Pretty new with everything about drilling stuff into the wall, so forgive me.
I tried to use a recommended wall anchor (click the link for more info), and unfortunately, about halfway through, the anchor couldn't go any further.
I took the anchor out and saw that it faced some kind of white plastic material(?) behind the drywall.
I assume that this is a plastic pipe where some cable goes through it, not quite sure tho.
Any idea what it is?
Can you please recommend to me what should I do next time to avoid such cases next time (besides the apparent avoid drill vertically above lights/wall plugs).
Will a stub finder (with wire/whatever detector) can alert and assist me?
I am attaching the following pictures so you can better understand my case.
Thank you

    @jsotola to present a better view of what's around the hole and where's the closest wall plug is to see if maybe I hit a pipe of electric wires or something like that. Commented Oct 16, 2019 at 19:30

Is your wall made of cake? That first picture looks like cake.

But seriously, look at the plastic anchor your tried to put in that hole and compare it to another one. I think you will find that the used one is broken. What happened is you screwed that anchor in to a stud, and it broke, leaving plastic behind.

Drywall anchors are used to hang things on drywall without studs behind them. If you need to hang something on a wall where there is a stud, just use a screw in to the stud. The screws that come with the anchors will probably work just fine. Or try installing another anchor an inch to the left or right, if the positioning is not that critical.

To prevent this in the future, you just need a little experience to feel the difference between hitting a stud and not hitting a stud with that type of anchor. Alternatively, use a stud finder to locate the studs first.

Or if you pre-drilled the hole, you just need a bit of experience to feel the difference between drilling in to a stud vs. just the drywall. Also, wood chips coming out of the hole while drilling is a clear sign that you hit a stud.

An appropriate screw for a light object such as your mirror would be a wood screw that penetrates the stud by at least 3/4 of an inch, plus 3/8 or 1/2 an inch for the drywall, plus whatever mounting length you need. 1 1/2 inch wood screws are probably suitable for your project. Depending on the size of the anchor you have, the screws that came with it are probably that length already.

  • Definitely a cake :P You were right, the anchor indeed was broken, and the white part is the anchor itself. Couldn't get it outside, but hopefully, it indeed hit a stud. I am about to mount an IKEA mirror that weighs 22 lb. I have no idea what's the limit that normal screws that hold while being held on a stud - any purpose? Also, what would you recommend to use next time to prevent such mistakes? Thanks for the reply btw Commented Oct 16, 2019 at 4:31

  • I always use this type of drywall anchor: amazon.com/Ansoon-Self-Drilling-Drywall-Anchors-Together/dp/… I get them from the big box, store, though. Check the weight limits on the packages. The larger ones hold some serious weight. Commented Oct 16, 2019 at 19:44
