It is largely obsolete for new designs but remains in use for maintaining and restoring older British machinery, such as classic cars, motorcycles, and industrial equipment.
Whitworth threads have a different thread angle (55 degrees vs. 60 degrees for metric/Unified), pitch, and measurement system (imperial inches vs. millimetres). They are not interchangeable.
They are considered specialty tools. They can be purchased from suppliers specialising in classic vehicle parts, certain engineering suppliers, or online historical tool merchants, but not from standard hardware stores.
It was adopted across the British Empire and was influential internationally in the 19th century. However, it was largely superseded by other standards (Unified, metric) in the 20th century outside niche restoration contexts.
