Imperial Combination Spanner Set - Set of 12 US Size Spanners

Product Information

This was in the days when Great Britain had a large manufacturing base and didnt simply import cheap junk from the far east. After around 1970, wheel nut sizes have virtually been globally standardized at 19mm, an almost exact match for a 3/4in AF socket in Britain. Usually applied to spanners in imerial (inch based) sizes the smallest increments are normally 1/16inch (for example 7/16,1/2,9/16 etc) but some smaller spanners are marked in 1/32 inch increments.

Size Spanner do I need? - U-Bolts-R-Us What Size Spanner do I need? - U-Bolts-R-Us

These threads are designated by a number between 1/16 and 6 that originates from the nominal internal diameter (i/d) in inches of a steel pipe for which these threads were designed. This is supposed to mean that the tool will definitely fit bolts and nuts with all those thread sizes. This means that if the size stamped on a spanner is 1/8th BSW, the distance between the flats of the spanner won’t be 1/8th of an inch. A particularly common configuration for spanner or wrench combination sets is a kit that offers both ring spanner and regular jaw-type functionality, either as two separate collections within the same box or as a single set with different head types at either end.Most spanners do have their size stamped on them, but this is usually the distance across the flats of the nut and can be confusing, so we will help you to determine the size you need, and show why you should not just grab one that seems close enough.
