Usage

Origin & History

Origins and dates here are approximate summaries. Many idioms have disputed or unknown origins, and not every date has been checked against a historical dictionary, so treat specific dates and stories as a starting point rather than a citation.

A carpentry image: a hammer blow works best when it lands squarely on the nail head. Missing the head bends the nail or wastes effort.

Versions of the phrase have appeared in English since at least the 16th century, long before modern carpentry tools changed the image.
