McGard Cone Seat Wheel Lock Bolt Set — M14x1.25 Black (4-Lock Kit)

The 60-degree cone seat geometry makes this set the right call for aftermarket tuner wheels, which typically feature tighter, smaller lug holes than OEM rims. That precision fit matters — a mismatched seat style can damage your wheel or work loose over time, so McGard builds every dimension to exacting tolerances. The bolt stem also carries a dacromet coating on the shank, meeting the same corrosion standards BMW applies to its own fasteners from the factory.

Security is where these bolts genuinely separate themselves from the competition. Each set ships with a computer-generated key pattern that is statistically unique — no two McGard sets share the same profile, and the extra-narrow groove geometry is specifically designed to defeat standard socket extraction tools. The included key features a steel alignment collar that self-centers into the lock face, making installation and removal smooth and controlled whether you're at a track day or changing a flat in the rain.

Before ordering, confirm that your current lug bolts use a cone seat (not radius or flat), and verify your thread pitch and shank length match M14x1.25 at 51.7mm overall length. These locks are rated for aluminum wheels only and will not seat correctly on steel wheels. With McGard supplying wheel locks as original equipment to over 30 global car lines, this is one of the rare aftermarket security upgrades where the quality claim is backed by hard numbers.
