quick question about screws

t0fler · Post by **t0fler** » Sat Dec 17, 2005 11:56 pm

I'm not really a noobie as far as portable consoles are concerned, as i have made a portable (after a fashion NES) however i thought the psone was a bit beyond me so ive gone and bought the book.

i took the list of screws and nuts to the local hardware store and the guy helping me didn't really understand what i was asking for.

I live in australia so i guess i was expecting a bit for him to work in inches, but he also didnt understand what was meant by size-4 screw size-6 washer etc,

could someone please clear this up for me,

thanks a lot

also dont you americans think it might be easier to say 4.75 mm rather then 3/16s of inch?

Generally any screw driver who's head is about 1cm (or about 3/8") acreoss should work. I dont understand the whole "I need the exact size phillips screw driver bit" the only time you'd need that is if your working with power tools of something specialised and the PSone is not any of these.

And for your questions about Metric vs Standard in understanding, we were raised using standard so to use metric is odd. And its esspecally annoying when a car has both these for its fittings and bolts/nuts.

what i am asking is what is the difference between the different screws that are asked for in the parts list. What is the difference between size 4 and size 6?

The honest true is not much. I've taken my PSone apart a couple times with just one screw driver. This isnt like with an Xbox where you need two or three bits.

i am not asking about the screw drivers

in the book there is a parts list

in it it says i need 6 size-4 screws that have a length of 1/4"

when i went to my local hardware store, the guy helping me took me to the screws and was unable to locate what i needed as he did not understand what i was asking for.

what i want to know is what exactly is meant by a size-4 screw
how large is its diameter, that sort of thing

The different screws (size 4, 6, etc) are standard sizes for machine screws under 1/4". I did a search for "screw sizes" to get the actual diameters of them and this is the first thing that came up: http://www.csgnetwork.com/screwinfo.html . It appears that the sizes for #000-#12 screws are in inches. Google is your friend

Sparkfist, please read the first post again. Not once did t0fler say anything about screwdrivers or bits; he was quite obviously asking about screw sizes. Just about everywhere but the U.S. uses metric sizes for diameter, length and thread pitch - no silly inch-based "number" systems where the numbers have no sensible correlation to the actual size of the fastener!

T0fler, a number 4 size screw is approximately 3mm diameter and a number 6 is about 3.5mm diameter. #8 is about 4mm, but #10 is about 5mm, and #12 about 5.5mm (the jump between 8 and 10 is mostly due to the inexact matchup between inch and metric sizes). You'll have to work out lengths, washers, thread pitch, etc. as needed. Odd-numbered screw sizes are rarely encountered (I assume the same for metric sizes like n.25 or n.75mm, yes?)

Anyway, the exact screw diameter isn't that important for a DIY project like this - just use what fits and is strong enough.

cheers AJ, one other question, does it really matter about the nylon spacers, are there other types, ive rang a few hardware stores and spoken to 2 big nut/bolt resellers who dont have any.

could i get away with something else?

thanks

I haven't read the book yet myself, so I don't know if Ben uses a manufactured product that snaps into circuit board holes, or if he's just using plastic tubing. Tubing type spacers can also be bought as pre-made nylon parts in specific lengths, but it might be just as easy to find any plastic tubing you can use and cut them yourself. I'm not sure who all the major electronics retailers in Australia are, but they would have the spacers. (Dick Smith, Jaycar, EA {Electronics Australia}, RS {Radio Spares}?) Do a web search if you don't know.

I ran into the same problem here trying to find #4 screws. I bought several different packs (at 84 yen each) and I think i ended up using the 2.5 or 3 mm ones.

You should be able to find nylon or plastic spacers at a hardware store, just make sure they fit whatever screws you get your paws on.
