Why do European cars use wheel bolts?

What is the reason behind European cars using bolts? It makes putting the wheel on harder, and if the bolt is seized, or breaks, you now have to back it out, and possibly retap the hub or replace it. On a lug/stud car, you can crack the nut, then just hammer out the stud and replace it if it is stuck.

Why do some manufacturers use lug bolts instead of mounted wheels on studs with nuts?

Nuts on studs leave the studs prone to getting knocked and damaged when the wheel is off, or being removed/replaced. Using a bolt means that the vulnerable part of the thread (the bit most likely to be hit) is on the bolt, which is easier and cheaper to replace than a stud.

What is the purpose of lug bolts?

Wheel Lug Nuts are a tapered nut used to fasten the wheel to the threaded wheel studs connected to your car’s axle. Wheel Lug Bolts fasten the wheel of your car to wheel’s hub or brake drum.

Why are there different lug patterns?

The arrangement of how they are spaced around that hub is called the wheel’s bolt pattern. The vehicle’s bolt pattern will determine which wheels of a given diameter and width will fit and which won’t. It’s also common for different manufacturers to use different bolt patterns than other manufacturers.

What cars use wheel bolts?

A set of lug nuts is typically used to secure a wheel to threaded wheel studs and thereby to a vehicle’s axles. Some designs (Audi, BMW, Mercedes-Benz, Saab, Volkswagen) use lug bolts or wheel bolts instead of nuts, which screw into a tapped (threaded) hole in the wheel’s hub or brake drum or brake disc.

Why are wheel bolts not studs?

Studs protruding from the hub offer an easy way to align the wheel when mounting. This allows consistent torque values for all studs. Contrastly, when bolts are installed into the wheel hub, more torque is needed to overcome the friction between the bolt and the hub.

Why do some vehicles have more lug nuts?

Lug nuts are designed to hold a certain amount of pressure, which is why larger vehicles have more lug nuts. After you lose one lug nut, that pressure has to be distributed to the other lug nuts. The wheel bearings will have to hold more pressure than the others sides, which can cause them to wear prematurely.

What is a wheel lug stud?

Wheel studs are the threaded fasteners that hold on the wheels of many automobiles. Lug nuts are fastened onto the wheel stud to secure the wheel. When a wheel is removed for tire changes etc., the stud remains in the hub. Many automobiles instead use bolts to do this, where removable bolts screw into the wheel hub.

What does the bolt pattern mean?

Given in a two number system, a bolt pattern, also known as the lug pattern, is the measurement of an imaginary circle formed by the lug holes at the center of your wheel. For example, a wheel with a 5-100mm bolt pattern has 5 lug holes equally spaced around a circle with a 100mm diameter.

What are the different bolt patterns?

Bolt patterns can be 4-, 5-, 6-, or 8-lug holes. A bolt circle of 4×100 would indicate a 4-lug pattern on a circle with a diameter of 100mm. The diagram (upper, left) indicates the proper measuring methods. 6-lug wheels are measured like 4-lug wheels.

Why are lug nuts called lug nuts?

Typically, lug nuts are found on automobiles, trucks (lorries), and other large vehicles using rubber tires. What is the meaning of “lug” here? According to the Etymology Dictionary, “lug” is “a broad-meaning word used of things that move slowly or with difficulty”.

What is a bolt pattern on a wheel?

Key Identifying Wheel Dimensions: Wheel Bolt or Lug Pattern (or bolt circle, lug circle, lug pattern, etc.) is the measured diameter of an imaginary circle formed by the centers of the wheel lugs or bolt holes. Bolt patterns can be 3, 4, 5, 6, 7, 8 or 10 lug holes.

What is the difference between lug nuts and wheel fasteners?

While it’s difficult to break with the use of traditional terms (i.e. “lug nuts”), the term “wheel fasteners” is more appropriate. Remember that not all automotive wheels are secured with studs and nuts. For example, many German vehicles use wheel bolts instead, which engage into threaded holes in the hub face.

What are the different types of wheel nuts?

The “seat” refers to the contact area between the base of the fastener head and the wheel’s fastener pocket. Although variations exist, three basic seat styles are in common use today. These are conical, radius and flat-seat types. Conical wheel nuts (or wheel bolts) feature a straight taper at the seat area.
