MIKKUPPA M12x1.5 Mag-Seat Lug Nuts for Toyota – 20pc Chrome, Closed-End, Cold-Forged

MIKKUPPA M12x1.5 mag seat lug nuts are a 20-piece chrome-finished replacement set engineered to fit Toyota mag-seat alloy wheels and restore secure, OEM-style wheel fastening.

These lug nuts are designed as direct-fit replacements for many Toyota models equipped with mag-seat (conical/mag) factory alloy wheels. Manufactured from cold-forged, heat-treated steel and finished with multi-layer plating, the kit aims to deliver corrosion resistance and reliable clamping strength for everyday driving. The nuts are closed-end for protection against dirt and moisture and sized to match Toyota’s M12x1.5 specification.

Will these lug nuts fit my Toyota model and stock alloy wheels?

They are intended for Toyota applications that require a mag (magnetic/conical) seat and an M12x1.5 thread. Check your vehicle’s wheel stud size and seat type before purchasing; they are not universal for tapered or ball-seat wheels.

• Compatible with Toyota Camry (1983–2024) and Corolla (2003–2024)
• Fits RAV4 (1994–2024), Highlander (2001–2024), Sienna (1998–2024)
• Also fits Avalon, Matrix, Venza, Prius model ranges listed in product details
• Requires mag-seat OEM alloy wheels — not for aftermarket wheels with different seat types

What are the physical specs and finish of these lug nuts?

Each nut uses an M12x1.5 thread with a 13/16" (21 mm) hex drive for standard socket compatibility. They are closed-end mag-seat style with a chrome/silver plated surface to resist oxidation and preserve appearance over time.

• Thread: M12 x 1.5
• Hex size: 13/16" (21 mm)
• Overall height: 1.46" (37 mm); base width: 1.2" (30 mm)
• Finish: multi-layer nickel/copper/chrome plating for corrosion resistance

How durable and safe are these lug nuts for daily driving?

These lug nuts are cold-forged and heat-treated to improve tensile strength, then plated with multiple layers to limit rust and wear. They are sold as an OEM-style replacement and built to meet common factory specifications, making them suitable for routine use when installed and torqued to manufacturer recommendations.

• Cold-forged steel construction for improved toughness
• Triple-layer plating to slow corrosion and maintain finish
• Closed-end design helps keep threads clean from road debris
• Packaged as 20 nuts — enough for most wheel change and spares

What comes in the package and are there any installation notes?

The set includes 20 lug nuts, offering complete replacement coverage and a few extras for spares. For safe installation, tighten the nuts by hand to seat them first and finish torque with a torque wrench — avoid power tools to prevent over-tightening or damaging the plating.

• Contents: 20 closed-end mag-seat lug nuts
• Installation tip: hand-start each nut, then torque to the vehicle manufacturer’s spec
• Do not use electric impact tools to avoid thread or surface damage
• MIKKUPPA provides 12 months of customer support for fit or quality questions
