Cas Bolt Sizes And Thread Pitch?

[75coupe]

I have a few tap and die sets but the 3 CAS bolts seemed to be something different to what is common in the engine bay and also outside of what i have tap, bolt thread wise. Anyone got the specs on the bolts?

[abr33]

Without checking im near positive they are the ever common m6 x 1mm pitch

[blind_elk]

I reckon they are 6x1.0 - I have that tap / die combo in my set.

they dont fit my M6x1 tap, someone want to confirm Im not martian...

Get new ones off Nissan? They'll be $3 each.

Thats literally 20 times more than they are worth

I dont want new factory ones, i want to know the specs so i use better ones..

[75coupe]

Wait before anyone says 'nissan spent time working out what was best' the factory ones are fine, great even!

But i want prettier ones that do the same job, hows that?

its 100% m6x1.00

if tap doesnt fit then threads are prob stripped. drill and helicoil

[75coupe]

Hmm ok cool, ill triple check with my martian friends

[75coupe]

Thats the cas bolt against a m6x1 tap...??

[75coupe]

Maybe the tap aint 1.0??? Damn martian frost tools

[abr33]

Yeah its definately m6x1 and get some s/s allen head bolts :-) they are the prettys

Unless yours was once stripped and drilled and tapped to something else?

It doesnt look like but.

[75coupe]

Yep im putting together a complete allen style stainless kit for r33. Maybe the beer was altering my judgement... Should be a good kit though

Measure again

Looks pretty cool

Ok sorry to keep on this but ive confirmed my m6x1 tap does not fit thread wise to the rb25 cas bolt.

Its a std bolt, i know this...

Either im definitely a martian or i dont know how to measure a bolt thread but my frost set of dies, specifically m6x1 does not fit the cas bolt thread...

Someone please tell what im doing wrong??

[Ben C34]

IT IS DEFINITELY A M6x1

Maybe your cas thread hole is stripped. you have a bolt to measure, why dont you meaasure it? Regardless its a m6x1. stop asking what it is!!!

also, in relation to your photo you are holding the bolt on an angle, so it wont line up.

Other ideas:

Try a 6x1 tap in the hole.

Take the bolt to a fastener shop and get them to put a gauge on it.

[75coupe]

ill keep asking as long as the tap thread and the bolt thread dont match, thats why its on an angle cock, cause it dont match... Pretty simple, no it aint threaded

There is

ok measured all case bolts turns out the one I was measuring has been stretched at some point in its life.... that explains it
