McGard’s easy to use, one-piece wheel lock functions like a regular lug nut or bolt, but requires a special key tool for installation and removal. Its design allows for an unlimited number of different computer generated lock and key patterns. This unique wheel lock system is continually being refined and improved upon. McGard Locks are made in the United States to meet or exceed O.E.M. standards for safety and durability. Presently, McGard is an Original Equipment wheel lock supplier to over 30 car lines around the world. Compare our features and you’ll see why McGard is the best wheel & tire protection available.

1. 8 Different Key Hex Sizes

McGard is the only manufacturer to offer 8 different key hex sizes to match the vehicle’s original equipment lug wrench. Your customer will appreciate this important feature when they have to change a flat tire along the roadside.

2. User Friendly Keys

The Wheel Lock's steel collar guides the key into the lock pattern. Simply place the key over the lock and turn until the patterns engage. The collar holds the key in alignment for easy installation and removal.

3. Extra Narrow Groove Patterns

The computer generated key designs allow for an unlimited number of key patterns. The narrow groove resists the intrusion of lock removal tools into the pattern.

4. Triple-Nickel Chrome Plating

The best in the industry. Our process includes three layers of nickel and one layer of microporous chrome. The first layer of nickel is for corrosion resistance; the second layer of nickel is for luster and the third nickel layer interacts with the microporous chrome layer to disperse nature’s corrosive action (rust).

5. Through-Hardened Steel

McGard uses only restricted chemistry steel, made in the United States, specifically for McGard. These special standards insure the structural integrity of each and every fully machined McGard wheel lock. Every lock is through-hardened and tempered, reaching the depth of hardness needed for its unsurpassed level of security (unlike case hardening which is only a surface treatment).

6. Precision Threads

Core integrity and precision machining provide the highest strength in the industry. All McGard locks and lug nuts meet or exceed the highest OEM proof load standards, 135,000 to 160,000 PSI.

7. Precise Bearing Surface

McGard’s standard for concentricity of the bearing surface to the pitch diameter is 30% more precise than OEM standards. This insures even distribution of the clamp load and uniform seating of the lock to the wheel.
