Imperial Combination Spanner Set - Set of 12 US Size Spanners

Product Information

British Standard Whitworth ( BSW) is an imperial-unit-based screw thread standard, devised and specified by Joseph Whitworth in 1841 and later adopted as a British Standard. It was the world's first national screw thread standard, and is the basis for many other standards, such as BSF, BSP, BSCon, and BSCopper. Sizes are only listed under the 'fits' column where the imperial size is in general use (or was). 29/32" may be a good metric fit, but no-one has such size tools. It is always important to use the correct fitting spanner. Otherwise, the excess play exerted may slip the spanner and cause damage to the bolt or nut or cause personal injury.
