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.
What does 3/8 torque wrench mean?
3/8-inch is the necessary size for engine repairs such as tightening spark plugs. 1/2-inch. As mentioned above, this is the choice if you’re looking for a torque wrench to have on hand for tire changes. 3/4 to 1-inch. This size is fairly specific to larger vehicles such as construction vehicles or semis.

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 NM mean 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.
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.
Whats better 3/8 or 1/2 torque wrench?
The 3/8 drive is perfect for engine work like timing belt assembly, front covers, water pumps, cam covers, oil pans, etc. The 1/2 is ideal for heavier type fasteners like lug nuts, suspension, steering, engine mounts, etc.

What are the 3 types of torque wrenches?
There are four basic types of torque wrenches, each with slightly different operating principles: beam or deflection, dial indicator, clicker, and digital.
How do you calculate foot-pounds of torque?
One pound (force) = 4.448 222 newtons. This gives the conversion factor: One pound-foot = 1.35582 newton metres.Pound-foot (torque) pound-foot Unit system British Gravitational System, English Engineering Units Unit of Torque Symbol lbf⋅ft or lb-ft Conversions.
Can I use a foot-pound torque wrench for inch pounds?
If it is a digital torque wrench you can switch between ft lbs and inch lbs, if it is a mechanical wrench you will need an inch lbs torque wrench specifically. You can multiply ft lbs by 12 to to get inch lbs but most ft lbs wrenches do not adjust low enough for inch lbs work..
Is ft-lb the same as lb-ft?
The short answer is no. They are each separate, distinct units of measure. Work is the measurement of force over a given distance. So one foot-pound-force (ft-lbf or just ft-lb) is the energy required to move a one pound object one foot of linear distance.
What torque is considered hand tight?
RE: Hand Tight Torque Be EXPLICIT about the torque limit: “TIGHTEN to 4 ft-lbs of torque. NEVER USE MORE THAN 5 ft-lbs of torque!” in your instructions.
How many inches is a pound?

How do you calculate torque multiplication?
How to Calculate Gear Ratios and Torque Multiply the force acting on the first gear by the first gear’s radius. Divide the second gear’s radius by the first gear’s. Multiply the gear ratio by the input torque that you calculated in Step 1: 2 x 600 = 1,200 newton-meters.
What do you use a torque multiplier for?
A torque multiplier gives its users a mechanical advantage when loosening and tightening nuts, bolts and other items meant to be motivated through torque. Among its benefits are upgraded safety, greater precision and better efficiency and productivity.
When would you use a torque multiplier?
A torque multiplier is a tool used to provide a mechanical advantage in applying torque to turn bolts, nuts or other items designed to be actuated by application of torque, such as the actuation of valves, particularly where there are relatively high torque requirements.
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 is 30 Nm in foot-pounds?
22.127 ft-lbs Newton-meters Foot-pounds 25 Nm 18.439 ft-lbs 30 Nm 22.127 ft-lbs 35 Nm 25.815 ft-lbs 40 Nm 29.502 ft-lbs.
Should you double click a torque wrench?
Double checking your torque is never a bad thing. By double clicking, you are allowing the fastener to rest for a second, then you are back at it to get the proper amount of torque there.
Can you loosen lug nuts with a torque wrench?
Should you use a torque wrench to remove lug nuts? No you should not. You should not use a torque wrench to loosen anything as a general rule. The manufacturers instruction manual will say whether or not that specific torque wrench is designed for loosening fasteners.
How do you use a torque wrench for beginners?
To use a torque wrench, adjust the handle and set it to a specific level of torque. Use the tightener on the end of the handle to lock it in place. Then, fit it over the socket, nut, or bolt and turn it clockwise to tighten it. When you’re done, turn the settings on the handle back to 0 and store it somewhere safe.
