Thank you my friend. I can tell you that every fastener on a vehicle has a rundown strategy that is electric. There is not a single impact wrench in any plant that will be used in assembly that runs forward. The are used for teardown only. Every fastener is installed with a computer controlled torque gun that has complex programs that monitor torque and angle data, and they are extremely accurate.

I agree and you are correct. However, the main purpose of this video was to emphasize the difference between torque and angle. Some people make the mistake of adding a few more pounds of torque to makeup the angle. This can be catastophic. I just want to make sure nobody gets hurt from an improperly tightened fastener.

My Karma is strong because I really want to teach and help people. The example you gave is one I hear often, which is why I made this video. A lesson to anyone who reads this, NEVER re-use a fastener that is torque to yield. Using that method stretches the fastener and puts it close to failure, Using it again is a guranteed failure. Thank you for sharing your experience Leigha...you Karma will help others.

You don't sound like a noob....you can't know everything...Lord knows I don't. You are 100% correct. As long as you do not exceed the maximum torque for the fastener you will not enter the yield phase. As long as you know the fastener material, grade, and size you can look it up. Any fastener that has angle applied to it has gone past "A" and has started to yield and must be tossed out when removed. Great question!

@jetforceracing2151

Thank you for taking the time to execute this simplified explanation. My takeaway is that, in layman's terms: 1) You torque a bolt to a specific predetermined value and stop then, 2) You turn, torque or tighten the same bolt a little or a lot more using another tool called an angle gauge and stop. Questions: A- Should one presume that the torque value is necessarily set at the maximum torque point for a given fastener? and therefore the degrees values = the point at which the bolt begins to stretch? I am torqueing an aluminum cylinder head to an aluminum block. The bolt specs are: Cylinder Screw M11, Service Limit: 148.5 mm (5.846 in.). This is what the shop manual instructs: "First torque to 40 N*m (30 lbf*in). Then tighten screws turning an additional 120 degrees rotation with a torque angle gauge and finish tightening with a 90 degree rotation. Torque screws to 10 N*m (89lbf*in)." My understanding is: Step1: Torque to 40 N*M, then Step 2: Rotate 120 degrees, then Step 3: Rotate another 90 degrees, then Step 4: Torque again (another) 10 N*M Am I understanding this correct?

Hello. Very Complex video, great job :) I work as an engineer, daily calculate bolt connections for large industrial gearboxes acc to VDI 2230 german standard. There it is different: We never calculate bolts up to yield point, because due to yield you can loose pretension force in the bolt. Normally, we calculate 90% bolt utilization, that means 90% of yield stress. this is partially because there are many factors which are uncertain during calculation (torque wrench measure tolerance, friction coeficients between mating surfaces...) and because of that it is hard to determine exact final stress in the bolt, so there is an margin to avoid yield point.
@PetesGarage
@PetesGarage 3 года назад
That makes sense. I would not want a large industrial bolt to be tightened to yield. Thank you for sharing that.
@PetesGarage
@PetesGarage 11 лет назад
Yes. What you are doing is called "conditioning" the fastener. When you do this you must use new bolts. The purpose of this step is to get all of the threads on the bolt and in the hole "lined up" so to speak so the torque and angle step is secure. Go to 22 and then back off a couple turns. Then torque all to 14 in the specified order. The add the angle in the same order. If you don't have an angle gage turn the wrench from 12 to about 5 o'clock in one continuous motion. Nothing is dumb.

Amazing video--I agree with Auto Body Everything! I've long known about torque angle specifications and that they are to be used in some applications but never understood why they're different from simple torque wrench settings. Pete's Garage makes this easy enough to grasp without delving into an entire course of study. I'm sure the thumbs down are from those who have nothing better to do than bash others or simply don't understand---which I don't understand but WTH huh? :) Thanks so much Pete's Garage!

Let's discuss. Torque can only be measured if there is an equal and opposite reaction. You are correct. Equilibrium must be achieved only if a force is applied. I think we are close on the definition. I enjoy the discussion. You are very astute.

That is correct. The reason I made this video is because many people say " just add a little more torque to do the angle," but that is so wrong. As you are learning about the eloasticity modulus watch how the curves change with different materials. 20 degrees of angle on a 1020 steel bolt has a different curve than 316 stainless.

Yooooooooo!! thanks a lot for all this info, I was really really confuse with all this angle/torque situation many manuals say, I was wondering if it has to be with plastic and elastic deformation but I never knew about this graphic you explained, really helpful info and I'll make sure to measure those nuts every time I have to open a engine for first time and shows signs of being poorly assembled. I'll be explaining this info to more people and try to avoid this overtight situation, it's sooooooo common here in Latinamerica, I saw people assembling engines without a torque wrench or proper tools, them end up lasting a few thousand miles...

That is the most common question. It is tough to wrap your head around the fact that angle has no relation to torque. Angle is a different calculation for every fastener material / base material combination. Toque is a resistance to rotation, angle is a clamping force, two totally different things.

The videos I make are driven by phone calls I receive. When I made the 3.4 head gasket video I had hundreds of calls & had to explain angle and torque-to-yield fasteners to most everyone. I analyze torque and angle data every day in an engine plant and it is immensely important to understand what it means. The data can tell me if there is a cross-threaded fastener, chips in a hole, or a bad part. It is an intricate science, I'm not an expert, but I tried to make it easy to understand. Thanks!

Well explained and much to think about . If your torque wrench is calibrated or if you use the degree tool and follow the chart on torque & stretch specifications you have other factors to consider . The quality of the threads on either the nut , bolt or machined part . We are left with trust of a manufacturer to produce a quality part . The metal , threads and heat treating process have to be consistently the same . This to give repeatable and consistent torque & stretch applied to each nut & bolt . If you are blue printing an engine that will be pushed to its limits , these are some of the many important things to consider .

56 Nm is not too high for a 10mm bolt, however, anything, especially grease, will shift the torque curve later in the tirghtening sequence and definitely cause a thread to strip. A fastener must be dry unless the manufacturer specifies a lubricant and different torque settings. Unless you have a unique deflecting beam torque wrench, you will not hear a click. You have to watch the needle and stop when it gets to the right torque. Clean threads and have faith in the wrench.

Torque to yield fastener specifications most common call for a torque and angle. Like 110 ft lbs with 95 degrees of angle. You can torque in sequence in stages, but the angle must be applied in one, continuous motion. I have never seen a 35°+5° spec, but I would do the 35° in sequence on all bolt and add the 5° as a second step.Thanks for watching!

There is a LOT more to it than torque and stretch bolts as aluminium castings are usually porous. To get around this problem, castings that are subjected to pressure are Vacuum Varnish Impregnated. If the cylinder head is skimmed this VVI layer will be lost although there is a company in the Manchester area that will re-impregnate castings. Empirical results with the Peugeot 106 diesels indicate that the original head gasket will last for about 50,000 miles but replacement gaskets will only last about 30,000 miles. Of course the alloy in an old engine will be impregnated with oil. The small car to have in the Peugeot range was the now classic 205 with the iron engine as that was a horse of a different colour! 250,000 miles was quite possible and the extra weight on the driving wheels could be very useful!

Anti-seize compounds contain nickel to reduce galvanic corrosion. It will act as a lubricant as any other material would. There is no rule of thumb. Every fastener is different. The presence of anything acting as a lubricant causes the resultant torque to be lower. The threshold torque starts later so the angle can go past yield. I think you'd be safe with a 10% drop. Torque/angle applies maximum clamp load so loc tite is useless. Nothing should be applied unless the manufacturer recommends it.

I just had my first experience with Torque-to-yield bolts. ( Stretch bolts ) I figured out real quick, they are single-use. You never re-use them. I suppose you could if you could tell where it was starting to stretch and stopped right there... but I can't. I just dropped my 1/2" torque wrench at Alaska Matrology and Calibration Services where they do a lot of them for the Oil-patch on the North Slope. I drug them through the mud on this, and they said my Torque Wrench had to hold within 4% of it's setting, throughout it's range. That was important for me to know. So. 4% of 10 foot pounds, or 120 inch pounds... I thought the same as you said, but in the real world... Doesn't matter. Thanks! Mark

Thanks for your reply Pete,my wrenches are an aussie make ,i dont know if you know them , Warren and Brown, it has a beam which deflects on to as set value and clicks out a spring loaded pin which "clicks' and the pin never popped. I think ill have to experiment on some test fasteners to get a feel for it, but it sure shakes your confidence ,this was a pretty simple job and i stuffed it.Keep up the good work.

Thanks a lot, I knew the operation but had no idea what was the purpose to add angle after torque tightening.
