Genuine BMW lug bolts are made of a wide range of materials from common steel to titanium, and other exotic materials. High-quality steel wheel bolts are significantly stronger and more durable. It is nearly impossible to crack a well-produced steel bolt and bending a steel bolt would require tremendous force. Another advantage of steel BMW lug bolts is the price. If you get steel BMW lug bolts installed, the cost will be inexpensive compared to Titanium replacement. For those looking for cheaper but more durable options, steel BMW lug bolts are the way to go.
But it is worth noting that Titanium BMW lug bolts are much lighter than steel bolts. A set of Titanium wheel bolts can reduce the unsprung weight effectively. Lighter is better. As most people know, reducing unsprung weight makes your car faster. Lighten the vehicle weight decreases fuel consumption and improves engine efficiency, to some extent. Besides, Titanium BMW lug bolts have the benefits of low density, as well as high-temperature resistance. This type of wheel bolt also has an extraordinary resistance to corrosion.
Can You Trust Aftermarket BMW Lug Bolts?
High-quality BMW lug bolts provide a better installation experience as well as good safety. Besides, if you would like to improve the performance, you can replace the OEM BMW lug bolts with ones made of higher-strength materials. If you’ve ever spent any time looking at the heads of the BMW lug bolts, you’ve probably noticed that there are markings that are stamped onto the head. 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.
BONOSS forged BMW lug bolts are made of high-strength SCM440 alloy steel. They are all ISO grade 12.9 certified. A grade 12.9 marking means the tensile strength of this wheel bolt has reached metric grade 12.9 standards. BONOSS ISO Grade 12.9 BMW lug bolts are surely strong enough to handle forces: tensile strength ≥ 1220 MPa, limited life range test ≥ 2,000,000 stress cycles without damage, ultimate tensile load ≥ 152,000N, hardness (HV) ≥ 395. These BONOSS wheel bolts are very high strength. In fact, they are the strongest BMW lug bolts that we have covered in the automotive world.
Are Titanium BMW Lug Bolts Worth It?
Titanium BMW lug bolts are considered to be one of the easiest and quickest items that bring your car to higher performance. Many racing vehicles will use Titanium wheel bolts for strength and lightweight. A thin oxide (TiO2, titania) layer spontaneously forms cover on the surface to protect them against rust or corrosion. If you would like to spend a small fortune getting forged performance wheels to save a few pounds of unsprung weight, why not go the rest of the distance to minimize the extra weight in the BMW lug bolts?
BONOSS Titanium BMW lug bolts apply forged Ti-6Al-4V material. They have been fully TÜV ISO standard certificated: tensile strength ≥ 1,100MPa, ultimate tensile load ≥ 138,800N, proof load ≥ 104,000N, and hardness (Vickers) ≥ 347. Each BONOSS BMW Titanium wheel bolt’s net weight is about 62g, and a set of BONOSS Titanium BMW lug bolts’ weight is about 1240g. Compared with most OEM steel bolts, in the same length, thread, and seat type, the stock bolts’ weight is over 1840g. A set of BONOSS Titanium BMW lug bolts can reduce the unsprung weight by about 600g.
