OK, let's find out who the real sickos are.....

Where are the naturally occuring odd-sized bolts or nuts on a Z? (that's 7-9-11-13-15mm and so on...)

The only one that I recall off the top of my head is the 27mm bolt that mounts the Crankshaft Dampner to the Crankshaft.

Oh, there are some 17mm ones (somewhere), but at the moment, I can't remember where they are. (outer spindle pins??)

I'll check around on Weds or Thurs when I am under the car next.

Choke & Throttle Pull Screws---really odd size and I STILL can't tell you what it is.

The nuts holding the instrument gauge inner workings to the housing. 4 or 6mm

The Heater Control Panel Mounting Screws. Not only are they of an odd size, but their pitch is different as well. 4mm 1.25 (it's odd at that size)

more to come.....

While these may be "unusual" sized, they are still "EVEN" sized.

Zvoiture · July 1, 2003

Yes, I meant simply 'odd-number-of-MM-sized'....

As in: Tranny crossmember bolts: 17mm

Another question:

What part of your zed is made of steel, aluminium, and held together with stainless steel bolts?

Mr Camouflage · July 2, 2003

p.s. Its's also held together in some places with rivets.

MikeW · July 2, 2003

I recall having 13mm exhaust manifold nuts but 12mm intake manifold nuts. Of course - they might not have been original.

The grille?

The bolts that hold in the seatbelt latch are 11mm, fine thread.

I went to midwest fastener co, a 20,000 square foot warehouse of nothing but nuts and bolts.

They didn't have any.

I bought a 12 mm fine thread tap and a bolt at the hardware store. Since I was tapping out the original hole, I got longer bolts and used a washer and nut to make sure my seatbelt stays put.

But what size wrench did you need to use for the bolts?

I think that is what we are talking about here.

FWIW, check out Lawson Products next time you need bolts or nuts. I've ordered bolts and nuts from them that have the correct hex head size (even MM sized, i.e. 10, 12, 14mm etc.) and they seem to have many if not all thread pitch variations available as well.

Bambikiller240 · July 3, 2003

19mm Wrench required for these.

mdbrandy · July 3, 2003

Tiny screws that hold the fuel and brake line clamps are 7mm. Rubber brake/clutch line fittings are 17mm. One of the Rocker pivot nuts is 17mm (the other is 14mm, I think).

Weird bolt on drivers side engine under the manifold. 19 or 21mm, don't remember. Manifold nuts are square require monkey wrench and vice-grips.

hmsports · July 3, 2003

Aren't we all odd nuts?

Not on any of the 3 - 240Z's that I've owned. The 3 nuts that mount the down pipe to the exhaust manifold flange have been 14mm stainless steel hex nuts, and the nuts and bolts that attach the intake and exhaust manifolds to the cylinder head have been 12mm hex nuts/bolts.

Per Z Car Microfiche CD:

Nuts (manifolds to head) = p/n 08911-10810 Nut - Hex

Nuts (Ex Manifold to Downpipe) = p/n 20600-87100 Nut, Fixing; Tube End (these are Stainless Steel Hex nuts)

Zvoiture · July 4, 2003

Yeah, I have never seen square nuts either in that location--or any, for that matter.

Yep thats the right answer.

I've had mine in pieces, stripped it and repainted it. Now I just have to put it back together.

Whew, your silence of the past few days had me worried. I was under the car for several hours yesterday and searched high and low for something else that fit the specs you had posted and the grille was the only thing I could find that had rivits, steel, aluminium, and stainless bolts.

So,, is my "prize" in the mail?

Throughout the entire car . . . mainly the body and interior. I just stripped another Z down recently (a 240 this time), and had sockets scattered everywhere. :cross-eye

Found some. In taking apart my dash last night, I removed the brackets that hold each of the three instruments (clock, oil, etc.). The bolts that connect the brackets to the dash (not the gauges to the brackets) go into sliding, trapped nuts for adjustment. And those nuts are square! Don't know if this counts or not since you don't actually have to turn the nuts, but they sure are square!

Zvoiture · July 11, 2003

>>>>The bolts that connect the brackets to the dash (not the gauges to the brackets) go into sliding, trapped nuts for adjustment.<<<<<

Oh yeah, you're right...and also the front valance/fender connection is square nuts trapped in sliding boxes....

So what's the official term for this 'capturing'? Is htere a different term than nuts that are 'captured' by spotwelding?

there are also three (3) square nuts held in place for the rear license plate light assembly, not sure if it counts but they are there.

and my replacement small hose clamps are 1/4" or 7mm?

it's to early for me to think this hard:stupid:
