Bolt areas (Tensile stress area, Minor diameter area, Shank area) 4

[mte12]

It's difficult to find a table that includes all the bolt areas mentioned in title, for all bolt sizes.

The closest I found was this web page:

Standard Metric Bolt Shank Dimensions

Bolt sizes, diameters, tensile stress area, thread shear area, and fastener stress analysis data for designers and engineers.

raanz.org.nz

Is there a table available that includes bolt sizes for larger bolts, above M36.

In context, bolts used are to Australian Standard, either grade 4.6, grade 8.8 or grade 300 to AS/NZS 3679.1.
I have tried calculating areas from first principles in standards (a while ago), but found a difference with tabulated tensile capacity and shear capacity.
So far the above web page gives expected capacities as tabulated.

Is there a table which extends the data in above web page?

I assume you've typoed 4.8 instead of 8.8?
Also, I've never come across a G300 bolt, that would be reo or steel plate surely?
Honorary mention to Grade 5.8 or 10.9, though they're not often used

AS/NZS 1252.1, AS/NZS 5131, NZS3404 all only cover up to M36, I'm not sure why
Above that you may have to ask manufacturers for specific info

AS1275 goes up to M64 and has formulas for stress area. Why do you need a published table if you have the formulas?

They are tabulated in ASI design capacity tables.

This on line doc has the data although not in one page.

Thanks for responses.

Greenalleycat, yes typo was fixed. I hadn't come across it either until now, a different discussion, but standard AS/NZS 3679.1 does cover rounds in Table 12, then threaded.

Tomfh:
Just revisited AS 1275, that's where I started from memory, it does go up to M64, the Tensile Stress Area for tension is there, but for Minor Diameter Area is what I think I had issues with (for shear).

sdz, thanks for link, but could not see data for bolts larger than M36.

I made a spreadsheet for this because I found the various areas so confusing and hard to calculate

Here are the areas up to M64:

Great, thanks bugbus, this will assist a lot

I'm curious... What are you guys using M64 for!? Tightening one beyond snug would be an interesting process.

And if you are playing in that world I would have thought you'd be all over it!

 

[mte12]

Yes human909 ... if M64 exists, as I've seen many suppliers list it, I'm sure it's used ... anyway it's for a check of M42 and M48 bolts, designed by others ... maybe didn't occur to you that's possible?

 

[human909]

I think you missed the humour and the genuine interest in my post.

 

[bugbus]

The largest I’ve seen was for the baseplate of a cantilever sign gantry over a road I designed, which had M42s in Grade 4.6 from memory.

Wind turbine bolt cages are a beast to behold too:
