'Pin' in the Bible

Then Jael Heber's wife took a tent peg, and took a hammer in her hand, and went softly to him, and struck the pin into his temples, and it pierced through into the ground; for he was in a deep sleep; so he swooned and died.

She fastened it with the pin, and said to him, "The Philistines are on you, Samson!" He awakened out of his sleep, and plucked away the pin of the beam, and the web.
