I have one thing that has not been mentioned yet. Studs are MUCH easier on the threads, especially on an aluminum head. All the load on the threads is a straight pull to hold the parts together with no twisting, galling or potential for cross threading. Studs are a good option and worth the small cost and effort.

 

So to dig up a mildly dead thread.

For those of you who did buy the studs from GM. What did they look like? Were they just your common stud? Did they have either a recessed allen head or a smaller hex head on the end of the stud to use to torque the studs into the head? Were the part numbers listed above for a single stud and single nut or do the numbers correspond to packages of studs/nuts? How about the nuts, were they a carriage nut? Were the nuts of the same hardness of metal as the studs? (it is common in the diesel industry to use nuts of a softer metal so that when they cross thread coming off they do not damage the stud.) Pictures would be nice too if you've got any.

Thanks

they have a hex head on the end of the stud.

 

Good to know, thanks. How about the rest of the questions? Particularly is it one per part number or are there multiple ones in a package? And also, are the nuts a carriage nut?

 

The studs come in packs of 5 and the nuts come in packs of 4, if I remember correctly. The nut looks like those, except the hole is triangular in shape and has some kind of coating (threadlocker i think).

 

The triangular shape aids in locking the nut to the stud also

 

yep....

 

That is good to know, I was going to buy some, but thought that the P/N was for 1 so I really didn't want to spend ~$40 at the dealer for just bolts. Now that I know they come in a set and also that they come with a hex head on the end I am definatly going to order some up from them. Thank you for the help guys.

 

i was at O'Reillys today and they only had a stud kit for my truck no bolts. i dont remember who made em but they had them for my truck and i cant find them on their website :/ i will have to call them tomorrow and get more info. i have a 2002 gmc sierra 5.3

just ordered up a set. Great info, and thanks!
