Nautical Term: Thread
Definition of Thread
A nautical term referring to the helix or spiral part of a screw, such as a wood screw or a machine screw used in marine applications. This part of the screw engages with the material being screwed into, providing the necessary torque to secure the screw.
For example, in a repair situation on a ship, a crew member might use a drill with a machine screw and a washer, then apply the necessary torque with a torque wrench. The spiral part of the screw, also known as the thread, is what engages with the material being screwed into, providing the necessary grip and holding power to secure the screw.
