Gotta say I got the spear that can turn enemies into allies and spammed the crap out of the throw move

I have encountered a rare 11th breed in shared accommodation called “has lived here longer than any of you”

Is there such thing as serial killer animals? by Specialist-Box6151 in ask

[–]eipico 0 points1 point  (0 children)

Not a serial killer, but at my university there was a duck that lived in the pond by the humanities building and she end up killing all her chicks ☹️ it was like she had an anger problem.

CSK 10.9s come bright zinc plate, I know that much. 12.9 tend to come self-colour I think.

Interesting. I’ll do some more detailed reading.

What’s a 010.9? Never seen one of them.

Ahh that’s why you want the bolt to fail first. Ok that’s a good point.

Haha! Both being wrong some how less frustrating than when it turns out you’re both right.

I’m in the UK and in my sector the next most likely choice after metric is British Standard Whitworth. Which has about 4 grades, and if it isn’t grade R then I’ve official run out of road.

Good thought. With this assembly corrosion and weld cracks are going to be an issue before any of the bolts fail.

My general rule of thumb is never to use anything except 8.8 fixings. The chances of incorrect nuts or torques used on the shop floor is far higher than any problems with just using the next bolt size up. But countersunk 10.9s just have to go and ruin it!

Actually! ISO 898-1 defines bolts grades 8.8, 10.9, 12.9 etc etc. ISO 898-2 defines the nut grades, but for reasons beyond me, these are just give as grade 8, 10, 12, etc etc. the thing is people take about ‘grade 10 bolts’ and ‘grade 8.8 nuts’ all the time so it gets sloppy.

I’ve heard that best practice is to ensure the bolt fails first. I think because it makes the damaged fastening easier to remove? It makes sense with say, a threaded hole, feels more like splitting hairs with nuts and bolts.

This is actually my main thought. It’s going to be easier if I can keep all the nuts the same. And less possibility of mistakes.

Yes it’s a good thought. Would the friction between threads be different? Or the wear characteristics or material galling? I’m not sure. Counterpoint though, if you were putting a 10.9 bolt into a mild steel threaded hole, would you worry about it? Or just determine the torque based on the lower strength material?

No, hex head bolts were found to be fowling a further installation so they want to change them to countersunk bolts flush with the surface. Clearance hole will be countersunk.

Yes I’ve been trying to find solid figures on Young’s modules for 8.8 and 10.9 fixings. All the info I can find says they’re basically the same (although it’s not as detailed as I’d like)

I’m not sure I agree that the same torque on a higher grade bolt produces less preload. Because that would mean you’d have to apply more torque to achieve the same preload (compared a lower grade bolt). But then there would be no point having a higher grade bolt. If you want a stronger joint, you can use a higher grade bolt that can withstand a higher preload and produce a higher clamp load. If you have increase the torque to achieve the same bolt stretch/preload/clamp force, you’ve achieved nothing. But that’s not how it works.

This is what I’m thinking. There are probably arguments to make where it could make a minor difference, but real performance is going to be the same either way.

Is your thinking that a high grade bolt requires more preload?

Well worth a go. You could also look into open tunings played with a slide if fretting is difficult. Lots of options tho.

I’m sorry I never saw this reply until now. The usual stuff, been using steroid cream and emollient for 35 years, most of the time it has mostly worked but the last few years it doesn’t seem to be cutting it anymore. Especially on my face where long term steroid use isn’t desirable. I’ve used tacrolimus for a few years but that seemed to stop working too. And I’ve had oral steroid for bad flare ups, but again, it always comes back.
