Body Bolts Question

[Aguyandaredhead]

Hey guys, I was wondering if anyone out there could take a few bolt measurments for me? My car has been in paint jail for the last 18months and he tells me that it is jammed and ready to hang the sheetmetal back on so he can now spray the rest of the car. One of the things I wanted to do was replace some of the body bolts with something slightly different but the same thread size and pitch (only change the head style like panhead torx and cap head allen's) but I have the original bolts in storage and the car is 2 hrs away for me to go check the jamb nuts for size and pitch. Below is a list of the ones I need to get, if possible could someone with a tap and die set or a caliper and thread pitch gage check them for me? I have looked all over the internet with no luck at this point. I know I could buy the zcreations stainless kit but that is not what I am really after. I have a stellar Nut and Bolt place here in town and I would like to go pick them up asap..

Fender to Body under hood bolts?

Fender to Body where the Fender bolts to the rocker on the bottom?

Fender to Body inside Door Jam?

Fender to Cowl area under Cowl?

Fender to Headlight extension of Body?

Headlight bucket to Headlight extension of Body?

Hood to Hinge?

Hood Hinge to Body?

Size (not hex head size), Length and thread pitch...

I know that sounds like a long list but someone has to have them handy and be able to check them. Thanks in advance..

Dang, 65 views and no love yet...Is it that difficult of task?

I think it might be...

A whole bunch of issues with your request.

First: What model car???? I assume an S30 with headlight buckets...but details man, details..

Second: You're looking at relatively few people that might be able to answer. I've got a lot of tools, but no tap and die set (probably should have that...). I certainly don't have those bolts off the car... You need a combination of the 2...pretty rare...

All the looks are because we tend to want to help...this may be a challenge...

Did you check the FSM's at carfiche.com? Might be in there?

I think Michael hit it on the head. I've got the tap and die set, but no longer have a disassembled car to use them on.

I actually have some of these bolts in bags, I took a look and it seems mine have been replaced over the years with generic 'whatever fits' bolts because in my baggies I have a bunch of different bolts. Most of them are not the zinc colored ones I assume to be original. I dont have calipers or a thread pitch gauge either.

You also need someone who has all their original sized bolts too! I used the microfiche cd to find out the size of bolts I needed for most of the front timing cover, maybe that will help you. Do you have the microfiche cd?

According to his public profile it's a 1972 240Z...

Well I understand your statment about detail's, however I would have figured since I posted this in the S30-Body and Paint forum that would explain what car (since these bolts are all the same on 240/260/280). I realize not everyone has all the specialty tools but I felt these were somewhat standard for someone doing a resto, I can't be the only one doing a complete tear down.

I will try the FSM option, I looked for the information on the Nissan parts site but had no luck.

Thanks for posting it is a 72' 240 from my profile by the way, just incase there was q question.

Still looking for the info.

Fastenal have nifty little tread pitch/size measuring tools. Kind of like a rectangle ruler about 10"x3-4". They will give them to you for free. Kind of like this one. It has the thread pitch on one side. You just lay the bolt on it until you find the pitch that matches

The majority of your body bolts are the 10 mm hex heads. That equates to a 6mm shank on the bolt. Thread pitch is usually a 1.0. I have a tap & die set and all the bolts you're asking about sitting in the garage. I'll do a quick check for you and get the data. The FAstenal store here in Fairbanks has a Z fanatic as the General Manager. I met him yesterday. He's not on here for some reason, but probably will be soon. Let me see what I can dig up for ya.

TRYKFLYR, That would be very helpfull.. I had thought most of them were 6mm 1.0 but want to be sure since the type of replacements I am buying are not easy to find and somewhat expensive as bolts go.

I do think the ones on the lower rear part of the fender to body are 8mm but I am not sure if they are 1.0 or 1.25 thread pitch.

If you can confirm for me you would save me countless gallons of fuel to make a trip to check them for myself. I would really appreciate it.

Thanks

Here ya go. The 10 mm hex heads are m6-1.0 the 12mm heads are m10-1.50. That should cover all the hardware for the fenders. Fastenal has the internal wrenching cap screws you're looking for in stainless. Make sure you clean the area around the boltholes and the weldnuts real well. Dissimilar metals, a little dirt, add some water and you basically have a battery. It'll corrode on you. Use a thread lube on the satinless bolts too. A little beeswax on the threads before you start the bolt works well. You can get it at any sewing or hobby shop. Boeing puts out this stuff called BoLube for drill bits. That works great too. The parts/pilot shop at the airport will carry it. A little goes a long way on these.

Just curious. Are you going to opt for stainless bolts?
