How strong are deck screws?

How far should a screw penetrate wood?
This pilot hole should be deep enough so that it penetrates the wood a distance of about one-half to two-thirds of the screw’s threaded length. If you are planning to countersink the screw head, a third hole, equal to the diameter of the head, will be needed at the surface.
Are screws stronger in tension or shear?
they also designed for tolerating shear loads. therefore, it is obvious to be stronger in tension as its ductile behavior. In-plane bending also results in a tension to the cross section and consequently is stronger than shear.
How much weight can a screw hold in drywall without anchors?
How much weight can drywall hold without anchors? This can be 5 to 10 pounds, but keep in mind that the drywall is an extremely brittle material and, it is not strong enough to hold the weight for a longer period of time.
How big a screw do I need?
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. Most of the time you’ll want to go with a #8 screw.
