OTUAYAUTO M12x1.5 mag-seat lug nuts 20pc — direct-fit Toyota/Lexus replacement, 10.9 steel & chrome

These OTUAYAUTO M12x1.5 mag seat lug nuts (20 pieces) are a direct-fit replacement designed for many Toyota and Lexus alloy wheels, offering hardened steel strength and corrosion protection.

If your factory lug nuts are worn, stripped, or you need a full set for new aftermarket wheels, this kit supplies twenty M12x1.5 mag-seat nuts sized for common Toyota and Lexus applications. Each nut is cold-forged from 10.9 grade SCM steel, heat-treated, and finished with a three-layer chrome plating to withstand road salt, moisture and temperature extremes. The set includes a thread gauge so you can confirm the required minimum install depth, and the recommended torque spec helps ensure a safe, secure installation.

Will these lug nuts fit my Toyota or Lexus wheel?

These OTUAYAUTO nuts match vehicles and OE part numbers commonly used across Toyota and Lexus alloy wheels that require a mag (conical) seat. They replace several factory part numbers, but you should verify seat style and thread pitch before ordering.

• Thread: M12 x 1.5 with mag/conical (90°) seat
• Hex size: 13/16" (21 mm) for standard sockets
• Compatible vehicle examples: Avalon, Camry, Corolla, RAV4, Highlander, Prius, Sienna; Lexus GS series
• Cross-referenced OE numbers included for confirmation

How strong and durable are these lug nuts?

The nuts are manufactured from high-strength 10.9 grade SCM steel and undergo heat treatment to increase tensile strength and wear resistance. A triple-layer chrome finish provides added protection against rust and chemical attack, and the parts are salt-spray tested for extended durability.

• Material: 10.9 grade SCM steel, cold-forged
• Finish: three-layer chrome plating resists corrosion
• Tested to 72-hour ASTM B117 salt spray standard
• Designed for road salt, extreme cold and hot climates

What should I know about installation and torque?

Proper installation is critical: these lug nuts require a minimum of 6.5 full turns onto the stud and should be tightened to the manufacturer-recommended torque. The kit includes a thread gauge to confirm the install depth and guidance on torque values so you can achieve a safe, secure fit.

• Recommended torque: 70–80 ft·lb (follow vehicle manufacturer guidance)
• Minimum engagement: at least 6.5 full turns — thread gauge included
• Use a calibrated torque wrench for final tightening
• Intended for mag-seat alloy wheels only; not compatible with capped wheel designs

Are these lug nuts the right choice for aftermarket wheels?

These lug nuts are designed for mag-seat (conical) alloy wheels. They are suitable when your wheel specifications call for M12x1.5 mag-seat hardware, but they are not appropriate for wheels requiring capped nuts or different seat shapes.

• Designed specifically for mag/conical seat alloy wheels
• Not compatible with domed or spline-style capped wheel systems
• Confirm wheel seat type and thread pitch before purchase
• Contact support if your vehicle is not listed for additional fit checks

Who is this for: This 20-piece OTUAYAUTO lug nut set is built for drivers, mechanics, and DIYers who need a reliable, full-set replacement for Toyota and Lexus alloy wheels that use M12x1.5 mag-seat nuts. It suits anyone replacing lost or damaged factory nuts, preparing a vehicle for new wheels, or refreshing hardware to resist corrosion in harsh climates. If you’re unsure about fitment, use the included thread gauge or reach out to OTUAYAUTO support for confirmation before installing.
