Help with nuts and bolts
Hey Guys,
Starting to put my 77 back together. I have the AIM book.. but I need a way to cross referace the bolts and nuts.. all the AIM says is bolt and part number.
Any PDF's out there that can help me?
Thanks,
PapaJ

Good luck! This has been the biggest source of headache and frustration (plus expense) in the reassembly of my 82. I'm going to see about the previous mentioned catalog on E-Bay. The AIM is worthless for part numbers and I think the Chilton's manual has better illistrations for reassembly.

This information would help anyone who is trying to use AIM for re-assembly of any corvette system.
Has anyone seen a copy of "53-82 Dealer Corvette Parts & Illustration Catalogue" as shown in the previous post; and does it actually identify the actual size bolts and/or fasteners?
This item would be worth the money if it provides the right information.

I have a copy of this and use it all the time. However it does not have the specific information on bolt grade, length, and thread size that you are looking for.

Yes, when the AIM shows; ie, bolt P/N 3817575, there has to be a cross reference book for specs for that bolt.
Will look for Tripoloi book.
Thanks for info.
Joel, not trying to hijack, this would be helpful for a lot of folks.

I have found that the AIM lists part numbers that are not listed in the 53 -72 parts catalog. There is an online PDF for the parts catalog, and I apologize for not having the link handy right now. The parts catalog parts descriptions are pretty well detailed, but even in PDF, parts lookups are very time consuming. Assume that for all drive train and chassis applications, that you need grade 8 bolts. Paragon, and other specialty vendors have many bolts reproduced including correct head markings. There are also vendors like Totally stainless http://totallystainless.com/about_us_gearheads.htm that have the correct bolts in grade 8 stainless (no rust), but it is a good idea to have your old bolts to verify head style, length, and thread.

Maybe he meant 18-8? But I agree with you willem. Replacing a fastner with another made of a harder material could cause the parent material, that the fastner was going through, to wear out or in fact, cause the harder fastner to shear.

Almost anything is out there, or can be made for you.

Grade 8 Stainless
Not to start a pissing contest here, but grade 8, as far as I know, is an ASTM designation used on carbon steel fasteners, only. It is used to designate a number of properties which would be desirable in specific applications including but not limited to tensile strength, shear strength,and ability to stretch before breaking. If I am off on this I apologize, but my concern with the term being crossed over to stainless is that someone might subsitute an inferior propertied stainless bolt to an application that it was not intended with disasterous results. These cars are capable of generating some staggering stresses on fasteners, and I would hate to see anyone hurt because of rust prevention. If you check the wording of these vendors ads, I think they kind of fudge around this point.

Stainless bolts are not as strong as grade 8. When building my chassis, I would take take a handfull of the original bolts to the hardware store and match them up as I needed them. I little at a time doesn't hurt the wallet as much. BTW, the colored GR. 8 bolts look nice.

When an mech engineer thinks of grade 8, he may automatically think of the def of the spec and the bolt's intended application .
When average mechanics and most other people think of grade 8, it probably just means to them it's stronger than grade 5.
In most cases substituting a generic ss bolt would be harmless, such as a brake line clamp bolt, but the trailing arm spring bolt replacement should not be a careless swap.
There are though, stainless bolts that meet and exceed the grade 8 strengths and properties, some made of 400 series stainless and beyond superalloys, many manufactured by SRS Technologies.
We used to use a Lamalloy L9 designated bolt, (higher rated than grade 8, but not stainless) but we were also careful enough to do destructive testing, not only on the bolt, but the assembly as a whole to have a proof rating.
It would be interesting to compile a list of the more difficult bolts on a C3 that owners would want to convert and investigate it properly.
BTW, you were right on with the marketing by not ARP, but the reseller, ARP says the stainless bolts are not grade 8, but have a tensile of approx 170k
