Bolt Grade Comparo?

[Hossbaby50]

Anyone have a link to a website with numbers on the strengths of the different Grade bolts? I need the numbers for Grade 5,8,10 of the 9/16" and 5/8" sizes

Anyone know of a site or the strengths of studs? I need to figure out what I am going to do with my sheared steering studs.

1" extended over stock 9/16" steering studs apparently aren't that tough. I need to get something tougher. Thanks

Harley

I can't copy this stuff very well, but there are a couple of spec. charts on there. I saw a class 10 listed but no grade 10

How about the ARP studs ORD is now offering?

 

[Hossbaby50]

I don't think the ARP studs are out for the D44 crossover yet. I put up a post in there forum to see on availbility. Thanks

Me too, was so curious I did a search and found lots of these :

Chart I found 1

Chart I found 2

Lots of info out there, I even read where since the 80's there are many low grade knockoffs out there , so always buy bolts from reputable source. /forums/images/graemlins/k5.gif

6 points hardware has tons of books on that. If you catch them on a slow day they will help you look up stuff for hours.

The Machinery's Handbook has all of this info and more. It contains information about every type of mechanical component, fastener, material and everything else. It is an invaluable tool to have. They sell them at Barne's and Noble.
