Select 1980-2025 Vehicles McGard SplineDrive Lug Nut Installation Tool For 1/2-20/M12X1.5 & M12X1.25/13/16in. Hex - Single

If you're running McGard SplineDrive locking lug nuts on your Mustang or F-150, this is the tool that gets them on and off. McGard builds it to match the SplineDrive pattern in 1/2-20, M12x1.25, or M12x1.5 thread, with a 13/16 inch hex end for a breaker bar, ratchet, or impact gun.

Why Upgrade to a Dedicated SplineDrive Key

• Sized specifically for McGard SplineDrive lug nuts in 1/2-20, M12x1.25, or M12x1.5 thread, so it engages the lock pattern it's built for.
• Ends in a 13/16 inch hex, so it drives with a breaker bar, ratchet, or impact gun instead of needing a specialty driver.
• Made for SplineDrive locks only, per McGard, not a multi-pattern or universal key.

Fitment Notes

This tool isn't matched to a Mustang or F-150 by year or trim, it's matched to your McGard SplineDrive lug nuts by thread: 1/2-20, M12x1.25, or M12x1.5. We don't have a confirmed vehicle coverage list for it in our fitment data.

Install and Honest Talk

This isn't a bolt-on part, it's the key for your McGard SplineDrive locking lug nuts. McGard builds it to match the SplineDrive pattern in one of three threads: 1/2-20, M12x1.25, or M12x1.5. Get the thread size wrong and the tool will not turn your locks, so check what's stamped on the lug nuts you already have before you order. The business end is a 13/16 inch hex, so it drives with a breaker bar, ratchet, or impact gun.

What else you need: McGard SplineDrive lug nuts in a matching thread size, plus a breaker bar, ratchet, or impact gun that takes a 13/16 inch hex.

Free US shipping over $99

Orders over $99 ship free by ground to the lower 48 states. Alaska, Hawaii and Canada are not included; shipping to those addresses is calculated at checkout. Some oversize or heavy parts (long-tube exhausts, bumpers, full lift kits) go freight instead of parcel: free to a commercial address with a loading dock, and residential freight delivery carries an additional charge.

When it ships

Parts ship direct from the distributor warehouse that stocks them, so dispatch timing depends on the part, not on a single cutoff. You get a confirmation with tracking as soon as it leaves, and tracking shows the delivery estimate for your address. If a part is backordered we email you an expected availability date.

Report a short shipment or shipping damage within 5 business days of delivery. For a packing error, send us the date or package code printed on the label along with the part number so we can trace it with the warehouse.
