A torque specification chart explains the correct torque for a variety of nut and bolt types. The charts tell mechanics, builders and assembly workers how to tighten each nut and bolt for maximum efficacy. Most charts identify bolts or nuts by size and the number of threads per inch. Depending on th
Auto mechanics use torque specification charts to ensure that fasteners of all types, especially bolts and screws, are neither too tight or too loose. Proper tightening is critical for wheels, as well as engine and transmission parts that rely on a gasket to contain a fluid.
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.
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
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.
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.
Use a tire torque chart by finding the make, model and year of your vehicle on the chart and reading the appropriate torque measurement. The torque measurement is the amount of torque required by each of the wheel's lug nuts. Too much torque over-tightens the lug nut, potentially stripping the threa
The website Tork Spec allows users to access torque specifications for a variety of cars sold in the United States. It has a broad collection of torque specifications, including both engine torque specifications and model torque specifications.
