Is it OK to use an oversized torque wrench to break loose small tight bolts?
Never ok
. This torque wrench may be preset to a torque value for small repetitive work, such as receptacle or switch terminations.
What happens if you dont use a torque wrench?
Too tight and something will break
, it may be the thread on the bolt, or much worse the thread on in the hole. Bolts will also break, sometimes leaving a very hard to remove bit in your frame. Not tightenough and it will work loose, and then you know to do it a bit tighter next time.
What happens if you over torque a torque wrench?
Over-tightening
can cause damage to the fastener
, and under-tightening can result in making the item you are attaching or assembling structurally weak and potentially unsafe for use.
What is the lowest setting on a torque wrench?
For big wrenches (measuring in ft-lbs increments) the lowest setting is usually
20 ft-lbs
. If, for some reason, you have a click-type torque wrench that goes all the way down to zero, leave the wrench set to 10 or 20 pounds.
Is it okay to use a torque wrench to loosen bolts?
A torque wrench is a tightening tool.
It is a very sensitive and precise tightening tool, and
should never been used to loosen bolts
.
Is it better to over torque or under torque?
The Importance of Proper Torque
Typically, an
under torqued bolt will
deform and be unable to provide as much clamping force as needed. An over torqued bolt will break.
How should a torque wrench be left after use?
Storage: All torque instruments
should be stored in their original case
. Avoid any torque wrench storage locations that are subject to high or low temperatures and high humidity. “Clicker” style torque wrenches should always be turned down and stored at the torque wrenches lowest possible setting.
Do I really need a torque wrench?
If you plan to do any major work on your engine or on some major powertrain components,
you absolutely need a torque wrench
. Overtightening cylinder-head bolts, for instance, can easily cause expensive damage and catastrophic coolant loss. Too-tight exhaust manifold bolts can cause the manifold to crack.
Can you torque without a torque wrench?
RE: How to measure bolt torque without a torque wrench
The turn-of-the-nut method is generally recognized as a better method of preload control then torque. So,
no need to involve torque in the process at all
.
Are digital torque wrenches more accurate?
Another great benefit of owning a digital torque wrench is that it is precalibrated. When you do have to calibrate a digital wrench, it's easier to do so than it is with a regular torque wrench because
the digital display provides a more accurate measurement
.
Who needs a torque wrench?
Torque wrenches are important to ensure
a balanced rotation of a component in relation to its axis
. For example, fly wheels, wheels, drive shaft. Torque wrenches ensure rotating components with a center-locking nut, such as pulleys, wheel bearing, and fans, are not overtightened.
Does it matter where you hold a torque wrench?
It means that the
actual torque applied to the fastener varies if the hand position
on the wrench is varied (even if the wrench is preset). … Therefore if an operator is holding a “length dependent” torque wrench at the end of the handle, the torque output might be 25 foot-pounds applied for the fastening application.
Can I use a foot pound torque wrench for inch pounds?
Likewise, if you want to convert foot-lbs to inch-lbs, you
simply take the foot-lb number and multiply it by 12
.
Why is my torque wrench not clicking?
Try this …
completely loosen the bolt you are trying to tighten
. Use only the torque wrench to tighten it (never use a torque wench to loosen a fastener). … If it still doesn't click, you'll need a new torque wrench.

Too much force can
cause a technician to strip threaded fasteners or stretch bolts beyond their limits
, which can result in loose nuts or cause the bolt to crack and break.
What happens if you over torque a lug nut?
Excessively tightened lug nuts
can strip the threads, distort brake rotors, damage the wheel, and possibly shear off the lug stud
. Insufficiently tightened lug nuts can come loose, with catastrophic consequences.
