RE: [DML] Re: Rusty Exhaust Manifold Studs

["PJ Grady" <rob@xxxxxxxxxxx>]

Hi Bill,

Not anymore! If you want a set of HARDENED STAINLESS 7MM exhaust studs I
have a box of them on my office floor awaiting further inspection. These
beauties are custom made for us and are stronger than the stock studs yet
can still be drilled out should one ever fail. Cost will be similar to OEM's
because we made a lot of them. I am now researching the best nut and washer
combination to use with them. Any comments from the "peanut gallery":).
Qualified suggestions would be most appreciated because I've received
conflicting advice over the years about stainless on stainless, brass on
stainless, steel on stainless etc.

Stock exhaust manifold studs are M7x1 -- rather uncommon in carbon
steel, impossible to find in stainless steel. Those same holes will
tap extremely easily to 5/16x24 (24 TPI is almost identical to 1mm
pitch) -- very common in stainless. Tap will thread in as easily as a
bolt, which is useful for the studs on cylinders 1 and 4 hidden behind
the crossmember. Replacing carbon studs with stainless steel would
make future removal problem free. Don't forget the studs that hold the
manifolds to the crossover pipe (M10x1.5 -- also common in stainless).
