JiiinMiiin M12x1.5 Chrome 20-Piece 6-Spline Lug Nut Set with Dual-Hex Socket Key, 60° Conical Seat

JiiinMiiin M12x1.5 20-piece chrome lug nut set with a 6-spline locking design and included socket key secures aftermarket wheels with a 60° conical seat.

This lug nut kit is built for drivers who want a tougher, theft-deterrent alternative to cap-style nuts for aftermarket wheels that accept M12x1.5 threads and a 60° taper. Each one-piece nut is CNC-machined from high-strength steel, treated with multiple chrome layers and anti-rust oil, and paired with a dual-hex socket key so you can install and remove the set safely without compromising wheel fitment.

Will these nuts fit my wheels and studs?

They fit wheels and studs that use an M12x1.5 thread pitch and a 60° (conical) seating angle. Check your wheel manufacturer specifications or measure an existing nut to confirm compatibility before ordering.

• Thread: M12 x 1.5 (metric fine)
• Seat type: 60° conical (tapered) seat
• Wheel application: aftermarket wheels with matching seat and thread
• Quantity: 20 nuts, suitable for most passenger cars and some light trucks

How durable and corrosion-resistant are these lug nuts?

The nuts are CNC-machined from high-strength steel and finished with a multi-layer chrome coating plus added anti-rust oil to extend life and resist corrosion better than single-layer painted options.

• One-piece steel construction resists stripping and deformation
• Four layers of chrome plating for improved longevity
• Anti-rust oil applied to slow oxidation in wet environments
• Better durability than lightweight cap-style or thin-plated nuts

How does the 6-spline locking system improve security?

The 6-spline locking pattern requires the supplied socket key to remove the nuts. Without the matching key, standard wrenches cannot torque them down or back off easily, discouraging opportunistic theft while still allowing proper maintenance.

• 6-spline internal pattern prevents simple socket removal
• Included socket key has 19mm and 21mm hex faces for convenience
• One-piece nuts cannot be converted into cap-style, theft-prone parts
• Designed for workshop removal with proper tools to avoid damage

What comes in the package and how is it organized?

The set is supplied with everything needed to outfit four wheels plus spare nuts: 20 lug nuts and one dual-hex socket key, all packed in a protective padded box to keep components separated during shipping and storage.

• 20 chrome M12x1.5 lug nuts (one-piece, 6-spline internal)
• 1 socket key with 19mm and 21mm hex options
• Padded box with separated compartments to prevent scratches
• Ready for immediate installation with appropriate torque tools

Who is this for? Drivers and wheel installers who need a robust, secure set of lug nuts for aftermarket wheels that accept M12x1.5 threads and a 60° tapered seat will find this JiiinMiiin kit practical. It’s suited to people who prioritize theft deterrence, long-term corrosion resistance, and a one-piece machined design over lightweight cap-style fittings. If you’re unsure about fitment, verify your wheel’s thread pitch and seat angle or consult a technician before purchase.
