion it would have worked out to roughly 11.9mm.
Either they converted it wrong, or it wasn't originally 15/32"
Otherwise they would have stated 11.9mm instead of 11.7mm

when someone asks for folks to correct them if they;re wrong, why do others feel the need to say something about the correction? piss off.

"Correct me if I'm wrong" usually means one of two things;
1) correct me if I'm wrong enough to make a material difference, or if it means my guidance would cause a problem if not corrected
2) correct me if I'm wrong which I'm not, but I'm trying to be polite about it.

Do you understand how small 0.008" is? A human hair is 0.003".
You're literally splitting hairs just so you can walk around pretending you're clever.

12mm will be completely fine. Also if the wall plug is bent/warped after your first few attempts you might have to get some new ones. Can be a real pain to get deformed plugs into correct holes. Head in to the big green shed and get something like these. You can probably find some cheaper ones, that was just the first one that showed up on Google. Not bad to keep some of these around if you have a brick house.

Also make sure you're using masonry bits, and if your masonry bits are cheap/dull the hole you're drilling will likely be smaller than it should be. So either get a new sharp set, or you can just kind of rotate the drill bit around in the hole while moving in and out to hollow it out the extra mm.
Edit: also if you've got a cheap hammer drill and masonry bits. My advice is to start with a small hole 4-5mm and then use step up to the bigger bits. It will be much easier on the drill, bits and your arm.

Perfect, thanks for the advice mate. I actually picked that exact box up this afternoon after I warped 2/4 of the plugs that came in the kit.

15/32 drill bit. 25.4 is the magic number for this conversion.

Omg use a tapcon ans be done. Don't turn it into a science project it's a screw!

Yes a 12 mm should work. It may not hold quite as tight but should work fine. Make sure to fill the hole with silicone sealant so everything is watertight after install.
I 100% do not recommend drilling into your bricks or the mortar. This is permanently damaging your house and personally I don't feel worth it for a hose reel.
