Stretching / Torquing a bolt

[NitroDann]

I dont know why this is an argument?

Ive just never heard heard anyone say it like that.

That is all.

Mod, to clean the thread please?

Since ARP have been mentioned:

Fastener installation Overview
The importance of tightening fasteners to their required preload cannot be emphasized enough. If a fastener is not tightened properly, the fastener will not apply the required preload on the application it is being used for and may become susceptible to failure. Conversely, if a fastener is overtightened and stretched too much, it becomes susceptible to failure by exceeding it's maximum yield point.
There are three generally accepted methods employed to determine how much tension is exerted on a fastener:

1.Using a torque wrench
2.Measuring the amount of stretch
3.Torque angle (rotating the fastener a predetermined amount)
Of these methods, measuring the amount of stretch of a fastener has been proven to be the most accurate. However, since stretch can only be measured with the use of specialty type gauges or expensive ultra sonic measuring equipment, it is only practical for measuring the stretch on connecting rod bolts and other fasteners, where it is possible to monitor the overall length of a fastener, as it is being tightened. Since most fasteners are installed blind and can't be accessed from both ends to monitor stretch, one will most likely use a torque wrench or other torque angle monitoring device for the majority of assembly work.

Rest of the article http://www.arp-bolts.com/pages/technical_installation.shtml

At my work (construction) we mainly use torque angle and squirter washers.

Man, I love forums.

Even when people agree with something, there's always an argument to be had!






Seriously, how did an abnormal use of a term become something to argue about?


If I post that "electrically incandescent filament devices for light provision are used in cars" and somebody says "I agree, but usually people just say light bulb" I wouldn't suddenly leap at them.

I would coz. the first is pure wankerism, like saying I hang with engine builders (sirry Dann, bit lame) or I have a smarty pants contract law tutor.

Seeing as someone has moved this into its own realm, let's see if we can get to 10 pages before someone locks the thread

Don't underestimate the power of stupid in large groups.

I am more interested in little decks contractual law abilities!

He can have my job then

That ARP link is awesome!

I hadn't heard of it referred to as stretching either - must just be a Newcastle thing Dann

I am always super careful with my torque wrench to stop it from going out of calibration - never realised they can go out even without rough treatment!

I'd clean the thread, but I'm not a mod in this part...

To be honest guys this is what I was annoyed about.

Dude...!

what.?

You can say all you like about the miscommunication of text, but if you read it the way its punctuated (pauses, exclamations and all) it's just condescending and addressing me like I was posting crap and had no idea what I was talking about.... his post did not say anything about it being called something else or anything, and when someone else pointed it out he back pedalled to some dumb thing about my implying the bolt is stretched prior to assembly (struggling to see how you would get there). Then when that was also pointed out to be plausible in some applications Dann then back pedalled some more...

Don't get me wrong, I've met Dann and he is a pleasant guy to speak to & I think some of the fab work he does is nice particularly considering what he has at his disposal... however he is a young guy like me and does not know all there is to know, I by no means believe that I know everything either, I would say I know less than Dann, being that I study law and only tinker with cars when Dad really needs a hand or at the race track.

However, I am young (22) and probably a little too proud so when I think someone is trying to make me look like a fool more often than not I will react with vigour (I'm hoping my adversarial nature will lead me to a lucrative career at the bar).

I apologise if that was not the intent but from the context and tone of the posts I don't really see it any other way.

In our assembly shop we must check our torque wrenches against a standard and document for QA purposes several times a day.
the standard gets checked and recertified several times a year.

You posted a single sentence outside of a conversation and with no context.

If you walked into a crowded room and suddenly exclaimed "dogs are only as vicious as their training makes them" what response do you expect? everybody to agree, or people to say "what!?" because out of nowhere a random comment has been made.


I really can't see why somebody would be offended by that, if Dann wrote "what was that you farking moron?" then maybe, but instead it was one word.

In my opinion you can't take forums too seriously, they will always attract trolls and the socially abrasive. Hopefully the decent and reasonable folk outnumber these types.

The remainder of the conversation remains in the thread... and the conversation was to do with the quality of conrods and then rod bolts which my comment was in relation to.... I was sure that most people would be well enough versed in the ways of the world wide web that they could go and read the rest for themselves and make their own inferences... if they actually care that is... the example you give about dog shows is just ridiculous and in no way correlates.

Which thread?

Post #1 of this thread was:

Even the best quality rod bolt is worthless unless its stretched properly

Where was the conversation? it's post #1, there is no prior conversation.



The dog comment relates to how when there was no conversation about dogs a person comes in an makes a statement (much like you did at the start of this thread) that in the main context seems completely random (because there was no prompt for it, nor any conversation happening about it)

If you posted that statement as a response to an engine building thread it probably wouldn't have had the same response, because there's a context for it (being conversations about engine parts)

This thread was pulled out of Lokiel's garage thread given little decks response to NitroDann.

Can't we just keep it to the topic?

little decks - you've explained your position, there really isn't any need to digress from this thread and bury the intended information.
