Edelbrock Intake Bolt Socket...What You Using?

I got all sorts of funky sockets but none fit. I see size 12mm, 12 point flange bolts mention on the Worlwide Web. Is that what I'm needing? And where'd you get yours?

Thanks!

I assume you are referencing a SBC.
If this is the case, the bolts are not metric they shouild be 3/8" NC. I have never seen metric bolts with English threads or English bolts with metric heads. Sockets come in 6 or 12-sided formats. I suspect 3/8" or 7/16" 12 point socket should work for you?

Should be 3/8 or 7/16 12 point depending on brand you can use a socket or a box end wrench. Now if they are on a later like 90 and up model v8 they could be metric

Re: Edelbrock Intake Bolt Socket...What You Using?

Those look sort of like the heads on bolts the Deere started using on tractors in the '70s. It's been awhile, but I seem to recall that 12-point sockets didn't work on them. Or maybe us old guys only had 6-point sockets? Memory is a fickle thing.

Re: Edelbrock Intake Bolt Socket...What You Using?

I just pulled an intake off a Pontiac that had those bolts installed. Cheap junk! They when straight from the engine to the scrap barrel. They were 5/16-18 threads

There was no consistent size for the heads. I ended up using a 3/8" six point for some and had to use a 10mm 12 point wrench for others and a six point socket to get the rest out. ABSOLUTE GARBAGE!

I’m sure it depends on the brand . Never have had a problem with ARP brand I use them on headers and intakes .

Seems to me I already went in there with those, that's really common. That's only one step up from a hammer and screw driver in any knuckle busters tool box...but I might of been trippin l'll look at them again...

There is such a thing as a reverse Torx. Maybe that's it?

Try 5/16 a picture of the actual bolt your dealing with would help

Re: Edelbrock Intake Bolt Socket...What You Using?

Those look like External Torx, aka "e-Torx" aka "external star" aka "E-sockets"(I wish I were joking)
I picked up a small set from Harbor Fraught because I needed them for a Jeep 4.0.
They're easy to find in most brands...once you figure out what to call them :-\

....Accelo beat me to it, I just didn't see their post

A long time ago I ordered a set of Summit-branded intake manifold bolts that were cheesy like that. But since then I've used nothing but ARP stainless bolts, both 12- and 6-point that take a 3/8" wrench. I recommend using the flat washers that come with the bolts.

I also use ARP's 6-point header bolts that are great for tight spaces where you can only use a open end wrench. They even sell a set with 5/16" hex heads.

Over the years, I've acquired a few ARP stainless bolts that I use for other applications like this:

Re: Edelbrock Intake Bolt Socket...What You Using?

What's a guy supposed to do, put a hitch on his tool box and take it with him in case there is a problem. My opinion is if you get them out bury them 6 feet under and go back to basics. I'm too old to change and I now know why a mechanic has 6 tool boxes. They are like my dad as he was a millwright and his spending on tools cost him the marriage. Sleep tight eh!
