Allen screw sets for points & points plate on the triples?

[Craig380]

Hi, anyone know the correct sizes for allen screws for the points and points plate on the triples? Or if there are any allen screw sets that can be bought off-the-shelf for these?

Thanks!

No! But I feel your pain!. I have a points plate here I'll check after a while. I just woke up
It took a while to figure out. Leave the phillips in the drawer. Using good fitting flat head drivers is the way to go.

I like Allen screws as well but in this case I got some Philips screws points and condenser screws with the lock and flat washers attached to them.
The biggest problem is people tend to over tighten them and damage the heads.
There are two different lengths of screws for the triples on the plate and of course you will need the washers, off the top of my head I think they are 4mm by 0.75 pitch.
I'm off to do some errands so Coyote may get back to you with the exact sizes before I return to check what they are.
You could also use button head Allens instead of the socket heads to make them look a bit more like stock Philips head screws.

Most are 4mm thread x 6mm long. I'm sure I got some from Toolstation or Screwfix.
Cheap as chips and lots of sizes.

Highly recommend getting some JIS screwdrivers.
Our vintage Suzukis have JIS screws. The slot profiles for JIS & phillips are similar but slightly different.

I have Vessel Megadora JIS screwdrivers & definitely recommend them.
Got mine at: http://www.levelchrome.com/VESSEL_bymfg_2-1-1.html
Sorry, don't know where to get them in the UK.

I keep mentioning the same point as jabcb (no pun intended ) - the screws are are JIS - most Phillips screw drivers will cam out JIS heads pretty quickly which is what we all see isn't it ?

You can usually get the screw sizes from the part number - I cover it on this web page. Length is sometimes in the part number also but not always. The contact breaker plates use 09125-05024, so 5mm - not sure of the length, but they are short. And the points themselves use a 02112-04067 so 4mm diameter and 6mm long.

[Alan H]

In the parts books that I have, it shows that on the 550s and 380s the points screws are 02111-04067 x 12 (for the J and K Kokusan points set), and 02111-04048 x 3, 02111-04067 x 1, 02111-04067 x 2, and 09125-05025 x 3 for all models with the Denso points set. So it looks like the 750s are different, but I don't have a parts book for them.
Stainless button head Allen studs are a much more sensible option in the UK weather, but tend to upset the purists, which is another good reason to fit them in my opinion!!
A small smear of copaslip will stop them seizing in future.

I just checked. ALL the screws on the points plate are 4mm diameter, 6mm length and all have a .70 pitch. I think that would be specified as M4x0.70x6. The 3 screws that attach the plate to the case are larger Probably 5mm diameter -- slots are not wide enough for a 6. Standard pitch on a 5mm screw is 0.8. Length unknown. See this cahrt:

If I was to change mine, I'd stick with the stock design (or a modern slotted head) as they do also have a slot for a blade screwdriver (agree with Ian that we've messed up most of them with poorly fitting cross head drivers!).
I like the blade screwdriver so that I can just slack it off a tad, use the same 'driver to move the plate or points and nip the screw back up again, all in one smooth operation. Bringing an allen head in means moving between at least two tools to adjust them. Just my 2c anyway.
Cheers,

+1 That's basically what I said in my first post in this thread.

This place is a treasure trove of fasteners, materials, fabrication stuff, etc.

No order too small. Super easy returns. I've never had to wait more than three days for something to arrive. Usually it next day if it comes from the warehouse nearest to me.

[Craig380]

Thanks for all the input, guys

The screws that are there were badly butchered by previous owners, I have managed to fix them a bit with gentle use of a drift but replacement's the best option

[Alan H]

If I was to change mine, I'd stick with the stock design (or a modern slotted head) do you have pics of people with slotted heads please?as they do also have a slot for a blade screwdriver (agree with Ian that we've messed up most of them with poorly fitting cross head drivers!).
I like the blade screwdriver so that I can just slack it off a tad Ooer mother!, use the same 'driver to move the plate or points and nip the screw back up again, can you say that legally nowadays? all in one smooth operation woo hoo!!!. Bringing an allen head in means moving between at least two tools to adjust them cough. Just my 2c anyway.

I'd love to know what you're on tonight Mike, but I have a ratchet screwdriver handle thingy and a set of about a gasquillion different bits from allen keys to every type of screwdriver bits know to man beast or anything in between (well, a lot anyway.)
I don't have a problem moving between two tools so long as they are both mine.
Try it Mike, you might like it.
Any problems, use a tissue to clean the implement between tools, so to speak - or t'other way round if necessary.

I think this thread should stop soon while it's still decent and legal.

You're missing the point (pun intended). While we are on this subject, does anyone know the size of the tiny nut that retains the assembly sandwich? I have found nothing that fits it, It does not appear to be metric or SAE. Even tried my distributor wrenches and tiny spanners. So, I have been using a teeny pair of channel locks. I'd rater not do that, but I can't find anything that fits.
Just checked. It measures 0.214. That would make it a 5.5mm. No gots 5.5 wrench

[Weirdbeard1000]

I know for a fact snap-on has 5.5 mm stuff. I have a deep and a shallow 1/4" drive socket. I would imagine Craftsman's has something as well. I bought the sockets for distributor cap screws. I can't remember now if it was ford or Chevy that used them.
