Lug Nuts – To Properly Secure Wheels
A wheel nut or a lug nut is a kind of fastener. It is a type of nut which is used for securing the wheels and tires on a vehicle. It is usually found on trucks, lorries, sport utility vehicles and other large cars that have rubber tires. A wheel nut is a nut which has a conical, tapered or rounded end. It is used in most steel and aluminium wheels.
A set of Lug nuts are usually used in cars to secure its wheel to the threaded studs of the wheel, thus connecting it to the axle of the vehicle. However, there are many car manufacturers, who instead of Wheel Lug Nuts, use lug bolts, which is screwed into a threaded (tapped) hole in the wheel’s dick brake, drum brake or hub. This kind of configuration is also known as bolted joint. The wheel nut’s taper is usually sixty degrees. 45-degree taper is ideal for wheels of racing cars. It is designed to secure the wheel tightly on the axel of the car, and to prevent the nut from getting lose. Some cars use a spherical nut rather than a tapered one. Wheel lug nuts come in different shapes and sizes. Forged rims and aftermarket alloy rims often need specific type of lug nuts to match the mounting holes of the wheel. For this reason, a new set of wheel nuts is often needed when the rims need to be changed. There are mainly four kinds of lug nuts. They are spline drive, under hub cap, bulge cone seat and cone seat.
Wheel Lug Nuts – To Prevent Theft of Alloy Wheels
A lug nut can be removed using an impact wrench or a lug socket. For removing the wheel, an automotive jack or a hydraulic jack is used to lift the car first. Wheels that have hub covers or hubcaps must be removed beforehand with the help of a screwdriver, prybar or flatbar. Removing the lug nut is a challenging task since it can get frozen to the stud of the wheel. In those case a breaking bar can be used to loosen the lug nuts. To remove stubborn lug nuts, you can use an impact range to give repeated blows or try alternating between loosening and tightening.
Alternating pattern must be used to install Wheel Lug Nuts. It is also known as star pattern. This technique ensures equal load distribution across the mounting surface if the wheel. When you are installing lug nuts, it is advised that you use a calibrated torque wrench to tighten them up. While an impact wrench, socket or lug can be used to secure the nut, the final tightening should be done using a torque wrench to ensure adequate and accurate load is applied.
