Comment on ribbed plastic anchor in brick not holding -- what screw diameter do I need?
diyrebel@lemmy.dbzer0.com 6 days agoThat looks like it’s for a hollow wall. The middle looks like it’s meant to bend to a huge diameter. If that were inside a brick hole, wouldn’t it just make around 1mm of contact at the point where it bends?

You are right; my mistake! I meant to suggest a wedge type that theoretically functions similarly to the one you posted, using friction between the anchor and the pilot hole, but is made of metal. An important variable I didn’t notice if you mentioned is how much weight you intend to hang. This is what I was imagining:

Make sure to get one that includes a masonry drill bit to remove the hole diameter guess work!
I think some of us are struggling when we see you wanting to use a plastic anchor in masonry. It just doesn’t make sense unless the load will be very low.
Even if the anticipated load weight is low: if you hang, say, a shelf on a brick wall, people who place things on the shelf in the future are likely to assume you used a stronger anchor than plastic.
