Grade 8 vs. Stainless?

"None of which are universally acceptable" is right!

I have to unscrew some bolts tonight. Then screw the bolts back in...

Funny,

One of our students graduated last year and now works at his dream job for Lockheed as a AE designer on the new Orion Vehicle. He is over the fasteners for the entire project, and he said, they get lots of stuff off the shelf at mcmaster.com... wild!

That said, I found a "Ultra High Corrosion Resistant Finish" on a socket head bolt that was created for the salt marine enviornment. It is 30% stronger than a grade 8 bolt in the same size. They were about 11 bucks for a box of 25. They look like a silver powder coat or something... pretty cool.

Those are very cool!

Thanks, I bought a few sizes to use on the trailer, I am going to use these exclusively and nylocks and call it a day.

yep, to answer a way back questions, all types of stainless are heat treatable to all levels of "hardness" just not as high as some carbon steels.
