Bolt length is measured from under the flange (or taper seat) to the tip of the threads. For most BMW X Series models, the OEM shank length is typically 28mm–40mm (≈1.1"–1.6"). If you're running aftermarket wheels with a thicker hub face, you may need a longer bolt — generally add the extra wheel thickness to your OEM length. When in doubt, check your wheel's seat depth or contact us to confirm.

Grade 5 titanium (6AL-4V) has a tensile strength of approximately 130,000 psi (≈895 MPa), which is generally comparable to or exceeds many OEM steel lug bolts. It also offers a significantly better strength-to-weight ratio, making it a popular choice for performance and track applications.

Yes. Grade 5 titanium (6AL-4V) forms a natural oxide layer that provides excellent corrosion resistance in most environments, including road salt, rain, and humidity. It is generally more corrosion-resistant than standard steel hardware, making it well-suited for year-round driving in coastal or northern climates.

These bolts feature M14 x 1.5 thread pitch, which is the standard fitment for BMW X Series vehicles. The seat type is a ball seat (radius seat) to match BMW OEM wheel specifications. Please verify your wheel's seat type before ordering — using the wrong seat type can cause improper seating and unsafe conditions.

M14 x 1.5 is the standard thread pitch for most BMW X Series models, including the X1, X2, X3, X4, X5, X6, and X7 across multiple generations. However, compatibility can vary by model year and trim. We recommend confirming your vehicle's OEM bolt spec before purchasing.

For most BMW X Series applications, the recommended torque is typically 100–120 Nm (74–89 ft-lb), but always refer to your vehicle's service manual for the exact specification. Titanium fasteners generally do not require anti-seize compound, but a light application is sometimes used — consult your installer if unsure.

In most cases, no special tools are required beyond a standard torque wrench and the correct socket size for your BMW's lug bolts (typically 17mm hex). A calibrated torque wrench is strongly recommended to avoid over-torquing, which can damage titanium threads. Do not use an impact gun without a torque stick.
