Attach a stud to a drywall for countertop

[NiklasLi]

Hi, I'm going to set up a countertop that will rest on cabinets on one side, but will be attached to the wall on the other side.

My idea was to attach a 45*45 mm piece of wood to the wall for the countertop to rest on. Does that sound like a good plan?

My concern is how to attach the wood to a drywall. In one spot, I can fasten it with a screw right into the stud behind the drywall. How long should that screw be? Type of screw?
How do I attach where there is no stud? Will drywall anchors work? What kind?

Grateful for tips and advice

Hello, I'm going to set up a countertop where one half rests on cabinets, but the other half should be attached to the wall.

My idea was to attach a 45*45 mm beam to the wall for the countertop to rest on. Does that sound like a good plan?

My question is how to attach the beam to a drywall. In one spot I can attach it with a screw directly into the beam behind the drywall. How long should that screw be? Type of screw?
How do I attach where there's no beam? Would drywall anchors work? Which type?

Wood screw for the beam, about 90mm long.

Apply glue behind the 45 beam that you are going to screw.

Is there only going to be cabinets on one part of the countertop?
What will be under the remaining part, if it is to be concealed by something, you could put a support between the beam and the floor.

If it's going to be open underneath, it might look nicer with some angle brackets, which are screwed in with molly bolts.

It should be open, desktop space. Do you mean angle bracket between the stud and the wall?

thanks for the response

It should be open, desk space. Do you mean angle iron between the bracket and the wall?

thanks for the reply

No, I was thinking more about using angle iron for the board to rest on. If it should be open, I would skip the bracket and just use angle iron.

Aha, does it need to be any specific angle brackets? How many do you think you need?
The hole is about 75cm wide and the board is 63 cm deep. It is an Ikea laminate board.

And as you wrote before. Wood screws into the stud and molly plugs into the drywall?

Either you buy iron that is about 500mm long
Alternatively, four small simple ones. Doesn't need to be too advanced, it will rest on a cabinet at one end.

Yes, screw in a wood screw into the stud, (doesn't need to be 90 long if you're going to place angle irons.)
Molly in the plasterboard.

It will hold.
