Pontiac Montana Wheel Lug Nuts & Bolts

Used to hold a wheel on a vehicle, a wheel lug nuts and bolts or wheel nut are fasteners, actually a nut or bolt. Lug nuts and bolts are typically found on rubber tires on automobiles , trucks, and other large vehicles. A lug nut is a nut fastener, used on steel and most aluminium wheels, with one rounded or conical (tapered) end. Typically, a set of lug nuts is used to secure a wheel to threaded wheel studs, and thus to the axles of a vehicle. There are four common types of lug nut cone seat, bulge cone seat, under hub cap, and spline drive. Most aftermarket wheels require the use of various lugs to match the new wheel seat. Many designs, instead of nuts, use lug bolts or wheel bolts that fit into a tapped (threaded) hole in the centre of the wheel or brake drum or brake disc. Most of the cars come with either wheel studs or wheel bolts from the factory. In many vehicles, wheel bolts are standard, and use a threaded stem attached to a tapered head that fits the wheel insert. The bolt goes straight into the hub, locking it in place, from the axle, through the brake rotor. Wheel studs and lug nuts are different in that the studs are mounted in the hub, rather than using a single piece that screws into the hub, and stick out beyond the brake rotor hat. The wheels are mounted with lug nuts, screwed onto the stud. The advantage of wheel bolts over wheel bolts is greater ease for tire changes by creating the ability to lift both the wheel and tire onto the bolts creating the ability to hold and locate the assembly during tire changes, rather than trying to hold up the wheel and tire while lining up the holes to insert a bolt. Unless the appropriate lugs or wheel bolts are not used, the vehicle may vibrate and may cause them to loosen over time. Many large vehicles are equipped with loose wheel nut indicators to allow for early detection of loose lug nuts. The sensor spins with the nut, so that visual inspection will detect it.

Wheel studs are the threaded fasteners which keep many cars' wheels on. They are mounted semi-permanently directly to the hub of the vehicle, usually via the brake drum or brake disc. Wheel bolts use a threaded stem attached to a tapered head which fits the insert wheel. The bolt goes straight into the hub, locking it in place, from the axle, through the brake rotor.
