Header bolts size

Ok one of the 100 little things I need to do is find some header bolts as I lost the manifold bolts when they were taken off and for some reason I cant seem to find them or at least decently priced ones. I have found some online but they dont say the size or thread pattern, I know they are metric Im thinking M8x1 or 1.25 does anyone know the size I need for my 07 5.3 ? and where to go to get some ? I went to the local Home Depot but all they had was SAE grade 8 not in metric tho...I refuse to pay the 30-60 bucks that these places i found want. they are just freaken bolts, somewhere there has to be a place I can go to find these at a reasonable price... thanks for any help oh and I am going with some shorty headers if that makes a difference

Re: Header bolts size

What I am finding it is an 8mm x 1.25 thread. Hit up lowes or home depot you should be able to get them for a couple bucks.

If you have ACE, they always help me, especially if you have one of the "old school" mom n pop owned ones. I've always had the hardware guy throw me a bone of expensive hardware as an enthusiast. OTherwise, Fastenal is a really nice resource too, just be patient with the employees...they don't tend to work auto-specific.

They are black oxide bolts, nothing special....if you want them,I don't need anything , but the mail charge Shoot me a PM, on the zip/addy, & I trust that you will cover the shipping cost....or I don't really care about it....just pay it forward, to the next player longhorn

Another known Good Dude on this forum. I've been awestruck with the transparent generosity on this forum. I've been given parts by various members 3-4 times now, and always made a point to pay it forward. **knock on wood** but that sort of act actually works here.



Now,

on my way to ace hardware I found a fastenal and found those m8 bolts in the gold color bolts. They have a zinc coating. I also found that metric bolts are not rated like standard is grade rated metric is class rated these bolts are class 10.8 which is close to the grade 8 in sae

Thanks everyone now that's one less thing I need to worry about

Re: Header bolts size

Ya, thats what anti-seize was for...but most of us forget it. Thats also why the stud-style replacement has gotten more popular, as its much less likely to sheer at the nut.

I wonder if they are even grade 8 or class 10.9 metric....been researching this and seems to be a very popular topic so I guess it happens alot ! I think I was seeing red when I discovered this purple after the second one.

Re: Header bolts size

I went with stainless bolts. not as common, as they're metric, but they are out there and should hold up pretty good.
