Hex key IM bolts

[hunker7]

Manifold is coming of soon, and I'd like you replace IM bolts with hex bolts? Any suggestions where to get good quality ones?

Any decent fastener supplier should be able to sort you out. I don't know what size you need but grade 12.9 certainly won't break!

Thanks. EBay cheap stuff can be used for certain things, but this ain't one of them. I'll check sizes on vagcat and order some.

I use A2 stainless and they work a treat.

A2-80 is a higher tensile stainless close to 8.8

WHATTT? You want to replace the Allen head bolts with hex head bolts? Good luck with installing the IM.

Access to many (6 of 10?) of the intake manifold bolts is restrictive as it is. Never work with a conventional hex head bolt and a socket on an extension. No access.

You just need this:

For clarification, I meant to say I use A2 stainless allen head bolts, certainly not standard hex head bolts. Allen heads are easy to locate onto and you can use a ball head allen key to provide more angle to get at the head of each bolt.

Thanks for information guys.

Dave, I am not replacing head bolts but manifold bolts.

I know. The term "Allen head" does not mean "head" bolts. It is a common term for the the internal hexagon socket-head bolts, probably invented by a Mr. Allen.

Also know as Socket-heat cap screws:

"Socket caps have a small cylindrical head with tall vertical sides. Allen (hex socket) drive is a six-sided recess for use with an allen wrench (hex key)."
