Will sell you a hundred of them at $0.62 each and laugh all the way
to the bank...


It isn't possible to laugh all the way to the bank unless the per unit
price is at least $4.00. That way, you can feel just like a
pharmaceutical company.

America got fucked by their fellow Americans. We just don't know it
yet.

Damn thing looks exactly like a standard screw for plastic boxes...
Without a size reference, i would guess a #4 ...

A #4 is a screw size designation for machine screws. That is a screw
made for plastic. Like a wood screw, it cuts its own threads as it is
driven in the hole the first time.

There is also a chance that it is a sheet metal screw, but it is
unlikely given the screw length, and the difference in the thread
construction is very small between sheet metal and wood or plastic
screws.

Being a "modern" Sony part, I would say that it is minimum Phillips
head, but could also be hex or thorax. It could even be torx with a
security option, which would also make it a "special crew".

That price is because it meets ROHS perhaps?


It mentions VAT charges, so it is likely what happens when one orders a
part from the US, through a UK vendor.

Though I do not know anywhere that it would be considered reasonable
markup. I can't imagine that anyone actually paid that much for one or
that one.

Or maybe that was an ebay final bid result!

Yes. Technically, the machine screws would be called "4-40" for the
same size family, in the US.

I believe the #4 refers to the diameter in 1/16's, the - 10 is length
in 1/8's

Wrong and wrong, and you also do not know about posting protocols.

The screw standard is not a multiple of 16ths of an inch, and the length
is not referred to in 8ths of an inch.


This ain't email. Refrain from top posting in Usenet. Learning about
and subsequently following the conventions of the forum you are
participating in is not difficult.

It definitely has a Phillips head,

No. It appears as if it could be a Phillips head. It could also be a
torx head or torx+security.
and i stated #4 to give an idea as
to compariable size;

Which it is.
i do not know what the designation might be for a
screw made for plastic.

I know there are differences in the thread and root height and depth
between wood, plastic, and sheet metal screws, which would otherwise all
be the same for any given diameter,
That being said, it is a common screw.

Not necessarily. Again, it very well could be a "security fastener".

They were commonly used in the video game industry days, and still are
in the electronics industry on any cabinet/can/chassis/etc. that they
want to restrict access to with a bit more fervor than a standard screw.

I am sorry if you are unaware of their existence. That doesn't change
the fact that they do exist. That does not make this screw worth 61
euros though.

It doesn't. The series starts at #0, with a basic major diameter of
0.060", and every numerical step above that increases the diameter by
0.013":


SIZE BASIC DIAMETER
-----|---------------
0 0.060"
1 0.073"
2 0.086"
3 0.099"
4 0.112"
5 0.125"
6 0.138"
7 0.151"
8 0.164"
9 0.177"
10 0.190"

Note that there is no ANSI/ASME #7 or #9, but the diameter changes as
if there were.

Interesting. I use #7x1-5/8" square-head-recessed stainless trim
screws all the time.

I don't ever remember seeing _any_ of the odd-numbered screw sizes.

...Jim Thompson

Given your lack of an eye for the details, I doubt seriously that you
could identify a screw by sight, so you wouldn't even know if you had
ever seen or used them.

I wasn't doubting you, just that the "size" does exist. ...and the
screws *do* exist (I've even bought them at the "local" hardware
store). I'm pretty sure I've seen #5s too, though can't remember
where.
