I built a sit/stand desk using some legs attached a piece of wood I had. I don't know what the wood is but is it is 1" thick and quite soft. The screws supplied were 5/8. Since I have monitors clamped on the back of the desk it tilts to the back slightly and puts pressure on the screws in the front. On one side two of the screws have fallen out.

So I am looking for suggestions on ways to strengthen this connection. I thought about fatter 5/8" screws? Or some kind of plate to distribute the pressure?

Any thoughts? Thanks.

Sorry that I wasn’t clear.

These are the legs I used:

I am using a desk top made of recycled wood. 1” thick.

Perhaps the question makes more sense now?

    I see nothing in the picture that relates to table legs. Commented Mar 28 at 15:06
  • Furniture repair is off topic here. Please see the help center and take the tour. If this is more of a woodworking question, which might be considered on topic, please provide a photo with some context. The problem relates to the overall desk structure, not just this screw hole.

    Seeing how the legs are connected to the desk will help. 5/8 long screws should be use to attach thin bracket to wood, not legs. If that black angle thing is suppose to be a leg, I might think about getting more solid legs. Commented Mar 28 at 15:24
  • forget wood screws ... use a T-nut and a bolt ... this may help m.youtube.com/watch?v=HVfkxJiqLkA Commented Mar 28 at 19:27
  • The rubber washers and the screws were supplied with the legs. Legs (link above) are highly rated lifting desk legs. One assumes the screws are so small as they expect weight of wood desk top keeps things in place. But I mounted two ultrawide monitors on desk which pulled the desk in the back down due to the weight. T nut wouldn’t work? As up it would be visible on the desktop? Commented Mar 30 at 1:55

Notice that the angle you are screwing through is offset by washers.

If the angle and washers are 1/8" each, a 5/8" screw is grabbing only 3/8" max.

Since the table is 1" thick, even a 7/8"-1" screw would work.

  • 3/8 includes the tip. Maybe 1/8 of full shank, only 1 or 2 threads holding the wood right now. Yikes. Hey Simon what is the black spacer between the leg and the board, why is it there? Commented Mar 28 at 18:00
  • Let alone whatever that is underneath the angle. Commented Mar 28 at 18:01
  • That is what I was talking about. Do you also see a washer in the fuzzy photo between the screw head and metal? Now I'm wondering why OP would add all this hardware, or, if it came with the legs, why they supplied such short screws. Commented Mar 28 at 18:05
  • I'm guessing that the washers were originally designed to fit into a recess of some kind to increase twisting resistance. Doesn't explain the short screws, though. Did these legs come from one of those plastic tabletops you see at Costco? Commented Mar 28 at 18:09
