Pre-drill.
Without a pilot hole, the screw is essentially wedging itself into the wood. This puts a lot more pressure on the screw as well as the wood. In weak woods, this can cause a split; with weak screws, the screw can break. Drill using a wood bit of a diameter slightly smaller than the screw.
similarly, What drill bit do you use for screws?
Almost all drill bits have their dimensions labeled on the actual bit. For screws, you’ll need to find the box or bag that they came in. For a size 2 screw, use a 1/16 bit. For a size 9 screw, use a 9/64 bit.

How do you fix a screw that keeps coming loose in drywall?
The easy repair is to replace it with a larger conical anchor, but that anchor will probably also pull out in time. A more effective solution is to replace it with a plastic screw-in anchor, a molly bolt or a toggle bolt. The last two types of anchors clamp against the back of the drywall for extra holding power.

Drilling, nailing and screwing can all cause concrete to crack if they’re not done properly. Although it seems like a very tough material, concrete is in fact extremely brittle and prone to cracking. What’s important to stop concrete cracks when doing these things is knowing how to do them properly.
Why are my Tapcon screws breaking?
The dust can build up and create a situation where the screw is unable to be fully inserted in the hole and if too much torque is applied, the Tapcon® screw may break of shear off.
What is the strongest concrete anchor?

Why do carpenters prefer screws to nails?
Screws are more brittle than nails. … Nails don’t have a threaded shaft, so they aren’t as brittle as screws. And in turn, they offer greater tensile strength, making them desirable for construction and carpentry applications.
How do I choose a screw size?
The most important factor in screw selection is length. The general rule of thumb is that the screw should enter at least half the thickness of the bottom material, e.g. 3/4″ into a 2 x 4. The other factor is the screw’s diameter, or gauge. Screws come in gauges 2 through 16.

Can you screw into wood without drilling?
For rough construction, you can usually just power screws into place without drilling a hole.

When driving screws, drill a pilot hole to prevent the wood from splitting.
