The Home Depot, Amazon.com and Craftsman sell torque wrenches. Craftsman only sells its own brand, with wrenches ranging in diameter sizes from 3/8 inch to 1/2 inch.
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 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
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.
Torque in cars is a measure of how much turning force the engine can provide, which indicates how fast the car can accelerate. Cars with more torque have an easier time reaching higher speeds, towing heavier loads, moving from stand-still and climbing hills.
Check for the appropriate amount of torque and turn the torque wrench in a clockwise motion against the bolt until the indicator or the gauge shows the desired ft-lbs. When tightening bolts on a car wheel, the recommended amount of torque is usually listed in the car owner's manual.
Basic torque conversion charts are available from The Tool Hut and Proto Industrial. These charts convert value from pounds per foot to Newtons per meter. Tool manufacturer websites may be a better choice for consumers looking for torque conversion information for a specific tool.
