Wheel stud conversion is often used on European models for the purpose of converting the wheel mounting. Most of the European (Mercedes-Benz G-class) models have hub assembly fixed by wheel bolts, the installation process requires the assistance of a wheel hanger, after tightening the rest of the wheel bolts, the final tightening of the wheel bolts of the wheel hanger, without the help of auxiliary tools, you may need to lift wheels to find a suitable installation position. Most American and Japanese cars are fixed by stud and lug nuts, the stud as a fixed hub assembly structure can provide support during wheel installation, only need to tighten the lug nuts, and the installation process is simple and fast. This way is feasible for European models.
Are Wheel Stud Conversion Safe?
The safety of the wheel stud conversion is mainly related to the installation process and the materials used, the construction of the wheel stud conversion is double-threaded, and the thread on one end fits the wheel holes of the hub assembly (M12x1.5, M14x1.25, M14x1.5) and the thread on the wheel side end provides the mainstream thread data (M12x1.5 and M14x1.5). The car side thread data is more relevant to the vehicle, and the thread data determines the number of turns required for safe installation of the wheel stud conversion, e.g. M12x1.5, which requires approximately 6.5 turns.
How to Install Wheel Stud Conversion Safely?
Standard installation is the basis of driving safety. The minimum number of turns and the locking torque are important parameters for wheel stud conversion installation. Since the BONOSS lug nut has the same grade or performance as the original nut, the BONOSS lug nut can withstand greater tightening torque. However, considering different wheel hubs and original thread, we recommend using the minimum number of turns and torque recommended by the original car for locking. Generally, the minimum number of turns and the locking torque for different threads are as follows:
(Minimum number of turns for wheel bolts / nuts):
M12 x 1.25 = 8.0 turns = approx. 10 mm of load bearing shaft length
M12 x 1.50 = 6.5 turns = approx. 10 mm of load bearing shaft length
M12 x 1.75 = 6.5 turns = approx. 12 mm of load bearing shaft length
M14 x 1.25 = 9.0 turns = approx. 12mm of load bearing shaft length
M14 x 1.50 = 7.5 turns = approx. 12 mm of load bearing shaft length
1/2″ UNF = 8.0 turns = approx. 11 mm of load bearing shaft length
Noted: Forged aluminum alloy lug nuts (Titanium wheel stud conversion) are recommended more tightening the number of turns to ensure load safety.
On the other hand, the safety of wheel stud conversion is related to the material properties. It is well known that due to the superior mechanical properties of the material, titanium alloy is widely used in crucial components, such as rocket engines or aerospace vehicles. BONOSS Forged Titanium Exposed Wheel Stud Conversion applies forged Titanium alloy material. The Titanium alloys are light in weight (each Titanium stud only weighs 62g) as well as very strong.
Wheel stud conversion features great fatigue strength and tensile strength, hard and high-temperature resistance. Even at extreme temperatures up to 400 to 500°C, they maintain great performance. BONOSS Titanium wheel stud conversion is fully TÜV ISO standard test reports certificated, and truly guarantee safety: Tensile Strength≥1,080Mpa, Ultimate Tensile Load≥138,800N, Proof Load≥104,000N, Hardness(Vickers)≥347. A thin oxide (TiO2, titania) layer spontaneously forms cover on the surface, which gives them extraordinary corrosion resistance ability. Each stud conversion is processed Hard-Anodized/Polished surface treatment, smooth 100%. Meanwhile, wheel stud conversion retains the shiny primary color of titanium alloy, shining in the sun which makes your vehicle more outstanding and attractive.
