The 2023 BMW 7 Series extended wheel bolts are necessary for the slip-on wheel spacers. The extra threads will go through the wheel spacers and wheel to ensure sufficient clamping force to hold all parts in place. We will share with you how to choose the right extended wheel bolts for your wheel spacers and what to look for when installing extended wheel bolts.
How Long of 2023 BMW 7 Series Extended Wheel Bolts?
If you are looking for 2023 BMW 7 Series extended wheel bolts to fit wheel spacers, you need to measure the thickness of the wheel spacers and the length of the stock wheel bolts. If you choose to install 12mm wheel spacers, you will need 27+12=39mm extended wheel bolts. Ensure that the wheel bolts you purchase are the necessary length, as too short may not lock the wheels, and too long wheel bolts cause the wheels to shake.
What Are the Specs of 2023 BMW 7 Series Extended Wheel Bolts?
The specs for 2023 BMW 7 Series Extended wheel bolts refer to the thread, seat type, and thread length. The thread specification is directly related to the torque, and BONOSS recommends installing wheel bolts with a specific thread for the exact torque. BMW 7 Series wheel bolts have M14x1.25 thread, so you should buy the same thread when looking for aftermarket wheel bolts. The torque of M14x1.25 should be 140N.m(103.5Ft-TB).
The 2023 BMW 7 Series extended wheel bolts have the same base as the stock wheel bolts, as they both contact the wheel seat. Stock wheel bolts have a conical seat type, and you can find conical seat products in aftermarket wheel bolts, as most manufacturers make wheel bolts with a conical seat to fit most aftermarket wheels. If replacing aftermarket wheels with ball seats, you will need to look for 2023 BMW 7 Series extended wheel bolts with the same ball seat.
Can BONOSS Provide Wheel Spacers with 2023 BMW 7 Series Extended Wheel Bolts?
On the purchase page of wheel spacers, BONOSS has set up the option to match the 2023 BMW 7 Series extended wheel bolts. The system will automatically match you with BONOSS 12.9-grade wheel bolts, which have higher performance than the stock 10.9-grade wheel bolts. The wheel spacers increase the wheel clearance, and the vehicle drive will produce a large shear force on the wheel bolts, so the wheel bolts’ ultimate tensile strength and proof load will become especially important.
BONOSS offers 2023 BMW 7 Series extended wheel bolts made of SCM440 steel alloy. Their performance is enhanced after forging. BONOSS sent 12.9 wheel bolts to SGS, TUV, and other authoritative third-party institutions for testing in the harsh, destructive test 12.9 grade wheel bolts reached an ultimate tensile strength of 1282 MPa, proof load reached 121,000 N. The outstanding performance allows its large diameter bolts to withstand large shear forces and perfectly transmit the vehicle’s power to the wheel rotation.
