Are higher grade bolts more brittle?
Grade 10.9
Ultimate Tensile Strength 10MPa
Carbon Content 0.9%
This is a very strong bolt. If your application calls for a high
tensile bolt then this is a good choice. You could go for a Grade 12,
but this might be overkill. If the nuts are old, you should think
about getting new ones.
