dynofit M12x1.5 6-Spline Locking Lug Nut Set — 20pc Closed-End, Corrosion-Resistant Alloy

These dynofit lug nuts are made from cold-forged alloy steel, finished with an electrophoretic coating, and supplied with a dual-hex socket key so you can replace factory nuts or secure aftermarket wheels that use M12x1.5 threads. The one-piece construction and 6-spline lock design add an extra layer of theft deterrence while the closed-end style helps shield threads from grime and corrosion.

Which cars and wheels are compatible with this dynofit 12x1.5 set?

This set fits vehicles that use M12x1.5 wheel studs with a 60° conical (tapered) seat and a 19mm hex size. It is commonly compatible with many Honda and Chevrolet models and most aftermarket wheels designed for those thread/pitch and seat specifications. Always verify your vehicle’s lug nut seat type and thread pitch before ordering.

• Thread pitch: M12 x 1.5 (metric)
• Seat type: 60° conical/tapered
• Hex size: 19mm (3/4") and 21mm (13/16") on supplied socket key
• Quantity: 20 lug nuts (for 4 vehicles with 5-lug wheels or spares)

How do the locking 6-spline design and closed-end shape protect my wheels?

The 6-spline internal pattern requires the included matching key to install or remove the nuts, making casual theft more difficult without the proper tool. The closed-end configuration prevents road salt and debris from reaching the stud thread, which helps prolong component life and maintain proper torque seating over time.

• 6-spline lock prevents removal with generic tools
• Closed end shields stud threads from contamination
• Electrophoretic finish increases corrosion resistance
• Cold-forged alloy steel for higher tensile strength

What are the exact specifications and installation notes?

Each nut measures about 1.38" (35mm) overall length with a 20mm outer diameter. Hand tools or a torque wrench are recommended for final tightening; impact tools are discouraged to avoid damage. The set ships with a two-size socket key for convenience during installation or emergency removal.

• Overall length: 35mm (1.38")
• Outer diameter: 20mm
• Included key: 19mm (3/4") and 21mm (13/16") hex options
• Installation tip: use hand wrench and torque to manufacturer spec

Who is this for? The dynofit 12x1.5 6-spline lug nut set is ideal for owners of cars and aftermarket wheels that require M12x1.5 threads and a 60° conical seat, drivers who want added theft resistance without complex hardware, and anyone replacing worn or corroded lug nuts. It’s suited to DIY mechanics, tuners fitting aftermarket rims, and fleet managers seeking durable, corrosion-resistant wheel fasteners.
