Do you need a plug for a wood screw?

A plug is not strictly necessary for a wood screw, but it can be beneficial in certain situations. When you want to achieve a clean, finished look or conceal the screw head, using a plug—typically made from wood—can help. Additionally, plugs can provide extra strength and stability to the joint by filling the hole left by the screw. However, in many cases, wood screws can be used effectively without plugs, especially when aesthetics are not a concern.
