McGard Wheel Locks M12 x1.5 Cone Seat Set of 5 — Black, One-Piece Security Locks with Key

McGard 24526 cone-seat wheel locks are a five-piece security set (four road wheels + one spare) with a matching unique key, engineered to protect 60° tapered-seat wheels from theft while delivering a durable black finish.

These wheel locks are precision-machined in the USA from specially specified, through-hardened steel and finished with multiple nickel layers plus a microporous black chrome layer for corrosion resistance. Designed as one-piece lug-style locks, they install and remove like standard lug nuts but require the included McGard key tool to operate. The set includes five locks and one key and fits applications using an M12 x 1.5 thread and a cone (60°) seating surface.

How do these wheel locks fit my vehicle?

Fitment depends on three measurable factors: thread pitch, seat style, and shank length. The 24526 set uses M12 x 1.5 threading and a 60° cone seat; it won’t fit wheels that require flat or radius seating or different thread sizes.

• Thread Size: M12 x 1.5
• Seat Style: 60° cone (tapered) seat
• Overall Length: 1.46 inches; dual hex sizes 19mm & 21mm
• Includes five locks plus one unique key tool and ID card

What security features prevent theft and tampering?

McGard wheel locks use computer-generated key patterns with extremely narrow pattern grooves to resist common removal tools. Each lock is through-hardened from restricted-chemistry steel for added toughness, and the one-piece design avoids weak joints that could be exploited.

• Unique key pattern — many combinations, low duplication risk
• Narrow pattern grooves to deter tool intrusion
• Through-hardened alloy steel construction for strength
• One-piece lock design functions like a standard lug nut

How do I install and use the McGard key tool?

The supplied key features a steel collar that guides and aligns the key into the lock’s pattern, making installation and removal straightforward with common wrenches. The collar keeps the key steady so you can apply torque without cross-threading, yet the locks can only be operated with their matching key.

• Insert key into lock, collar centers the key for alignment
• Use a 19mm or 21mm socket on the key outer hex to turn
• Keep key and ID card stored safely; keys are unique per set
• Note: Keys will not match other McGard sets or OEM locks

What finish and durability can I expect from the black locks?

McGard applies multiple nickel layers followed by a microporous black chrome layer to create a cosmetically refined, rust-resistant surface. This plating protocol provides long-lasting appearance and corrosion protection while maintaining the mechanical integrity of the hardened lock body.

• Triple nickel base layers for adhesion and durability
• Microporous black chrome for a dark, protective finish
• Finish resists rust and stands up to road conditions
• Manufactured to meet or exceed many OEM standards

Who is this for? Drivers and fleet managers who need theft-resistant wheel protection for vehicles that use M12 x 1.5 threads and a 60° cone seat will find this McGard 24526 set appropriate. It’s ideal for owners who want a reliable, OEM-quality locking solution made and quality-checked in the USA, and for anyone who wants a matching spare-lock arrangement (four road wheels and one spare). Before purchasing, visually confirm your wheel’s seat type and use the vehicle-specific fitment tools or manufacturer guidance to ensure compatibility.
