McGard Wheel Lock Nut Set - 5pk. (Cone Seat) M12X1.5 / 3/4 Hex / 1.46in. Length - Black

Five-Pack Wheel Security Built to Outlast Every Theft Attempt

The McGard 24526 Wheel Lock Nut Set delivers military-grade wheel security in a plug-and-play package engineered to fit the M12 x 1.5 thread pattern common across Ford Bronco, Chevrolet Blazer, GMC Jimmy, and a wide range of sport utility vehicles. Each lock is fully machined from restricted-chemistry, through-hardened steel and finished with multiple layers of nickel plating topped by a black PVD microporous chrome coat that resists rust and corrosion far longer than standard chrome finishes. The 24526 replaces one lug nut per wheel with a computer-generated unique key pattern that defeats every standard socket and bolt extractor on the market today. McGard has supplied wheel locks as original equipment to major automakers worldwide since 1964 and manufactures the 24526 in the USA to meet or exceed OEM torque and safety specifications.

About McGard

McGard has been manufacturing wheel security products in Orchard Park, New York since 1964. As an original equipment supplier to most major automakers worldwide, McGard holds the standard for wheel lock design, producing every lock from proprietary restricted-chemistry steel heat-treated and precision-machined in-house. Their computer-generated key patterns ensure that no two McGard wheel lock sets share an identical code, and their plating process meets or exceeds the corrosion-resistance requirements of the OEM brands they supply. The 24526 reflects that same quality standard in a direct-to-consumer package.

Frequently Asked Questions

The McGard 24526 is a 5-piece black wheel lock nut set with an M12 x 1.5 thread, 60-degree cone seat, and 3/4-inch hex. It includes four locks for road wheels, one lock for OEM rear-mount spare tire carriers, and one uniquely keyed socket for installation and removal.

The 24526 is designed for vehicles using M12 x 1.5 lug nuts with a 60-degree cone seat. Confirmed fitment includes 2021-2024 Ford Bronco (excluding Raptor), 1991-2002 Chevrolet Blazer and S10 Blazer, and 1991-2001 GMC Jimmy and S15 Jimmy. Always verify your vehicle's thread pitch and seat style before ordering.

No. The Bronco Raptor uses a different lug nut specification. The 24526 is not listed as a compatible fitment for the Raptor. McGard offers separate wheel lock sets for Raptor applications.

The 24526 uses a 3/4-inch (19 mm) hex key size. The included keyed socket uses a steel collar to guide precise engagement and prevent the tool from slipping off the lock face during installation or removal.

No. McGard specifically instructs against using an impact wrench. Over-torquing can damage the lock pattern, distort brake rotors, or create uneven clamping force. Always use a torque wrench and tighten to the specification found in your vehicle owner's manual.

Each 24526 set carries a computer-generated key pattern that is statistically unique. The extra-narrow groove in the lock face is engineered to block the intrusion of standard bolt extractor sockets and reverse-thread removal tools. The through-hardened steel resists cutting and drilling attempts that would compromise conventional lug nuts.

The thread pitch is M12 x 1.5, matching the OEM lug nut specification on a wide range of domestic and import SUVs and trucks. If your vehicle uses M12 x 1.25 or a different thread, the 24526 will not fit. Verify your vehicle's lug nut specification before purchasing.

Yes. This product is sold with a California Prop 65 warning for cancer and reproductive harm. Wash hands after handling. For more information, visit www.P65Warnings.ca.gov.

McGard includes a personal code card in every 24526 package. This code allows you to order a replacement key directly through McGard's customer service at mcgard.com. Keep the code card in a secure location separate from the vehicle.

Installation Instructions

1. Confirm your vehicle uses M12 x 1.5 lug nuts with a 60-degree cone seat before starting.
2. Remove one OEM lug nut from each wheel and from the spare tire carrier mount.
3. Thread one McGard 24526 lock nut onto each wheel stud by hand. Do not cross-thread.
4. Engage the keyed socket with the steel collar seated fully against the lock face.
5. Using a torque wrench (not an impact wrench), tighten each lock to the torque specified in your vehicle owner's manual.
6. Install remaining standard lug nuts and torque in the manufacturer-specified crisscross pattern.
7. Remove the key socket and store it and the code card in a secure, off-vehicle location.
8. After the first 25 miles of driving, retorque all wheel locks and lug nuts to spec.
