what is the proper torque for a 9/16" course nut

by Norberto Luettgen Published 2 years ago Updated 1 year ago 5 min read

The standard torque on a Redline Trailer Wheel Lug Nut - 9/16 inch, part # 6-53, is 135 to 145 ft lbs. This is the torque range that is normally used. If the instructions for the wheel are saying 110 ft lbs there might be a reason, like the wheel material, why they are recommending a lower torque.

US Recommended Bolt Torque

Size	Recommended Torque
Size	Grade 2	18-8 S/S
1/2"	37	45
9/16"	53	63
5/8"	73	104

How do you calculate nut torque?

DETERMINING TORQUE

The general equation for bolt load based on applied torque is T = KF_iD_b where K = torque coefficient. K is a function of the coefficients of friction and collar friction in the joint, and these are based on variables such as surface finish, coatings, and so on.Jul 9, 1998

What are the torque specs for lug nuts?

Under- or over-tightening wheel-attaching hardware can be damaging and dangerous.

Hardware Bolt or Stud Size	Typical Torque Range in Ft/Lbs	Minimum Number of Turns of Hardware Engagement
14 x 1.5 mm	85 - 90	7.5
14 x 1.25 mm	85 - 90	9
7/16 in.	70 - 80	9
1/2 in.	75 - 85	8

How do you calculate torque needed to tighten a bolt?

The basic formula T = K x D x P stated earlier takes these factors into account and provides users with a starting point for establishing an initial target tightening torque.

How do you tighten specified torque?

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.

Does thread pitch affect torque?

Thread pitch tends to be more independent of nominal diameter than the other variables. Increasing just thread pitch by 40% cuts tension 5% for a given torque.Aug 18, 2009

What is the torque for a 13/16 lug nut?

Jeremy airjer W. just about any steel wheel lug nut is a minimum of 85 lb. -ft. This includes a good majority of Lighter utility/cargo/boat trailers as well as alot of vehicles and light trucks.

Do you need a torque wrench for lug nuts?

That's why most owner's manuals have a torque specification for lug nuts. 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.Apr 2, 2019

What does NM mean in torque?

newton-meters

The units for torque are newton-meters (Nm) or pound-feet (lb-ft). Newton (or pound) stands for the force that is acting, while meters (or feet) stand for the length of the lever arm. Another name for torque that perhaps gives a clearer indication of its meaning is rotational force.Apr 13, 2021

Does length of bolt affect torque?

Tightening torque is not influenced by the bolt length so easy to standardize. The Bolt efficiency will be low due to wide tolerance of the tension.

Should bolts be lubricated before torquing?

So, torque isn't the true measure of bolt tightness—it's tension. But lubrication on the bolt threads—and a whole host of other factors—can cause fluctuation in torque readings. So once you add a lubricant of any kind to the threads, all bets are off as to whether the same torque setting will truly secure the bolt.

What happens if you torque lug nuts?

Improperly torqued lug nuts or bolts can also result in: 1 Warped brake rotors — brakes grabbing, pulsating or overheated. 2 Damage to the lug nut seating surface of alloy wheels. 3 Wheel hub damage — threaded wholes stripped out.

Does torque stretch a bolt?

Stretch? You might ask – Yes . Proper torque, which stretches the bolt, causes the threads of the stud/bolt to tightly mate and secure to the matching nut or threaded hole (within the axle or wheel hub) without working themselves loose.

What is wheel lug torque?

Wheel lug torque specifications are for clean threads that are free of dirt, grit, etc. If applying an anti-seize lubricant, it is important to note it can be applied only on the threads of nuts or bolts. The lubricant must not be used on either seat of the hardware of the wheel.

What happens if you over torque a bolt?

A bolt that has been over-torqued will be prone to cracking, shearing, loosening, or breaking off which can result in damage to the wheel and other related components. Improperly torqued lug nuts or bolts can also result in: Warped brake rotors — brakes grabbing, pulsating or overheated.

What is thread chaser?

A thread chaser or tap should be used to remove any burrs or obstructions of the threads allowing the lug hardware to be turned by hand until it meets the wheel’s lug seat. Once lugs are snugged down, finish tightening them with an accurate torque wrench.

Why is torque important for wheel assembly?

Using the manufacturer recommended torque also helps guarantee that there isn’t either too much or too little pressure on any of the assemblies to which the wheel attaches. Before you install your wheels, check your vehicle’s recommended torque.

Why use torque on wheels?

Using the proper torque helps ensure that the wheel assembly is securely installed. Using the manufacturer recommended torque also helps guarantee that there isn’t either too much or too little pressure on any of the assemblies to which the wheel attaches. Before you install your wheels, check your vehicle’s recommended torque. Acura.

In Brief: Metric Bolt Torque Chart – Class 8.8, Class 10.9, Class 12.9

These metric bolt torque charts show the ideal tightening torque for class 8.8, 10.9, and 12.9 bolts for both wet and dry tightening. The bolt’s class indicates its material strength, with higher numbers meaning higher tensile and yield strength. The classes are set by the International Standards Organisation or ISO.

Metric Class 12.9 Bolt Torque Chart

Metric class 12.9 bolts are made from quenched and tempered alloy steel and see the most use in heavy-duty applications.

Summary

We hope these metric bolt torque charts have helped you discover the correct tightening torque for the bolts you use.
