The basic function of Mercedes-Benz E-Class wheel bolts is to secure the wheels. When upgrading to aftermarket wheels, you may need to replace the stock wheel bolts. Due to the element reaction, the old E-Class lug bolts may corrode or rust and become dirty. Even if one wheel bolt corrodes, your wheels can’t stay properly on a car. Then, it is necessary to replace the rusty wheel bolts with a high-quality set. The thread size of Mercedes-Benz E-Class wheel bolts is M14x1.5mm, and the seat type is a ball seat. Knowing these two factors helps choose the best wheel bolts.
After installing wheel spacers, a set of new Mercedes-Benz E-Class extended wheel bolts is necessary hardware. It is easy to figure out the proper length (stock bolt length + spacer thickness = extended bolt length). For instance, if the OE wheel bolt length is 27mm and you get a 5mm wheel spacer installed, it’s probably best to order 32mm bolts right away. Since aftermarket extended wheel bolts come in various seat types, it is critical that the wheel bolts seat and the wheel lug seat match.
What Mercedes-Benz E-Class Wheel Bolts Do I Need?
At BONOSS, we have lined up proper Mercedes-Benz E-Class wheel bolts from 27mm to 75mm. They are made of high-strength SCM440 alloy steel. After a super one-time forging process, the performance meets the ISO Grade 12.9 standards (tensile strength ≥1,282 MPa, limited life range test ≥2,000,000 stress cycles without damage, ultimate tensile load ≥152,000N, hardness (HV) ≥395). It makes sense that the higher the tensile strength of the bolt, the more force it can withstand more force before breaking.
Besides, these extended wheel bolts are designed with floating seats. The floating seats are replaceable which allows for a perfect fit on any wheel. They are mainly available in two options depending on lug bolt size: conical seat and ball seat. Besides, the separate design eliminates the bolts loosening and the abnormal sound caused by the PCD hole coaxially deviation between the vehicle hub and wheels while driving. With a high-quality user experience as well as a friendly price, such BONOSS forged ISO grade 12.9 wheel bolts for Mercedes-Benz E-Class won’t disappoint you.
