Minimum Yield Strength for "tensile strength class 10" nut = ?

[olyoly]

Does anybody have a reference that answers this question? I see the term here:

I've heard that a "tensile strength class 10" nut is meant for use with a Property Class 10.9 bolt, but I can't find any documentation to support this.

I've got in my notes:
The strength class of the nut should correspond to the first number of the strength class of the bolt.

I've also seen lots of bolt/nut tables (amongst others in manufacturer's catalogues) that support this.

I'm sorry but I can't find any reference though...

Look at ASTM A563M. Table X1.1 contains a nut/bolt suitability guide.

BS4190 Table 9 gives recommended bolt and nut combinations. For a grade 10.9 bolt, a grade 10 or a grade 12 nut is recommended.

Thanks for the posts everybody! The BS41090 reference is exactly what I was looking for.

Table 4 in BS3692 also gives bolt and nut combinations.

BS4190 is for ordinary black bolts

BS3692 is for precision bolts
