Definition

Noun

  • Protrusions on the shank of an anchor that keep the stock in place.

Origin

Probably earlier than the early 17th century. From Old English, but unknown when it came to be used in such a fashion.

Comments

The nuts are balls on the ends of the stock of an Admiralty pattern anchor. They prevent the stock from penetrating the ground and force it to lie flat so the flukes, at right angles, are driven into the bottom to provide a good hold.
