Juq460 ^new^ Review

As the global automotive industry transitioned to metric fasteners (Metric ISO screw threads), standards like BSW and BSF became obsolete in new designs.

SAE J460 provided recommendations for the dimensions of holes used with British Standard Whitworth (BSW) and British Standard Fine (BSF) screw threads. These thread forms were the dominant standard in the United Kingdom and the British automotive industry before the widespread adoption of the metric ISO thread system. juq460

SAE J460 was a specialized standard facilitating the use of British-threaded fasteners in automotive applications. Due to the obsolescence of Whitworth and Fine threads in modern manufacturing, the standard has been cancelled. Contemporary engineers should refer to ISO metric standards, while vintage restorers may use historical reference charts derived from J460 for legacy parts.
