Hummer H2 Wheel Lug Nuts & Bolts

A wheel lug nut or wheel nut is a fastener used to secure a wheel on a vehicle. Lug nuts and bolts are found on every vehicle and help secure the wheel to the wheel hub. They are made of steel and most and have a rounded or conical (tapered) end. Typically, a set of lug nuts are used to secure a wheel via the wheel studs to the hub which attached the wheel to the drive axle. There are many types of lug nut but the most common ones are Conical tapered, ball radius, and flat seat. Most aftermarket wheels require the use of different lugs to match the new wheel's seat. Some designs use lug bolts or wheel bolts rather than nuts, which screw into a tapped (threaded) hole in the hub, brake disc or brake drum of the wheel. On many cars, wheel bolts are standard and use a threaded stem that is attached to a tapered head and matches the wheel insert. The bolt goes straight into the hub, and locks it in place with the axle and passes through the brake disc or drum. Wheel studs and lug nuts are different in that the lug nuts screw onto studs that run from the hub through the brake disc or rotor to the wheel whereas the studs are mounted directly to threaded hub ends The advantage of wheel nuts over wheel studs is greater as they allow ease of wheel change by holding the wheel as you thread the lug nut on instead of trying to hold up the tire while lining up the holes to insert a bolt. Failure to use the correct lugs or wheel bolts may cause the vehicle to vibrate and damage the wheel and axle over time. Many large vehicles are equipped with loose wheel nut indicators to permit early detection of loose lug nuts. The sensor spins with the nut, so a visual inspection is enough to detect it.

Usually, a set of lug nuts is used to secure a wheel to threaded wheel studs, and thus to the axles of a vehicle. Some designs use lug bolts or wheel bolts rather than nuts, which screw into a tapped (threaded) hole in the hub or brake drum or brake disc of the wheel.

Wheel studs are the threaded fasteners which hold many automobiles on wheels. They are placed semi-permanently directly at the centre of the engine, normally via the brake drum or brake disc. Wheel bolts use a threaded stem attached to the tapered head which matches the insert of the wheel. The bolt goes straight into the hub, locking it in place from the axle, through the brake rotor.
