Grade 8 NUTS

Hi guys. I have some questions on grade 8 NUTS. Notice I said NUTS. I am well aware of how to identify a grade 8 BOLT, I'm just curious about nut identification. I'm also wondering how important a grade 8 nut would be. I'm thinking a grade 5 would be fine depending on which way the shear force is applied. Thoughts?????

Typically the Grade 8 nuts will have the gold finish like the grade 8 bolts assuming they don't have a coating (zinc). The benefit of the GR8 nut in my opinion is if they are located in a place you can't get socket or box wrench. A open end or crescent could round a GR5 but the hardness of the GR8 might help prevent it. If I weld a nut to something I ALWAYS use the GR8... Others may have their own opinion...

Thanks man! I agree the Grade 8's are usually w/ the gold finish.... But not always. X2 on the rounding over. Nice point. I guess my question is how do I truly know I've got a grade 8? Markings??

The nuts to be used with Grade 8 fasteners are almost always gold colored and have a digit or number stamped on one side.

Always use these nuts and washers on Grade 8 bolts.

Nice link. Unfortunately it just leads to more questions. Clearly those nuts are graded. Back to my original question... Again, none of those gradings, correlate w/ bolt gradings. Could you help me out w/ bolt Vs. nut grading?

You're right, those are being sold as grade 8 nuts. I just posted up the link to the standard set by other folks

FWIW, this is what a grade 8 nut looks like



I went out and checked the Gr.8 nut drawer in my garage, and they look like this.

My honest apology for arguing with you online. It is entirely possible that the link to the table I posted has an incomplete listing from ASTM, SAE & ISO.

There are grade 8 and grade 5 nuts and various other grades as well. A cursory search turned this up which will help and there is a more complete version that I've seen and don't feel like looking for.

Grades 5 and 8 Finished Hex Nuts

I buy and use specified grade 8 and 5 nuts on a weekly basis.
