Can a screw be too long?
Machine screws that are too long might not tighten down, and overly long wood screws are worse: They might poke through the other side of your material. In a pinch, you can cut a screw down to the proper size. In any case, cutting screws down to the necessary length is often easier than a trip to the hardware store.
Are you supposed to drill into a stud?

How far behind drywall is stud?
What is a wall stud? Studs are vertical 2 by 4 inch beams that support the frame of your home. You can find them behind your drywall, usually spaced 16 or 24 inches apart. Since studs are made of thick and sturdy wood or metal, they can securely hold screws better than wall materials like drywall.
Why is it so hard to screw into a stud?
The primary reason your screw won’t go into the wood is that it’s reached a particularly dense section of wood, and needs a bit more force. To mitigate the issue, drill a larger pilot hole, use a better quality screw, or get a more powerful drill/driver.
Why can’t I drill into stud?
The reason why you can’t drill through a stud could be a dull drill bit, failed drill battery, wrong drill rotation direction or an impenetrable metal/steel member of the wall structure.
Why is my drill not going through the stud?

How much weight can a screw in a stud hold?
A screw in a stud can hold between 80 and 100 pounds. Be sure to distribute the weight across as many as you can. The easiest way to increase the amount of weight a screw in a stud can hold is to simply double up. If you have room for a second or a third screw, just add more.
Do you need an anchor for a stud?
Wood screws directly into a stud are going to be many times stronger then drywall anchors. When you have hit a stud, use a screw. When you are just in the drywall, use a drywall anchor. Drilling out the strong wood to replace with weak plastic doesn’t make any sense.
Can a screw be longer than the anchor?
Since the purpose of a drywall anchor is to stabilize a screw, it must be at least one size bigger than the screw.
