McGard chrome cone seat wheel lock set 1/2"-20 — 5-piece kit with key, corrosion-resistant finish

McGard has produced premium wheel locks in the USA since 1964, and the 24538 set continues that tradition with heavy-duty materials and a precision key system. This five-piece kit includes four locks for the road wheels and one for a rear-mounted spare carrier, plus a single key designed to align easily and resist tampering. The locks are machined from a restricted-chemistry steel, through-hardened for strength, and finished with multiple plating layers for corrosion resistance and a polished appearance.

How does the McGard 24538 protect my wheels?

These locks act like standard lug nuts but require the supplied McGard key to remove them, creating a physical barrier against casual wheel theft. The lock pattern is computer-generated, making patterns effectively unique across sets.

• One-piece lock design resists standard removal tools.
• Extra-narrow pattern groove reduces insertion by pry tools.
• Through-hardened restricted-chemistry steel for durability under torque.
• Unique, computer-generated key pattern for set differentiation.

Will these locks fit my vehicle and spare carrier?

The 24538 kit uses a 1/2"-20 thread size and cone-seat geometry; it’s intended for many cars, trucks and SUVs that accept this thread and seat type. It also includes a configuration specifically intended for vehicles with an OEM rear-mounted spare tire carrier.

• Thread size: 1/2"-20 — verify your vehicle’s lug thread.
• Cone seat — ensure your wheel’s lug seat matches cone geometry.
• Includes one lock sized for a rear-mounted spare plus four road-wheel locks.
• Compatible with many OEM applications; check fitment before purchase.

How easy is installation and daily use?

Installation mirrors standard lug nut installation and removal, with the supplied key guiding and aligning quickly by hand. The key features a steel collar that centers the key in the lock pattern, making it straightforward to use with a wrench or socket.

• Install and remove like regular lug nuts using the supplied key.
• Key collar keeps alignment for faster, easier operation.
• Works with standard lug wrenches or torque tools once key is engaged.
• One key operates all five locks in the set — store it securely.

What materials and finish protect the locks from weather and wear?

McGard manufactures each lock from a restricted-chemistry steel formulated for high strength and through-hardening for integrity under load. The visible finish is achieved through a multi-layer plating process that improves corrosion resistance while maintaining a bright chrome look.

• Restricted-chemistry steel, fully machined and through-hardened.
• Plating: three nickel layers plus one microporous chrome layer.
• Polished chrome finish for long-term appearance and rust protection.
• Manufactured in the USA with globally sourced components.

Who is this for? The McGard 24538 set is aimed at vehicle owners who want a higher-quality wheel lock built to OEM standards: owners of passenger cars, trucks and SUVs that use 1/2"-20 cone-seat lugs and those who need a secure locking solution for a rear-mounted spare. It’s a good match for drivers who prefer a durable, well-finished locking system that installs and removes like ordinary lug nuts while adding an extra layer of protection. Always confirm thread size and seat type for compatibility before ordering, and store the matching key in a safe place to avoid being locked out of your wheels.
