Choosing the Correct Nut
Match both the thread diameter and thread type to your bolt or stud. BSW and UNC threads are different thread forms, even where the diameter and threads per inch are the same. Use these nuts with matching BSW fasteners.
The across-flats measurements shown are the actual hexagon widths, not Whitworth spanner markings. Choose a spanner or socket to suit these dimensions.
