Determining shear on drywall anchors / toggle bolts

You have studs, so the simple solution would be a 16" or larger shelf bracket attached to a stud, so the 15" radius of the 30" diameter chandelier doesn't hit the wall. Only have to ...

How can I hang heavy things from this drywall and metal ceiling, without cutting drywall?

What you have there is a steel web truss with hat channel attached to the bottom. The hat channel gives you an attachment point for the drywall as it cannot span the 4' spacing that you have between ...

How should I deal with shelf anchors which are deeper than the framing slats?

That is a bit of a head-scratcher. I have two potential solutions. You'll need to investigate the first to see if it's viable. Shorten the screw. Properly piloted, 45mm of thread is plenty for any ...

Ways to attach a coat-hanger between two closets (heavy load)

You basically want to run a bar between two outside cabinet walls. That should be easy, even with particle board. Use a couple of these per bar: https://www.amazon.com/Creatyi-Stainless-Brackets-...

How do I determine whether a ceiling of unknown material is safe to hang speakers from, and identify the best spot to drill?

Use the beams. If that's a pre-manufactured kit-type sunroom, (as is moderately common for such add-ons) there may well be nothing suitable to mount to in the ceiling structure. Could easily be ...

Hanging Chair from Ceiling in Apartment?

Expanding on the comments already in place: your ceiling absolutely cannot hold that chair without anchoring into a joist one way or another. You are correct, the expansion screws will not work for ...

How to attach header for a barn door to the face of columns?

8mm screws seem too small. Thread area is compounded with diameter, so even a small increase in size yields much greater hold. Also, you need to consider shear strength (flex and bending). Shear in ...

Can I drill a bracket for a hanging basket into this column on our deck or will it weaken it?

A few screws will not hurt. Even a few hundred screws will not hurt. Those columns can hold quite a few plant baskets with no problem. You might want to put in caulking in and around the holes to ...

What mounting solution should be used to mount this wine rack?

You want to find studs. Do not use drywall anchors or else you will find a thousand dollar bottle of wine staining the carpet. I would use a nice backing board(stained wood) and mount it as a shelf, ...

Securing a bookshelf to a shared (concrete?) townhouse wall

On a painted wall like that plaster filler will work just as well as it does on drywall. I would go with the powdered stuff as it sets up faster. So just drill holes and use concrete anchors, pick a ...

How can I hang heavy things from this drywall and metal ceiling, without cutting drywall?

I think you're right to avoid using ceiling drywall alone to support any but the lightest of things. The furring strips between the drywall and the trusses will hold a fair amount, say 10 pounds at ...

What screw should be used to secure plywood blocking into metal studs?

For a network rack ~100 lbs I think this is overkill. Not the plywood - that's perfect. But opening up the wall is just not necessary, and it means a lot of extra work to patch the drywall. In ...

"Sheet metal" screws will work fine in wood. drywall screws will also work in the application despite having a bugle head instead of a pan head. The screw in the illustration is actually a ...

Where can I find a specific screw (pan head #10 wood screw) for a wall-mounted speaker

Visit an old-school hardware store and I'm sure they'll have what you need. Just make sure to actually hit a stud and not just into drywall.

How to suspend small cabinet from ceiling?

If you really don't want to use wall anchors, i would probably get two boards, maybe 1x3, 16" long each and screw them into the studs. Then attach your small cabinet to the two boards. I did ...

What screw should be used to secure plywood blocking into metal studs?

The screws should be calibrated to the material at the back of the connection, wood in this case. They should be long enough to stick out the back of the plywood. There's a risk of overtightening to ...

How can I tell if I drilled too far into a ceiling joist?

That is a lag screw. It is likely you drilled the hole too big. More likely you drilled into a piece of wood that is only supporting the ceiling drywall. (dead wood) This is a 2x4 that is laid on the ...
