The BMW 5 Series lug bolts are high-strength, threaded steel fasteners. They are threaded into hubs, securely holding the wheels and tires to the axle hub. As long as you torque correctly, high-quality lug bolts can maintain high clamping force even under extreme operating conditions. The REFERENCE torque spec for BMW 5 Series lug bolts is 140 NM / 103 ft-lbs (always inquire with a tire expert before operating). Without properly working wheel bolts, it would be impossible for a wheel to stay on a car.

Genuine BMW 5 Series wheel 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. Another advantage of steel wheel bolts is the price. If you get steel BMW 5 Series wheel bolts installed, the cost will be inexpensive compared to Titanium replacement. For those looking for cheaper but more durable options, steel BMW wheel bolts are the way to go.
