Screws can rip right through certain materials, making them a poor fastener choice for weak, thin woods. Door skin (1/8-inch plywood) and similar materials may allow screw heads to sink or rip right through. Very soft woods such as balsa will also sink or dent under the pressure of a screw head being driven in.

What are the advantages of using screws over nails?
While nails have more flexibility, screws have more tensile strength. Tensile strength refers to a material’s ability to resist breaking under pressure. This makes screws better for projects when joined pieces are under tension or bearing weight, like porch railings or kitchen cabinetry.
What side do you lay decking boards? What is the correct way to lay decking? Any decking board manufacturer or professional will tell you: “The proper way to install a decking board is ridge side down.” The ridges are designed to allow for airflow, to stop moisture sitting in the ridge, and allow for a stronger structure.
Do decking boards need gaps?
Proper Gap between Decking Boards
When installing decking boards, make sure to leave 1/4 to 1/8 inch gaps in between them. This gap will make sure that the decking can breathe, have sufficient drainage, and make it easier to clean.
What side should be up on deck boards? This then leads us to the most debated question about installing deck boards: crown up or down. The direction affects how the boards shape over time – cupping or crowning. Deck boards should crown up – bark side down.
What is a Phillip screwdriver used for?

Why do carpenters prefer screws to nails? Screws are, in fact, able to create a more secure hold when joining objects than nails because they have a threaded shaft. With that said, nails offer greater tensile strength.
What are the disadvantages of screw jack?
Limitations. Screw jacks are limited in their lifting capacity. Increasing load increases friction within the screw threads. A fine pitch thread, which would increase the advantage of the screw, also reduces the speed of which the jack can operate.
What are the disadvantages of nails?
Cons: Perhaps the biggest con with nails is that they aren’t as easy to remove as screws. In fact, removing nails can frequently cause cosmetic damage to the item you’re removing them from.
Do nails weaken wood? When installing nails the force is compressively driven straight into the material, which theoretically increases the frictional pressure within the nail hole and increases its strength; but it can also split the wood it’s being driven into if not spaced and sized appropriately.
How long should deck board screws be?
Deck screws measuring 2 ½ inches and 3 inches usually work best for fastening railings, deck boards, and joists, while 6-inch deck screws are necessary for 4×4 posts.

Should deck boards run parallel or perpendicular to house?
Decking running parallel to the house makes the deck look wider and blends the deck into the house. If the decking runs perpendicular, the deck looks long and extending far out, away from the house.
Do deck boards shrink or expand? Deck boards will shrink, and not only that, they will even expand. Fibers have the ability to hold moisture in them. So when the outside environment is humid, the fibers collect moisture and expand, leading the boards to expand. In the dryer seasons, they lose moisture and shrink as a result.
Should deck boards be bark side up or down?
The usual reason given for placing deck boards bark-side up or siding bark-side out is to reduce cupping, a form of warp. Cupping results from the shrinking of the top and swelling of the bottom of the wood, which are caused by exposure to moisture and drying by the sun.
