The Whitworth

The Whitworth refers to a standardized system for measuring and creating threads on screws and bolts, developed in the 19th century by Sir Joseph Whitworth. It ensures that bolts and nuts from different manufacturers fit together properly. The system includes specific measurements for thread diameter and pitch (the distance between threads). In the imperial system, the Whitworth thread is known for its rounded "V" shape. This standardization improved manufacturing and repair processes across industries, especially in Britain, by making sure threaded parts are compatible and reliable.
