See Phils comment!
My mistake - of course the C4202/2 nuts are ordinary plain steel 5/16"UNF
hex nuts - but as they are CADMIUM Plated they get a non-standard part
number(Sorry - not bronze/brass as per exhaust nuts)!
I should have checked my part number spread sheet for non-standard fasteners
as per a Cxxxx part number -
And no - there is no listing of “non-standard” fasteners such as Studs (with
different threads each end) and hex nuts (that have been plated) - this is
something I have built up over the years as an ongoing work in progress.
“Standard” fasteners - such as the FG105/X spring washer are listed in back
of a few of the earlier Spare Parts Catalogues - such as XK120, Mark V, Mark
IV - but this useful guide was dropped from later SPCs.
A “Standard” fastener is one made in accordance with the relevant British
Standard.

Roger,
Thank you for the information, is there a source that I can use to look up a
part number to cross reference sizing for the various studs, set screws, nut
and washes for a 150? I would prefer not to bother the list requesting
information I should be able to find myself.

Chris,
The C11761 stud is 5/16" diameter with a 5/16"UNC thread on the end that
screws into the cylinder head and a 5/16"UNF thread on the manifold end
for
the securing nut.
A C4202/2 is a standard 5/16" UNF hexagon nut, but made out of BRONZE,
albeit modern replacements are more a BRASS than BRONZE.
An FG105/X is a single-coil square section 5/16" SPRING WASHER

Is anyone be able to tell me the diameter, and thread sizes
for:
C11761 Stud, in Cylinder Head, for fixing of Inlet Manifold.
Also need size and type of:
C4202/2 Nut, on Inlet Manifold Studs
And last but not least:
FG 105/X Washer, Spring, under Nuts
Alternatively is anyone able to direct me to where I can
find this information. I have the CD with the Parts, Panels
and Fittings, but the section on Standard Fasteners does not
cover studs, nor does it provide dimensions.
Thank you
