Reeauto M12x1.5 Mag Flat Seat Lug Nuts 24pc Chrome 13/16 21mm 10.9-Grade Steel

Reeauto M12x1.5 mag flat seat lug nuts are a 24-piece, one-piece, heat-treated steel replacement set engineered to fit vehicles using 12x1.5 threads with a mag flat seat and 13/16" (21mm) hex sockets.

If your vehicle uses mag flat seats and 12x1.5 thread pitch lug nuts, this full set from Reeauto provides a direct, durable replacement. These lug nuts are one-piece, closed-end, chrome-finished components built from 10.9-grade heat-treated steel so they resist wear and maintain torque integrity. The set includes 24 identical nuts sized 1.46" x 1.18" (OAL often noted as 1.5" / 37mm), compatible with many Toyota and Lexus models and cross-referenced to common OEM part numbers.

Will these lug nuts fit my vehicle?

Fitment depends on thread pitch, seat type, and wheel well clearance. These nuts use M12x1.5 threads and a mag flat seat, so they match wheels and hubs that require that combination. Confirm your vehicle’s OEM specifications or existing lug nut measurements before ordering.

• Thread pitch: 12x1.5 (metric)
• Seat type: mag flat seat
• Hex drive: 13/16" (21mm)
• Overall length: approximately 1.46"–1.5" (37mm closed end)

How durable and secure are Reeauto one-piece lug nuts?

These are manufactured from 10.9-grade heat-treated steel, offering greater tensile strength than lower-grade alloys. The one-piece construction eliminates the failure point found in some cap-style OEM nuts, reducing the risk of separation under normal driving loads. The closed-end design also helps keep out debris and moisture.

• Material: 10.9-grade heat-treated steel for improved strength
• Construction: one-piece body to prevent cap separation
• Finish: chrome for corrosion resistance and a polished look
• Design: closed end to protect threads from contaminants

Are these compatible with OEM replacement part numbers?

Reeauto cross-references several common OEM part numbers to simplify matching. If your vehicle lists one of the referenced part numbers, these lug nuts are intended as direct replacements. Always verify thread and seat specifications and test fit one lug nut before installing the full set.

• Common replacement references included: 90942-01058, 90080-17036
• Also cross-referenced: 90942-01095, 19204273, 611-167
• Best practice: confirm thread pitch and seat type before full installation

What tools and torque specifications are needed?

These lug nuts use a 13/16" (21mm) hex socket for installation and removal. Use a properly calibrated torque wrench and follow your vehicle manufacturer’s torque recommendation to ensure secure seating without over-tightening. If you lack a torque specification, consult the vehicle manual or a professional technician.

• Drive size: 13/16" (21mm) socket required
• Use a torque wrench for accurate final tightening
• Follow the vehicle manufacturer’s lug torque values
• Inspect threads and seats for damage before installation

Who is this for? These Reeauto M12x1.5 mag flat seat lug nuts are intended for owners, mechanics, and wheel shops seeking a robust, one-piece, closed-end replacement for vehicles that require 12x1.5 threaded, mag flat seat hardware. They’re a practical option for drivers of compatible Toyota and Lexus models (including many Tacoma, 4Runner, Corolla, and GX470 configurations) who want a durable steel lug nut with a chrome finish and direct OEM cross-reference compatibility. If you need a full 24-piece set to service multiple wheels or keep spares on hand, this set provides consistent sizing and finish across all pieces.
