Always used a torque wrench, what is a Torque Angle Meter?

 

it looks like a short extension with a gauge on it that goes from 0-360*

so if a bolt calls for 55 ft. lbs. + 60* you can get an accurate reading of 60 degrees instead of guessing

 

Where does the 60 deg come in? Is that like 60 deg more tight then the required 55ft on the torque?

 

right, for example, when you torque head bolt it says to tighten them to 22ft lbs, then Use the Torque Angle Meter in order to tighten the cylinder head bolts on the second pass. ^ Tighten the short bolts (3, 4, 7, 8, 11, 12, 15, 16) 67 degrees. ^ Tighten the medium bolts (14, 17) 80 degrees. ^ Tighten the long bolts (1, 2, 5, 6, 9, 10, 13) 80 degrees.

so torque them to 22 ft lbs with a torque wrench. then put the angle meter on, secure it so the meter itself will not spin. turn it until it reads 0,t hen put a wrench on it and turn it until the pointer is at the number of degrees you need.

 

Most bolts will call for a low torque reading (ex. rod bolts @ 20 lb. ft.) to take out the slack. Then you put your meter on and turn the additional specified amount (ex. rod bolts an additional 55°).

most people think that this method indicated torque to yeild bolts (bolts that can only be used once) but thats not true. just becuse they are torqued like this does not automatically make then TTY

go to sears, you can get one for $7.19, its OTC so its a decent brand. Sears item #00971020000

 

I see, but why dont they just add a couple of ft/lbs to the torque setting instead of adding degrees? Is this because you cant get say 35.5 foot pounds? So instead you go 180 degrees?

ENRKyle20, I got this question from that same torque sequence on that other thread you posted in. Kinda ironic lol...

 

The T/A method is used because it provides more accurate means of applying clamping force than torque alone. Friction can throw off a plain torque reading. The higher the torque value is, the more friction there is to throw it off.

 

lol, that is ironic. but yea, shoebox is rights, 90 degrees is 90 degrees on everything, does not mater if that bolt is soaked in oil or dry, its going to get the same ammout of clamping force.

 

I was also thinking that if you have extensions or universal sockets that that too would throw off a true torque setting.

 

Its does.....but depending on the brand etc. Its not a big deal in most cases.
