Hi list,

Does anyone know what the strength/rating of the majority of Spridget nuts 
and bolts are?  Am I right in thinking that in most instances it is SAE grade 
5 or equivalent? 

I haven't come across anything in the UK that appears to be a grade 8 bolt 
where to you get yours from?

What is the big deal with AN bolts - they seem to have a tensile strength 
only slighter higher than the grade 5?  

A terminology question is yield strength when quoted as a different value to 
tensile strength the same as shear or does it mean something else?

On the Spridget some of the nuts and bolts (not many) are black in surface 
colour - any idea on the rating?

Engine & transmission aside, what do you consider are the critcal 
applications for nuts and bolts?  Further, what breakages have you had and 
what grade of nuts and bolts do you know use?

Many thanks


Daniel
