Does anyone know the proper stop lamp/parking lamp lens
screw for the S1 4.2 E-type? A quick search on the forum
did not help. The JCNA Series 1 E-type Judge’s Guide says
‘‘slotted’’ on page 14. However I have seen plenty of chrome
pozidriv screws on cars. I remember my '69 original S2 E-
Type had the pozidriv- and my S1 4.2 has them (pretty sure
they are original). I believe the 3.8 E-types had the
slotted, but I can’t find when they changed over to the
pozidriv. I just ordered a set from XK’s and they are the
pozidriv. I notice however, Barrett’s are slotted-
according to their catalogue. I bet this has come up
before. Anyone?–

Tom,
Most of the information on screws came from a highly respected
restorer in the Chicago area who has restored basically nothing but
XK’s and E’s for well over 30 years. Jim has kept a photo album on
some of the cars that he restored and when I presented this question
to him back in 2002 he looked through his records of cars that they
had worked on. He said that the two most notable were a 24,000 mile
1967 OTS that had been stored since 1980. They repainted left door and
both rear quarters. The other was a 67-1/2-30,000 miles car that
shouldn’t have been restored. Both of these cars had slotted screws.
At that time his supply of NOS parts were just about deleted but what
he had left was:
rear lens 54572373-10/64 slotted
rear lens 54572373- 9/61 slotted
side & flasher lamp 52789-10/64 slotted
side & flasher lamp 52518- 10/68 Phillips
side & flasher lamp 52788- 9/69 Phillips
rear lamp 53866- 2/80 Phillips
The above information points to Lucas using pozidriv screws after the
1967 MY. It’s interesting to note that Jim uses the term Phillips
instead of pozidriv, as many of us did at that time, and Jaguar used
the term Phillips in Spares Bulletin P115 to describe the new
headlight rim screws.

Tom,
I do not understand the screw sizes specified.
A #10-32 is .190 inches diameter, a #8-32 is .164 diameter. The problem I had was that most screw heads are too large a doiameter to fit into the plastic counterbore,. I bought several boxes of #10-32 filister head stainless screws from Grainger or McMaster and that is what I used for the rear.

Thanks for the information. It seems logical that they
changed the screw type at the same time the lens changed
from the SI to SII.–

It’s terrific that such detailed observations are available, really!
And while researching my 69 E-Type for originality I also learned that
sometimes, it was a simple as “use what was available in the bin.”
It’s what makes it fun.

If I could take a guess… #10-32 is an American way of
sizing screws
Lucas, at least in the models I work with used BA threads
Some of these sizes are very close to the US style
So for example the Jaguar 2 BA thread commonly used on trim
items is very close to 10-32.
Some of the screws were made specially for the part used .
Two weeks ago I had a batch of screws NC machined for the
SS1/ SS100 owls eye Lucas tail lamp
These were 2 BA but because the head was larger than a
standard 2 BA head they had to be machined from brass stock.
I have occasionally cheated and replaced BA screws with US
screws because they were available in stainless steel in a
size close to BA, in SS100 windscreen pillars.
However these had heads that were too large and I solved it
by put each screw in the lathe and turning the countersunk
side of the head back until the head matched the original BA
head size.
I certainly remember my series 1 E type at the time having
straight slotted screws on the headlamp rims as I had to
replace some with longer ones to accommodate a bra for the
bonnet.
It may be easier to start with the original UK screw size
nomenclature.–

That’s probably why I ended up “cleaning up the threads” with a 10-32 tap.On Mar 2, 2014, at 3:28 AM, Ed Nantes enantes@bigpond.com wrote:

3.8’s were slotted and 4.2 were posidriv (Philips).

‘‘Part number 8606 ‘Screw, securing lens’. On the 3.8 cars these
side/indicator lens screws should be slot head and not the

have a small lead in nipple at the start of the thread, which is
peculiar to Lucas.’’
On that same forum S1 Factory Fit section are posted photographs of
several origional unrestored S1 cars with very low miles. The 1961,
875103 clearly shows phillips. 1963, 88730 and 1966/67, 1E13256
both show slotted.
Is it accurate to say that for the SI E-Type that either slotted or
phillips head screws were used on the stop lamp/side lamp lens?

Tom.
The parking light/stop light screw appears in all of the Jaguar E-
Type Catalouge’s, J30,J37 & J38, as the same part number 8606. The
lens, surround, screws etc were a Lucas supplied assembly and Jaguars
main input was the the color of the lens required by the various
countries where the cars were being dispatched . At the time that
research was being done on the original version of the S1 judging
guide, besides personally looking at a few original owner unrestored
cars, one long time E-Type restorer still had some Lucas side light/
stop light assemblies in the original dated Lucas boxes and none dated
before 1968 had the posi drive screws. I learned long ago that photos,
period factory photos excluded, unless you know the owner and the cars
history means very little in proving authenticity. Not that it’s proof
of anything but since the guide was approved in 2003 , and as I
recall, available for comments through JCNA in 2002 this is the first
time the accuracy of this area has been questioned.
We, myself and JCNA, are always open to new information, especially
concerning authenticity, so if you have anything to share please
contact me by email or contact me with a phone number and we’ll talk
if you’re in this country.
