How do you measure torque on a bolt?

After fastening the bolt, make use of a torque measuring tool to mark off the tightened bolt and the product/workpiece. Apply additional force in the tightening direction until movement is noticed. Recording the reading will indicate the residual torque originally applied to the joint.

Do tire shops use torque wrenches?

Too much, and they can damage the hub, warp, deform, or shear. Too little, and they can rattle loose. So, for every tire job, you must deliver a discrete, specific amount of torque to each nut—which means torque wrenches are indispensable equipment for every tire shop.

What can you use in place of a wrench?

Why should you not overtighten screws?

Everyone who has ever worked with fasteners has accidentally messed one up at some point. One of the most damaging ways to do that is by over-tightening, or over torquing the fastener. This can result in stripping screws, snapping screw heads and damaging pre-tapped threading.

What happens when you reuse head bolts?

A head bolt should not be reused if the threads are galled or badly damaged. Chasing damaged head bolt threads with a die will clean up the threads but also remove material (metal) and undermine the head bolt’s ability to torque down and hold to specs.

Can I change my tires without a torque wrench?

The short answer is no, they’re not absolutely necessary. The longer answer is that if you can, you should. Which is why I recommended above that if you change a tire without one, it will get you on your way again, but it’s still a good idea to have the nuts checked and properly retightened.

It is pretty safe to say ARP Ultra-Torque Fastener assembly lubricant is good to use on all head bolts that are not manufactured by ARP and, of course, on ARP head bolts. ARP says, “We recommend using ARP Ultra-Torque lube to ensure an even, accurate clamp load and to prevent thread galling.

Do head bolts need washers?

Yes, you need washers under the heads of the head bolts. Without the washers, the bolt’s head will cut into the aluminum causing uneven loading of the bolt torque.

How tight should a car wheel nut be?

The optimum torque value for your car or mounted rims can be found in the vehicle manual. It depends on the car model, rim size, design (aluminium or steel rims) and number of bolts. It is normally between 110 N⋅m and 120 N⋅m.

Is it OK to hand tighten lug nuts?

Can your tires be on too tight?

After a tire rotation or bolting on winter tires, experts recommend a follow-up visit to have lug nuts tightened because of “settling” that occurs in the first 100 km after the new wheels are put on. If lug nuts are too tight, they can damage the brake rotors. If they’re not tight enough, they can work loose.
