Huge selection of wheel bolts available for all makes and models of vehicles, whether fitted with original or aftermarket alloy wheels.
We offer a huge selection of wheel bolts at WheelPartsDirect.com for all makes and models of vehicles fitted with either original or aftermarket alloy wheels.
It is crucial that your vehicle is fitted with the correct bolts, otherwise your vehicle could be unsafe.
Whether you are changing your current wheel bolts due to changing alloy wheels, damage, corrosion, or because you are wanting to use spacers, our un-paralleled industry knowledge and expertise can ensure that you get the right wheel bolts for your vehicle and wheel combination.
Some vehicles wheel nuts where others use wheel bolts. So what’s the difference?
Wheel bolts have an external male thread which screw into threaded holes on the vehicles hub whereas wheel nuts have a threaded hole which screws onto a external stud on the vehicles hub.
Whether a vehicle uses wheel nuts or wheel bolts tends to follow the pattern of the vehicle manufacturer. For example most Audi and BMW vehicles use wheel bolts, but it’s not always the case, so it’s always best to check your specific vehicle model to be sure.
There are a few factors that make up the fitment of a wheel bolt which are explained below:
Shaft DiameterThe wheel bolt shaft diameter is the thickness of the bolt shaft itself, under the seating of the bolt. This is usually 12, 14 or 16mm.
ThreadThe wheel bolt thread is measurement between each thread. This is usually 1.25, 1.5 or 1.75mm.
SeatingThe wheel bolt seating is where the bolt ‘seats’ in the wheel. It is the shape under the head of the bolt, before the shaft. The shape of the seating can vary. The seating is usually tapered, flat or radius. The most common tapered angle is 60 degree. The most common radius shapes are R12, R13 or R14.
Thread LengthDepending on the thickness of the mounting face on the alloy wheel or if you are using wheel spacers, you can need different length bolts. The thread length is the length of threaded part of the external shaft.
Shaft LengthThis is the total length of the shaft, from the bottom of the seating to the end of the bolt. It is normally the same measurement as the thread length, however there are some bolts that have an area of blank shaft before the thread starts, this is where the thread and shaft length measurements would differ.
Hex SizeThe size across the flats on the head of the bolt. It would also be the size socket or wheel brace you would use. The hex size is usually 17, 19, 21 or 22mm. On commercial vehicles and 4x4s this can sometimes be 24mm or 27mm.
These are also sometimes called slimline or small diameter bolts. They tend to be used on aftermarket alloy wheels where the bolt holes are too narrow for a conventional thickness of bolt. They tend to use an internal drive key which goes into the bolt head and then you use your socket or brace on the key head.
Sometimes known as ‘wobbly bolts’ these bolts allow you to fit a wheel with a slightly different PCD onto your vehicle. The difference can only be up to 2mm, the most common use of variation bolts is fitting 100mm PCD wheels onto 98mm PCD hubs. You can also get variation bolts in the tuner style.
