You can, but it's often unnecessary and can split the wood. Wood screws are designed for better holding power in wood. Self-tapping screws are primarily for metal, plastic, or other materials where cutting a clean thread is beneficial.

Often, yes, especially in harder materials or to prevent wandering. The pilot hole diameter is slightly smaller than the screw's major diameter. In soft materials like thin plastic or sheet metal, a pilot hole may be optional.

Common causes include using too small a pilot hole (creating excessive torque), driving it too fast without enough axial pressure (causing it to 'chatter' and snap), using it in material that is too hard (e.g., hardened steel), or using a low-quality or incorrect screw type.

A type of screw that creates its own mating thread in the material into which it is driven, eliminating the need for a pre-drilled and tapped hole.
