The ET shank design is the defining feature of the 125001MZ5. The 5mm guiding shank with a 14.7mm outer diameter allows the lug nut to pass through the wheel's lug hole bore and engage the stud with additional thread engagement compared to a standard conical nut — making it especially valuable when pairing OEM wheel studs with aftermarket wheels that have deeper lug bore pockets. The closed-end design protects threads from contamination and provides a clean, finished appearance.

Installation Note: A standard 19mm hex socket (not splined) is required for installation. Confirm the wheel's lug hole outer diameter is sufficient to accommodate the socket during torquing. Sold individually — order the quantity needed to complete your wheel installation.
