Nautical Term: Spote-faced

Definition of Spote-faced

The term ‘spote-faced’ refers to a condition where an annular backing, typically made of cement or putty, has been applied around a bolt hole. This backing allows a nut or head to seat evenly, preventing any uneven pressure or torque. For instance, in shipbuilding, the ‘spote-faced’ technique is commonly used to ensure that the nuts and bolts holding the plates together are correctly torqued, improving the overall structural integrity of the vessel.
