A lug nut is one of the fasteners that attach a car wheel to its hub. A car wheel has four, five, or six lug nuts depending on its make and model.
The appropriate torque for lug bolts varies depending on the vehicle and can range from 50 foot-pounds to 350 foot-pounds. The correct torque specifications for a vehicle can be found in the owner's manual, at a vehicle's dealership or in a repair manual for that specific model and year.
The effect of the wheel lug torque depends on how much the applied torque deviates from the recommended car torque. While overtightened lug nuts cause vehicle vibration during braking, overstretches and weakens the wheel studs, undertightening causes wheel wobbling and unbalance during driving. Corr
Most frequently, use a lug wrench or tire iron to remove lug nuts. Alternatively, use a spider wrench, which is a cross-shaped tool with varying sized sockets on each tip.
To remove a rounded lug nut, purchase a rounded-lug-nut-removal tool from a local auto repair shop. Many lug-nut-removal tools are sold with a set of socket-type ends in various sizes. To use the lug-nut-removal tool, choose the appropriately sized socket from the set and twist it onto the lug nut.
A wheel lug nut torque chart indicates the proper amount of torque, or twisting force, to apply to the lugs nuts found on vehicle wheels. Mechanics need to apply proper torque when tightening lug nuts to ensure damage does not occur to the wheels.
Removing a damaged wheel nut requires using several different types of techniques that can loosen the nut from the stud. There are also specialty sockets available that have rigid grooves along the inside surface, which secure it onto the damaged lug nut so it can be loosened.
The torque specifications for an axle nut depends on the application of the axle nut and can vary slightly from company to company. The factory manual for the vehicle likely mentions the axle nut specification.
To choose the right lug nut or wheel lock for a car wheel, several dimensions and characteristics on the wheel studs and the lug nut itself must first be determined. These dimensions and characteristics include the thread size and pitch, the seat type of the lug nut and the dimensions of the lug nut
Running torque defines the amount of torque a component needs in order to keep spinning at a constant angular velocity after it starts spinning. Measuring running torque is important for identifying quality issues with an assembly or defective components.
