Begin with the formula
T = K x U x D x P
, where T is the torque, K is a standard representing 1.33, U is the coefficient of friction, D is the diameter of the fasteners, and P is the necessary preload.
How do you read a bolt torque?
How do you read torque wrench specs?
Look at the meter at the bottom of the torque wrench.
The numbers represent the amount of torque in either foot-pounds (ft. -lbs.) or Newton meters (Nm). Wherever the arrow is pointed designates the amount of torque that you’re applying to a lug or nut. In the stationary position, the wrench should read 0.
How do you use torque specs?
What is the torque for 5/8 Grade 8 bolt?

How do you read foot pounds on a torque wrench?
What does NM mean on torque wrench?
A torque wrench is a precision tool which guarantees reliable and quality tightening. Its use is essential to avoid any deterioration or breakage on the various clamping parts. The tightening torque is expressed in
Newton Meter
(N.M). The N.M represents the moment of a force of 1 newton with a lever arm of 1 meter.
What is torque setting?
What is the torque setting for (the rotating ring with figures)? This setting
lets you control the torque or turning power of the drill driver
. The higher the torque (number on the torque ring), the more ‘power’ the drill driver produces and the deeper the screw can be driven into the workpiece.
Can you over torque with a torque wrench?
So long as users operate with caution and do not exceed the maximum torque
, most torque wrenches can be used for undoing. However, if the bolt will not free within the maximum torque of the wrench, another tool should be used instead.
What is the torque for 1/2 inch bolt?

Can I use a inch-pound torque wrench for foot pounds?
Torque wrench conversion method
If you want to convert inch-lbs to foot-lbs, you take the inch-lb number and divide it by 12
. Likewise, if you want to convert foot-lbs to inch-lbs, you simply take the foot-lb number and multiply it by 12.
How many inch pounds does it take to make a foot-pound?
So just as
12 inches
equal 1 foot, 12 inch-pounds of torque equal 1 foot-pound.
What does 5 nm torque mean?
5nM is
approximately 45 in/lbs (inch pounds) or 3 ft/lb (foot pounds)
. VERY LITTLE TORQUE!
What is 1 Nm of torque?
One newton-metre is
the torque resulting from a force of one newton applied perpendicularly to the end of a moment arm that is one metre long
. The newton-metre (also newton metre or newton meter; symbol N⋅m or N m) is a unit of torque (also called moment) in the SI system.
Is 500 Nm torque good?
It’s worth noting that engines producing much more than 400 Nm (295 lb/ft) of torque, whether petrol or diesel, are usually at their best teamed with an automatic gearbox.
Beyond 500 Nm (369 lb/ft), most engines come with an automatic gearbox anyway since they’re better able to cope with an engine that strong
.
What does NM mean on a drill?
What is torque for power tools? Torque, measured in
Newton Metres
(Nm), is the force that causes an object to rotate and is the best gauge to see how powerful your drill or impact driver is and the higher the number in newton metres the more twisting force it will deliver.
What is the torque for an M10?
