Intake manifold torque

MoparLeo said

I think you said "'hardware grade 5". I hope those are not from any hardware store. Only automotive grade fasteners are designed to be used on autos. Rolled threads, specials shoulders etc...
hat type and quality of torque wrench are you using ?
Magnum intake torque spec is 2 step. First to 16 lbs. Then torque to 23-25 lbs. This is with a Magnum bolt pattern intake.

MoparLeo, could you tell me where you are getting this information?
The reason I ask, is that it seems to be in direct contradiction to the FSM and several post from this forum.
Not saying you are wrong, but would like to know where you are sourcing the information.

To answer your comments,
1. The bolts are hardware, (home depot grade 5) but upon doing a search for "intake bolts" on this forum, several members, including magnummopar recommended hardware bolts, and to replace the factory bolts due to breaking from corrosion.
2. The type of torque wrench was a cheap harbor freight click style for the in. lb settings. The 12ft. lbs was set with a craftsman beam style.
3. The torque ratings you stated are different then the FSM.

Thanks for your post.
