Selecting the Correct Fastener: What to Consider
Material: Select a bolt material that is suitable for your environment. Stainless steel bolts will withstand corrosion, and zinc-plated bolts are perfect for use indoors.
Size and Length: Make sure the fastener is appropriate for your materials. Too short and it will not hold, and too long and it can ruin the surface.
Thread Type: It has coarse threads for a better grip in wood. Moreover, fine threads are best used in metal.

A Personal Story: The Wobbly Chair Problem
A few years back, I owned a chair that would wobble whenever I sat on it. No matter how frequently I would tighten the screws, it simply wouldn't stay firm. A little bit of research later, I figured out that I had employed the incorrect type of screws—a quick switch over to proper wood screws, and—voilà!—wobbling ceased.
A brief lesson stuck with me: the right fastener can make all the difference.
