How much torque do you need to tighten something?
When you use your hands to tighten something, you need to know how much torque to apply. The average human hand can apply about 100N of force to a small screw. Torque is measured in Newton-meters (Nm), a unit of force equal to the force times the radius of a circular hole.
How much torque can you apply with your hands?
The average torque a human can apply with his hands is 2ft-lb for a bolt to turn, while females can only manage one-third of this torque for 4 minutes. The magnitude of grasp moments increased with target force.
What is the torque of a hand tool?
A torque of a hand tool is the force applied to a hand by a linear force. Torque is also called the moment of force. This indicates the tendency of a force to turn a body. The term torque dates back to Archimedes who studied levers. The average human hand is capable of applying up to 100Nm of torque.
How much weight can a 1/4 inch drive shaft take?
If you assume a reasonable quality tool steel that can handle 100K psi, a 1/4" drive can take about 30 ft-lb, 3/8" about 100 ft-lbs, 1/2" about 230 ft-lbs, and 3/4" about 800 ft-lbs. Really good steel will bump this up, while special tools like a wobble extension may cut it to half. Show activity on this post.

How much torque can a 3/8 drive handle?
150 ft-lbs will break a 3/8" drive usually and about 300 ft-lbs will break a 1/2" drive. These are on regular breaker bars that are partially hollow and have the little ball in the space of the head to hold the socket. A SOLID 1/2" heat treated impact rated drive anvil will go up to about 1200 ft-lbs.
How much torque can a chrome socket take?
Impact wrenches were designed with higher torque in mind — they bust bolts loose or torque them up in excess of 1000-foot pounds.
How much torque can a breaker bar apply?
Because of their designs and components, breaker bars can bear higher torque levels to remove rusty nuts and bolts. In fact, breaker bars that can handle up to 2,000 pounds of maximum torque are fairly common.
How much can I torque by hand?
The hand tight torque value is the amount of torque required to turn a fastener by hand. This value is typically between 0.03 and 0.05 Nm for most applications.
Can impact sockets handle more torque?
Impact sockets are robust sockets that are designed for impact drivers such as impact wrenches, and industrial torque wrenches that can deliver higher torque than other wrenches.
Why are impact sockets black?
Impact sockets are typically black. This is because the surface is carbonized in order for it to harden. Ensuring that the surface is hard allows the sockets to absorb sudden torque changes i.e. “impact” a lot better.
How much torque can a 3/8 impact socket handle?
90 to 100 ft/lbsIndeed, 3/8-inch impact wrenches generally deliver 90 to 100 ft/lbs of maximum torque, whereas 1/2-inch impact wrenches often offer at least 300 ft/lbs of maximum torque.
Is it bad to use chrome sockets on an impact?
Safety First Chrome-plated sockets should never be used with an impact driver. Regular chrome-plated sockets can crack or shatter and send pieces flying. Use only impact-rated sockets for impact guns, and impact-rated sockets or nut drivers for smaller cordless impact drivers.
How much torque can a 3/8 breaker bar take?
3/8 gives you 20 -100 ft/lb or torque where 1/2 gives you 50-150 ft/lb. If it is more than 100 or less than 3/8 won't work same for 1/2.
How much torque can a 1/2 drive ratchet take?
Super Duty Air Impact Ratchet Wrench (Max. Torque 120 Ft-Lb)
Is it OK to use a torque wrench as a breaker bar?
Never use your torque wrench as a breaker bar—that'll damage the torque mechanism.
How much torque can a normal socket take?
Quarter-inch drive click wrenches can use most standard sockets and can tighten fasteners that need anywhere from 20 to 250 inch-pounds of torque. Inch driver versions can be set from 150-750 foot-pounds for heavy-duty manufacturing.
Can I just use impact sockets for everything?
Impact sockets can be used safely on a hand tool, however you should never use a regular hand tool socket on an impact wrench as this can be extremely dangerous. A regular socket is likely to shatter when used on power tools due to their thinner wall design and the material they're made from.
Can you use deep sockets with a torque wrench?
Short answer : no, you can't apply the force suddenly enough to make the socket flex to make a difference - what can skew the readings or, at least, the torque applied is friction between the nut or bolt head and the surface it is mating to.
Can you use impact sockets with ratchet?
You can absolutely use an impact socket on a hand tool ratchet, a breaker bar or a torque wrench without damaging the tool or placing yourself at risk. New impact sockets are designed with a shoulder that is stepped down to a parallel neck.
How much lbs will break a 3/8 drive?
I tested this out accidentally while doing an axle nut. 150 ft-lbs will break a 3/8" drive usually and about 300 ft-lbs will break a 1/2" drive. These are on regular breaker bars that are partially hollow and have the little ball in the space of the head to hold the socket.
How much weight can a 1/2 drive extension hold?
So I think it would reasonable to say that, even with a tiny factor of safety, a 1/2 drive extension should be able to handle 1000 lb ft
How much weight can you break on a 3/8 breaker bar?
if you have high quality tools it is common to get 200-230 lbs on 3/8 breaker bar but you will most likely be using a cheater pipe to add a foot or two of leverage. If you do the same to a ratchet it will probably break at 200 lbs. assuming the tooth count is high (90- 100).Ratchets with lesser tooth counts are stronger and normally come in 1/2 inch drives. see youtube for demonstrations.
What size drives are needed for a Fed spec?
This spec gives test-torque requirements for 1/4, 3/8, 1/2, 3/4 and 1.0 inch drives for ratchets, universals, hinged breaker bars, extensions, etc.
What is the maximum socket size for 1/2"?
Maximum socket size I can find for 1/2" is 36mm, that translates to an M24 fixing: http://stainlessautomotivefastenings.co.uk/pdfs/HEXAGONHEADIDENTIFIER.pdf
How much torque do I need?
Calculating the torque required for a particular application can be done in a number of ways. If you are driving a pump or similar piece of equipment it may be as simple as contacting the manufacturer or consulting the datasheet to see what they recommend for that particular application.
How fast is 20000/60?
