McGard Tuner-Style Cone Seat Wheel Locks M12 x 1.5 — Black, Set of 4 + 1 Key, Hardened Steel

McGard 25357 tuner-style cone seat wheel locks are a one-piece black security set (4 locks + 1 unique key) engineered to protect alloy tuner wheels with M12 x 1.5 threads.

Engineered and manufactured in the USA, these McGard wheel locks combine hardened steel construction with a multi-layer nickel and microporous black chrome finish to resist corrosion while matching the tight lug-hole tolerances of tuner-style alloy wheels. The one-piece design installs and removes like a standard lug nut but requires a unique key, and a steel collar on the key keeps the key aligned for quick, reliable use. These locks are intended specifically for alloy tuner wheels with cone seating and small lug-hole recesses.

How do these locks fit tuner-style alloy wheels?

These locks are shaped and sized to fit into close-tolerance lug-hole recesses typical of tuner wheels. They use a cone seat profile and a shorter overall length to sit flush without interfering with the wheel’s design. Confirm thread pitch and shank length before ordering.

• Thread size: M12 x 1.5
• Seat style: cone seat (for tuner wheels)
• Overall length: 1.24 inches — made for limited recess depth
• Hex size: 13/16 for standard wrench compatibility

What security features prevent theft and tampering?

McGard locks use through-hardened, restricted-chemistry steel and computer-generated, unique key patterns to resist cutting and common removal tools. The extra-narrow pattern groove reduces the risk of tool intrusion, and the steel collar on the key keeps alignment for consistent engagement during installation and removal.

• Fully machined from through-hardened steel for strength
• Computer-generated unique key patterns — low risk of duplication
• Extra-narrow pattern groove resists tool access
• Steel collar on key guides and stabilizes during use

How durable is the finish and construction for road use?

McGard applies multiple nickel layers plus a microporous black chrome layer for superior corrosion resistance and a tuned aesthetic for black tuner wheels. The plating process and tempered steel construction are designed to withstand road salts, moisture, and normal wear without flaking or rusting quickly.

• Three nickel layers plus microporous black chrome topcoat
• Plating intended to protect against rust and environmental wear
• Through-hardened and tempered steel core for long-term durability
• Manufactured in the USA to OEM-quality standards

Who is this for: These McGard 25357 locks are for owners of tuner-style alloy wheels who need a compact, high-security locking solution that fits tight lug-hole recesses. They suit drivers who want a black finish to match tuner aesthetics and require OEM-level durability. Do not use on steel wheels or wheels requiring a seating type other than cone; always verify thread pitch, seat style, and shank length before purchase. Note that keys are unique per set and will not match factory or other aftermarket lock sets.
