I have this torque wrench that reads in foot pound/newton meters and you twist the handle upward to increase force. My question is the foot-pounds starts at 25ftlb but the 25 mark has a line below it and on it _/- kinda like that. anyone have a torque wrench like this, how do you know its on 24?i'm confused
 
That would lead me to believe that it only goes as low as 25ft# Setting the torque wrench below that could (will) damage it. The manufacturers make them that way because it is very difficult to make a torque wrench that torques high to be able to be calibrated low. The lower the torque wrench goes the harder to calibrate it.
 
Hi man!
It`s kind of hard to explain this with text, I also had trouble understanding how to adjust the toeque wrench, but I just studied it for a while and then it all came clear to me.

The scale that is on the handle that you turn around, has a number of lines, if you set the handle so that it`s flush with one of the lines on the wrench itself, then rotate then handle while you count how many lines that pass the scale on the wrench, until you reach the next horizontal line one the wrench itself, then you will know how many steps there are between each number on the wrench.
Like I said it`s kind of hard to explain.. .

However if the lowest number on your wrench is 25 then it ain`t suppost to handle torques below 25. But I`m not sure.. .

Read the manual :) (if you have it).

:)
 
the torque wrench numbers start at 25 and increases numbers by 15. The 25 has a line below it going to 15 but no number and thats where it all starts...so i'm going to zero it on 15 and count 9 on the twist handle and that should be 24...right?
 
you will need a torque wrench in inch pound if u wanna go lower then 25 foot pounds ..or buy another that go below 25 ... if its start at 25 its the the lower the guage can go...
 
I WOULD NOT USE THAT TORQUE WRENCH it will not be accurate!
lots of people use beam torque wrenches for under 25# and clicker for over 50#
IMO
 
......

Its my torque wrench and its a weird set up, it is acc. and it does read 1 ft/lb to 175 or somthing like that, i jsut didnt have the time to show eric how to use it, i thought that he saw me use it on my SXR....Im not cheap when it comes to my tools, 6 grand into tools just for school, ($300 for that torque wrench)
 
I dont think anyone is saying someone is cheap, justgoin off what we read

If you have to torque something to 24 lbs and the wrench only goes down to 25 lbs, just torque it to 25. Most torque wrenches are out 1 or 2 lbs anyway. If you apsolutely must have it at 24 for piece of mind, use another wrench.
 
I used the torque wrench and it felt like it was doing the job correctly, the line actually starts at 15 but there is no number..the numbers increase by 15..such as 25,40,55 etc..so i set it on 15 and turned the handle up 9 clicks to reach 24..
 
yup as others said i have an inch pound wrench for the smaller stuff and a big mofo for the bigger stuff. Mine goes down to 25 ft-lbf as well, so below that i just use the in-lbf wrench. If i didnt have the smaller one i would just go to 25 on a 24 ft-lbf rated bolt though.
 
Eric.... I have what may be the same toque wrench.... the line look similiar to _/- twist the handle so it reaches the bottom line... then if you follow the slanted line and it should be pointing to the desired torque setting
 
They only did this so that they could stamp all the number on the handle and have the still be readable instead of clumped together
 
I wouldnt use that torque wrench. Try to find one that has a scale closer to what you need. A torque wrench is most accurate in the middle of its range.
You dont need to spend a lot of money either. A click type torque wrench (no matter what brand) is not usually as accurate as a beam type torque wrench. The reason click types are better is they are more convienient( you dont have to look at it. I use torque wrenches daily in my profession and quite often people think they are doing well by using a torque wrench, when they really arent using it properly.
When you are torqueing a bolt make sure the bolt is turning when the wrench clicks or the beam reaches the scale, because the force required to break free the stationary bolt may be more than the actual torque of the bolt. In which case the wrench would click but the bolt could back out. This can cause errors as much as '20lbs. They other thing people commonly do is continue to tighten after the wrenck clicks.

you dont need an inch pound wrench that is too small a scale instead you need one with a 5 to 75 scale

also you dont want to loosen it past the minumim setting or else it will loose its calibration, and after use store at lowset setting.

I would just torque them at 25 to be safe IMO.
