Nails have better flexibility and can bend as the wood moves. This way the nail is essentially wedging itself between the fibers of the wood, rather than cutting the fibers and introducing a split.
What kind of screws will not split wood?
The MDF screws come in the same sizes as regular wood screws and feature star-drive heads, but are designed to eliminate splitting and the need for predrilling.
Do nails or screws split wood?
Nails are the fastener of choice when laying down hardwood floorboards because they’re not as likely to split the wood as screws and don’t mar the surface with screw heads. Nails also flex a bit more, to allow for the natural expansion and contraction of the wood, without loosening their grip.
How do you reinforce wood?
The easiest and most effective way to strengthen wood is to use a wood hardener. In contrast with Polycryl, most wood hardeners are not water-soluble, so they are usually more rigid and reliable in the long run. However, wood hardeners mostly work in pieces of wood that are too old.

How do you repair cracked exterior wood?
Use exterior wood filler to fill and patch cracks in the trim itself as long as it is still structurally sound. First, rough up the surface with coarse sandpaper to ensure a good bond. Then apply wood filler with a putty knife. When it’s hard and dry, sand it level with a medium- or fine-grit sandpaper.
What causes cracks in wood?
Cracks or checks occur when wood shrinks as it dries. Wood shrinks roughly twice as much along the growth rings as it does across the rings and it is this uneven shrinkage that causes checks to develop. Checking can be controlled in smaller sized 4/4 -10/4 lumber, because it’s easier to dry.
Why do screws shear and nails bend?
If you apply enough shear force to the side of a screw, it snaps. Screws will keep wood together when faced with vertical force and won’t break down when lots of vertical force is applied to them. Nails are able to bend under pressure, and rarely snap when subjected to shear force. They’ve got a lot of shear strength.
Why are screws brittle?

Do screws weaken wood?
When you drive screws into wood without drilling pilot holes, you’re essentially pushing wood out of the way to make room for the screw. That displaced wood puts more pressure on the wood surrounding the screw, which can lead to splitting and cracking, weakening the wood over time.
