torque wrenchs

[midniteblues]

Somewhere some how I aquired a 1/2" drive hf torque wrench.
So I decided too test it.
Now I'm no dept. Of measures and scales here so a simple performance test was done just too check it.

I also used my 3/8"drive snap on and a 1/2" drive craftsman torque wrenchs too compare it too.

All are click types, no beam wrenches.

What I found was the craftsman and snap on stayed within 2-4#''s of each other all the way up too 100#'s (this is the max for the 3/8" snap on).

The hf stayed within 5#''s of the other 2 up too about 50#'s.
After that it started to fall way behind.
With the other 2 At 60#''s the hf needed to be set at 80#''s too match 60.
And it just got worse from there.

With the 2 at 100#''s the hf was maxed out at 140#''s too match them.

Now since Idk where the hf came from (kid didn't know either) I'm not sure if it was treated properly or not but figured it would be nice too know if it worked correctly or not
I figured this would be the one I would lend out if someone asked.

Just thought I would put this out there just in case somebody has some critical torquing too do with a hf wrench you better check it too be sure it works right.
I wouldn't even use it for lug nuts.
