In the automotive world, wheel bolts are small but critical components that keep the wheels attached to the vehicle. With trends as of late, people upgrade wheel bolts purely for aesthetics, but there is more to them than just the looks. When replacing wheels, wheel bolts need to be taken into consideration. Aftermarket wheel bolts come in all shapes and sizes. If you are in process of installing new rims, there is a high chance you need a set of aftermarket wheel bolts with the correct seat types.

If you are looking to run wheel spacers smoothly, the only thing you worry about is the length of the bolts. Many times, in racing, thicker aftermarket wheels and spacers require longer wheel bolts. The general rule of thumb is that you need enough thread length as the diameter of the wheel bolt shows. For instance, an M14x1.25 wheel bolt would need 14mm threads to ensure a safe engagement.

What Does Grade 12.9 Mean on Wheel Bolts?

If you’ve ever spent any time looking at the heads of the wheel bolts, you’ve probably noticed that there are markings that are stamped onto the head. The markings can be numbers, letters, slashes, dots, or an assortment of other marks. If you’ve ever wondered what the markings mean, or if there is some over-arching logic to them, then you are in the right place.

A grade 12.9 marking means the tensile strength of this wheel bolt has reached metric grade 12.9 standards. The metric grades are set according to rules set by the ISO (International Standards Organization). There are four common metric grades: 5.8, 8.8, 10.9, and 12.9. Each grade has a specific bolt strength. The higher number means the higher the tensile strength of the bolt. Grade 12.9 wheel bolts have a minimum tensile strength of 1220 MPa. These tire bolts are very high strength. In fact, they are the strongest wheel bolts that we have covered in the automotive world.
