Is there any difference between wood screw and anchor screws?

Question

I have purchased a screws and plug set from IKEA. However, I want to secure a bookshelf on a stud.

May I use the screws from the set? Is there any difference between screws with anchors and wood screws?

Answer 1

Anchor screws and those designed specifically for wood have very similar (if not identical) thread pitch. In fact, anchors often ship with standard pan-head wood screws. I've used them interchangeably many times.

The critical concerns are diameter (larger diameter offers substantially more holding power) and length.
