Thread: Grade 5 or 8?

Tweet

Don,

I noticed Grade 5 bolts in my suspension. When I called Pete & Jakes about it, they fed me the old myth also. That's the only disappointment I've ever had with Jerry and Jason Slover.

Don't you have a top to chop? It's only 12:50.

Today is our day of rest.............but tomorrow night we can stay late because Dan doesn't have to work Saturday.

That`s a mighty fine point to bring up denny! To be honest, i never really thought about it that way. It goes with the saying " a chain is as strong as its weakest link".

Dave, I have also been watching the McMaster hardware with respect to the country of origin. The Gr 8 bolts usually have "made in USA" on the boxes but the nuts and washers are not always the same....I have some Gr 8 washers (sometimes called "thick") that are not 'Merican.

IF the manufacturer is quality oriented, it doesnt matter where the part is made (from a quality perspective)... there are crappy bolts made in the USA. However, I personally feel that stuff gets made in China because they can mimic the look of quality without the quality materials. Just like a Chinese wrench, the thing looks fine from 10 feet away but the material is junk (just like korean cars).

I wanted to get engine stand bolts last week for my engine. Summit sells a 16 bolt set for 6.95 or so tha is universal for standard bolts. All grade 8. I went to napa to just buy the same bolts and they wanted 2$ each(32.00 for the same set!) I bought the summit ones, and a fender protector for a lot less, they arrived in the mail the next morning! Pretty good! Today if I get to bed soon, I'll get that dang engine out!Good night!

If you think NAPA is expensive, try Home Depot or Lowe's. . . .

Be real careful of the Home Despot bolts - they are usually Crown Bolt and are not much in the way of quality and IMO, improperly rated. Lowe's used to be Rockford, but now....??? EXPENSIVE

I'm almost ready to hoist the engine out, do you think it would be ok to connect the chains to the exhaust bolts using the exhaust bolts? to lift the 460 out of the truck? Also this is a bit of a highjack(sorry), but along the same lines, can I unbolt the tranny(c6) housing from the engine and just pull the engine or do I need to pull the whole thing out at once?

Thanks Denny. I will go down to Napa and buy a couple of exhaust bolts in number 8s as one did snap coming out, to unbolt the converter from the fly wheel, I take it there is an inspection plate I can reomve to get at it?

Dave,

I don't buy structural bolts from HD/Lowe's. I was just noting the price. They really, really hose you on stainless.

Jack,
Who can afford many 1/4-20x1" SS at over a buck each there. Even their standard Gr 5 and 8 fasteners are outrageous - if they even have the size you need. I do occasionally get some Gr 8's from Tractor Supply though and use them in place of any Gr 5

Generally I buy a bunch of common sizes of SS from Gardner Wescott or Totally Stainless at a show like York. Then more come from McMaster Carr and a guy in MA. I probably have well over $1000 of bolts and nuts - but very few Gr 2

We dont use anything but grade 8 or better on the "Cup" cars I work on, and I've seen them bashed into alot of walls. The suspension bolts rarely ever break. Grade 8 all the way. Sean

thats for sure, here if u get caught without grade 8 bolts in the motor mounts and stands u go home

Glad you all agree!! Its just like a chic, if 5 is good, then 8 is better!!! Seems like the original thread agree`s, 8 is the way to go. And it was not speedway, it was fatmans.


Lets turn this a different direction, what non critical bolts do you use and where? I say use the best, cause i really do not like being stuck on the side of the road!!

i try to use grade 8 everywhere, suspension,engine mounting, of course grade 8's on the harness's, fuell cell , battery hold-down, know why? because you never know when it'll happen thats why.
