I never fully trust the snap type torque wrenches & would put more

uncalibrated?). Unless the snap type is calibrated before use, there
could be quite a bit of error in it. The beam type only has to return
to zero after each use.

Anyone else have similar or different thoughts on this? The world
seems to have gone to snap types.

I've got a guaranteed 4% accurate $napOn clicker that comes through
cal within the 4%, but needs tweaked about every other year.

Don't do much of it anymore, but have got a Mac Tool$ bender ($10 at a
garage sale) that gets cal'ed every year (heh) that gets used for
cylinder bases & other mission critical stuff.

Like you said, if a bender reads O, it's extremely likely to be OK.
Cheap clickers tend to crunch instead of click, but have one in the
shop that gets sent every 12 months and gets tweaked about every three
years (that would be LESS often than my $napOn)

Toughest thing to do with a properly cal'ed clicker is not pull it
through the click & over-torque a little.

Another thing that is a MUST with the clicker torque tools is to unload
them after each use. Do not leave them set to a torque.
