Im Dumb, what bolts for my bull bar?

[taslucas]

Yep Im dumb. I left my old bolts out at my parents house. Im going to buy some nice new shiny ones but what type? Is it M16 or something? im dumb about this stuff. I plan to buy the toughest ones i can afford.
I will go get them as soon as i get a serious answer out of one of you (which will be a while knowing you lot! Growlers, Scotty, Winnie, Clunk, Nisshead, Georgina need not reply!!):tease:

[Alitis007]

Well Lucy if you had a GU i'd say 110% they would be M14x 1.5 zinc coated high tensile bolts with flat and spring washers, the length should be about 30 - 35mm.

They look like this

High tensile steel is 8.8 t the normal is 7 i think. Normally they're black steel but the zinc coated ones are silver so they don't rust as fast. Stainless would be better coz they're a bit stronger but will cause electrolysis (rust). But when you go to the bolt shop ask to try it in the chassis first to make sure you've got the right thread pitch!

I forgot your not driving it daily anymore lol just go grab an original from you parents place or use one off the front recovery point to see if they are the same, i think they should be.

Cant be bothered driving out to the pairs place lol its a bit of a drive

[threedogs]

Only use Zinc plated bolts, you can get better than grade 8, but grade 8 is fine IMO, Could use H/T washers,.
1.5 only means metric coarse thread. Did you require any nuts??

All 6 holes have captive nuts. I just went to the local Mitre10 they only have up to M12 lol but they do sell toasters and kettles now! Ill get a single bolt and double check the thread on the captive nuts.

[Alitis007]

You'll have to go to a bolt shop Lucas coz all the mitre 10 and bunnings only stock m12mm bolts. You could always invite the ol folks over for dinner and ask them to bring the bolts with them ?? Lol

Might want to smear some copper coat or never seize on the thread,

[BigRAWesty]

I actually have 2 types of bolts.. 14mm metric fine and them a UNF of similar size.. only found out when i went to reinstall the bar and the basterds wouldn't do up...
So take it to a bolt joint, blackwoods etc and get them to try a couple before buying. Just in case yours is like mine..

Fyi, ill be changing all mine to metric fine when the new bar goes on..

Not looking for an argument, but don't use use ordinary stainless bolts, as they are actually weaker than mild steel bolts.

I actualy thought that but i then thought i must have been wrong lol. Stainless is more brittle

[BigRAWesty]

Stainless is infact softer than mild steel..
Its the compound of which its made that makes it feel stiffer and heavier.
Once stainless is heated and cooled it becomes more brittle. That's why you have to be careful not to work harden stainless when drilling.. slow and steady and lots of fluid..

can i suggest you go for GR8.8 galvanized bolts , these have a coating of around 50 microns of zinc, the zinc bolts only have about 5 microns and will rust quicly when exposed to the elements

[taslucas]

got an m14 - 1.5 bolt today to test the captive nuts in the bar. No go, its too thick. The bar looks like and ARB but im not %100 sure. Would all ARB bars have the same size bolts?

[Clunk]

thread pitch to big or the diameter of the bolt?

[taslucas]

bolt too thick. thread looks like it may be the same......

I reckon you'll be the same as me.. try it in all the captive nuts first..

OMG this is gonna be a long saga! Right im gonna call on a few mates to bring a handful of bolts around and try to find the right size

[threedogs]

14mmx1.5 is the same thread as a spark plug, 5/8 is = to 16mm from memory. stretching this out Lucas.
I would have gone 14x1.25 which is the fine metric, happy to be wrong as meds running low
for cost ARB may have used imperial bolts as metric bolts can sometimes be very costly.
having said that IMO I would think ARB use all metric hardware

[Alitis007]

Strange its not a 14mm bolt, next size down is M12 or a 1/2" but being a jap car see it being imperial unless some one has mucked around with it and tapped a new thread??

Right! Would of thought the bolts would have been on the chassis ?? But if you can get your hands on some verniers to measure the size of the hole and the depth of the nut, thickness of the chassis rail and add 10mm that will give you the thickness and length of the bolt.

Going by whats in front of me you have 4 captive nuts and another 4 that need their own nuts.

Get one bolt to try if its all good you will need


8 x spring washers
12 x flat washers ( which need to have an out side diameter of 35mm )
4 x nuts
8 x bolts

To make things a little harder fr you the bolts on the left side will probably be different than the ones on the right. They are on both my GQs.

[taslucas]

Nah it's a different set up altogether. The bullbar slides inside the chassis rails. It has three captive nuts per side. When the bullbar is slid in, the nuts line up perfect with holes in the chassis rail. The six nuts appear to be the same. I'll get some pics after work.

Got a bolt off a mate that screwed into the nut but wouldn't go all the way through so the thread was slightly different. Went to bolt shop today and showed them the bolt they said it was 1.75 thread, gave me some with 1.5 thread and the damn things won't screw in as far as the 1.75 I had?

FanTapstic!

[Ben-e-boy]

Go to the local hardware and get yourself some thread gauges. They are like feeler gauges but with thread pitches etc. get metric and imperial to be safe. Then all your problems will be solved :) except for that rash. Lol

[threedogs]

Is he saying they are metric ???

[nissannewby]

Wouldn't go all the way through the nut or only would get one turn into the thread?

If it goes pretty much all the way through then there won't be much wrong with the size. The nut might be slightly damaged.

[taslucas]

yeah i just thought it would have been a lot easier than that. Its got to be such a common size. Annoyed that i had a bolt that was %99 percent right but now im further away!

most common would be 1/2" unc, thread looks nice and coarse

[nissannewby]

Possibly try a 1/2" unc but if you can get it that far through that would be the one I use. If its an M12 we are talking about it would also feel a little sloppy in the thread if the nut was unc

Only metric will fit these beasts. Guessing its 1.25 thread. Like the majority of everything else on the 4bie.

The captive nuts arent part of the vehicle though. They are part of the the bullbar and i cant tell if they are ment to be like that or if they have been added later by someone else. (the bar looks like an arb but has been modified before i got it.)

1.25 would be lucky to go one turn into a course thread.

What did i say yesterday, 12" unc 13. I got it from BA's bar which is an ARB bar........

Ahh bugga. No idea then. Only proper way to know is to either have lots of bolts on hand or use the guage to measure the thread.

What size are the nuts welded to the bar like socket size? If - 3/4 or 19mm spanner is the go for them then the bolt will be half

Ok, the top bolt is the one that nearly fits(goes nearly all the way through the captive nut). It has CM 8.8 on it.

It looks as though they are not nylock or lock nuts so its is possible they are 1/2" bolts.

[Parksy]

If one of those bolts goes in 3/4 of the way in, it's more than likely the correct one. If its the wrong thread, it will stop at the 1st or 2nd thread and won't go in further. Does it go in that far using finger pressure, or do u need to use a spanner or socket to get it in?

[taslucas]

Goes in that far with finger pressure but it stops in exactly the same spot for all six nuts.

Might be BSW thread , only reason aftermarket use imperial is cost, 1/2UNC x 2" could be 40 cents
where as a 12mm 1.25 pitch x 50 are $1.07 each. I know cause I buy by the box all the time.
I'll ring my bolt place this morning for you and see what they think.

[threedogs]

bumped. @ Lucas, rang my bolt place and came up with this , Its like I said more than likely its BSW, thread which is 12 TPI [teeth per inch] instead of 1/2" UNC which is 13 TPI.
One interesting point he made was that BSW bolts don't come in HI tensile. I'd buy a 1/2" UNC tap and re tap it so H/T bolts can be used

email sent to Lucas

[Parksy]

A quick search on google found someone using m12 1.25 thread pitch.

[threedogs]

@ Parksy thats metric fine, my money is on 1/2" BSW.
a lot of after market trade use BSW and in weird sizes like 9/16th bsw
I'd either one re tap it or cut nut off and use correct thread pitch.

Why is that mate? Isn't it a 1/2"UNC ??

[taslucas]

havent tried the 1/2" unc yet. The bar had been modified for a winch and a 2" body lift and i havent seen any arb bars with the same captive nut setup (im still only guessing its an arb bar) and the weld jobs on the nuts look a little home made but im not sure how they'd look if done at arb. Gotta be close now though! ill swap my bolts for the unc ones. Bugger all open here saturday and nothing open sunday so monday it is!

[Alitis007]

I think Bunnings or mitre 10 should stock the 1/2" ones mate pretty sure they do actually but the cone in packs of 2 and black steel not zinc. If that bolt is still no good mate i suggest you take the whole bar to a bolt shop and get them to measure it.

Throw up a pic of the weld ?

[taslucas]

Lol yeah i went to mitre10 but i wasnt looking for the 1/2 unc so they may have those. Closest bunnings is an hour and a half away:). Do ya reckon zinc is better than the black steel?

Yeh the black steel will rust fast and seize and i'm not sure if they are high tensile or not, so they're 7t not 8.8t.

More than happy to post bolts , this pic is to tease

[taslucas]

your just a pic tease!

[taslucas]

Well, i got a few 1/2" unc today and just tried them then. They do up nicely with fingers but get to that last two or three turns to go and bind up. Its exactly the same on all six nuts. And the 1/2" unc go in the same amount and feel exactly the same as the metric 1.75 that i had??? is that weird?
Could it be that the last time it was mounted it was slighlty cross threaded but the bolts werent long enough to go all the way through the nut. OR they have vibrated around a bit and wrecked the thread? It doesnt look that way to me but i dont really know how to tell.

[Winnie]

Are the bolts painted? I had this trouble once and it was just paint or something on the bolts so did them up with a spanner and all was good.

If you're happy and you know it tap a post!

[taslucas]

Nah ive just had a better look and it appears the thread inside the nuts is flogged out. Maybe the bolts werent done up tight enough in the past letting them move and vibrate around and flog out the thread?

Ok so a 19mm spanner fits perfectly (snuggly, no movement at all) onto the nut. That means it i should use the metric bolts i got? Whack em in and crank them past the last two rows of thread that are the problem?

[threedogs]

19mm =3/4" same thing fits 1/2" UNC head

And I only got hold of some UNC bolts today and to my surprise they fit the same as the metric ones I got. So after a closer look I reckon the thread is flogged out, but flogged out the same on all 6 nuts.
1/2" UNC it is and just crank em through the last two rounds if thread with a spring washer to help keep it tight

FanTapstic!

Throw some sort of lube on them too Lucas. If you don't have anti seize you can use grease or oil.

High tensile steel is 8.8 t the normal is 7 i think. Normally they're black steel but the zinc coated ones are silver so they don't rust as fast. Stainless would be better coz they're a bit stronger but will cause electrolysis (rust). But when you go to the bolt shop ask to try it in the chassis first to make sure you've got the right thread pitch!

I like the word 'bolt shop'. :thumbup::)
