One the original PDP-8 ("Straight 8"), the front panel
has two aluminum
strips on the sides, one on the left and one on the
right. Each should have
a pair of flathead countersunk screws, likwly Phillips
head.
Can someone tell me the exact specs, basically thread,
length, head, and
material of the screws?
I have no idea what the straight eight screws are, but for
comparison the sort of screws in
the PDP-11/05 are things like #6-32 x 1/2 phillips pan
head, #10-32 x 5/16 phillips head truss,
#8-32 x 3/8 phillips pan head nyloc, #2-56 x 1/2 phillips
pan head, #4-40 x 3/8 phillips head
flat. And so on it goes.
I read somewhere DEC used a lot of stainless screws but
that may not apply to all of them.
Certainly the cheese head screws that the 11/15's 10-1/2"
chassis pivots on are stainless, I
checked that for curiosity's sake when I machined some
special adapter washers to use with
modern server slides.
At any rate, you have that wondrous (but US only) fastener
supplier's website to help you out.
Steve.
I have four straight-8 panels. All have flat head, stainless
(at least non-magnetic) screws. Three have Philips head screws
and one has slotted head screws. All are 0.38" total length
with about 0.28" thread length. Looks to be an 82 degree
countersink.

I just noticed the three Philips head panels have the plastic
front, my only glass front has the slotted screws.
