AUTOPTIM M12x1.25 Lug Nuts - 20pc Chrome Flat-Seat OEM Fit, One-Piece Closed-End

AUTOPTIM M12x1.25 OEM lug nuts are a 20-piece, chrome-finished, one-piece replacement set engineered to fit Nissan and compatible OEM flat-seat wheels.

These lug nuts are built for drivers who need direct OEM-style replacements with M12 x 1.25 threads and a flat 90° mag seat. Designed as closed-end, one-piece nuts with a chrome finish, they match many Nissan and Infiniti factory wheels that require a flat seating surface. The set includes 20 lug nuts sized for a 13/16" (21mm) hex, 1.47" (37mm) height and 1.2" (30mm) width to give a secure fit without adapting the wheel bore.

Which vehicles will these lug nuts fit?

These nuts are intended for wheels that use an OEM flat (mag) seat and an M12 x 1.25 thread pitch. They commonly replace factory hardware on many Nissan models and select Infiniti vehicles; compatibility depends on the wheel seat type and stud thread size.

• Common fits: Nissan Altima (2002–2024), Maxima (1988–2023), Pathfinder (2012–2024), Rogue (2008–2023).
• Infiniti examples: Q50 (2013–2024), G37 (2008–2015), QX60 (2014–2024), QX50 (2013–2024).
• Confirm your wheel uses a flat 90° mag seat and M12x1.25 studs before purchasing.

How durable and secure are these nuts for regular driving?

The AUTOPTIM lug nuts use a cold-forged, heat-treated steel process and triple chrome plating to resist corrosion and cracking. A one-piece construction helps eliminate separation risks present in two-piece designs and maintains tight thread engagement for long-term use.

• Material/process: cold-forged steel with heat treatment for strength.
• Finish: triple chrome plating for rust resistance and appearance.
• Design: closed-end, one-piece body reduces failure points.

What are the exact dimensions and installation specifics?

These lug nuts measure 1.47" (37mm) tall with a 13/16" (21mm) hex head and 1.2" (30mm) width. They feature a closed-end body and flat 90° mag seat, so they only fit wheels designed for a flat seating surface — not conical seats or wheels with caps that require different hardware.

• Thread: M12 x 1.25; verify your vehicle studs match.
• Head size: 13/16" (21mm) hex wrench/socket required.
• Seat type: flat 90° mag seat — do not use on conical-seat wheels.

What support and warranty come with the purchase?

AUTOPTIM backs these lug nuts with customer support and a 12-month service commitment. If you encounter fitment questions or product issues, the brand provides assistance before and after sale to help resolve problems.

• Included: 20 lug nuts per set for full wheel replacement.
• Service: 12 months of customer support for fitment or product concerns.
• Tip: keep original nuts until you confirm fit and torque the replacement to manufacturer specs.

Who is this for: This 20-piece AUTOPTIM set suits owners of Nissan and compatible Infiniti models who require OEM-style flat-seat, closed-end lug nuts with M12x1.25 threads. Choose this set if you want a one-piece, chrome-finished replacement that prioritizes corrosion resistance and a tight, factory-like fit — but double-check your wheel’s seat type and stud thread before buying.
