metric socket mystery???

[sickboy motors inc.]

so the other day I'm putting all of my loosie sockets on rails that I just bought and noticed I have a few of the 5.5 millimeter sockets. the question is what in the hell are they used for? I can't think of 1 time that I've ever used a socket that small in metric. so who out there knows the answer to this question

I've seen a nut that small within the last month, but I can't remember what for. It was extremely small though

Ford distributor modules is one I know of.

GM uses them everywhere. Coil packs are the most common

Remove ac blower motor on Toyota/Lexus vehicles, maybe other imports as well not too sure. Comes in real handy.

I used 5.5 yesterday to replace the wires on the contact breaker points on my Suzuki motorcycle.

GM ignition coils mounted on the module. Holden Commodores down here.

^^ this ^^

I was going to say motorcycle electrical and carbs, and its fun when you go to the hardware store to get the oddest sizes you can, especially since Fastenal quit making bolts with 9mm heads lol.

Cam positioning sensor for the 90s 5.0 Ford. Kinda surprised me when I was working on a Mercury Mountaineer and this oddball socket was just the ticket...and I had 4 of them. Only time I ever used it!

Euro Hose clamps ("ZEBRA") in the small fuel line sizes use 5.5mm

 

[scottydosnntkno]

Headlight retainer screws on a ford super duty(06). Grill retainer screws. Fender retainer screws.

Bunch of other places too

 

[Hetman]

Standard size for M3 nuts and bolts.

 

[AZ_Catskinner]

Yamaha outboards are full of them.

 

[Dave.R]

I can recall using them on sensors. Pretty commonly.

The one that really gets you, is the 4.5 mm

 

[BFBOB]

You'll also run across them (and it's smaller brother the 4.5mm) if you cannibalize copiers, printers, etc to get those neat gearmotors, magnetic clutches, gears, sprockets, etc. I did that and built a nice power cross slide drive for my Buffalo 9x20 lathe.

5.5mm screw is actually a SAE 7/32". You can find that socket from almost any 1/4" dr SAE set.

 

[toolmutt]

Just last week I loaned a 5.5 mm nutdriver to the repair technician who was replacing the electronic on/off switch on one of our hydraulic rescue spreaders.

 

[rusty65]

Isuzu 4 cylinder motor can't remember where though

 

[Murphy4570]

Ford uses them on underbody plastic trim pieces on newer cars. Very common size for that.

As stated, they also used them on their TFI modules on distributors, back in the '80s-'90's.

 

[lbgradwell]

5.5mm screw is actually a SAE 7/32". You can find that socket from almost any 1/4" dr SAE set.

7/32" = 5.55625mm

 

[crewchief888]

dist cab screws on GM 4.3tbi

 

[96snma]

Replaced all the dash lights in my silverado. Full of them in there as well as my gf honda dash

 

[Jarhead0408]

X3 on the Ford distributor module's. Used mine on my '87 and '88 Rangers.
A few other things as well but I can't remember what right this second.

 

[Toolhorder]

Saturn used 5.5mm for the column trim cover screws.

Never seen one in a Honda dash. All bolts are 8mm/10mm usually.

 

[goodspeed]

Mine go down to 4mm. Never used a 4mm. Probably never will, but what the hell. I have it, so it's going on the rail.

 

[parrot head]

i had to get one to change dist rotor on 2.8 in a 85 s10.

 

[KinzeMech]

I have a few of the 5.5 millimeter sockets. the question is what in the hell are they used for?

I can't believe no one gave the obvious answer on the first page.

For bolts/nuts with 5.5mm heads!!

Seriously though, I've wondered, kind of along the same lines, why several of my SAE wrench sets that increment on the 1/16", always have an 11/32. As much as I'm curious, I know, all I really have to do is take it out of the toolbox. Then I'll roll up on the job where I need it, TOMORROW.

 

[Sparkfarmer]

We use them for the nuts that go on M3 threaded stand-offs for stacking circuit boards together.

heater boxes on fords,chevys and chryslers.
