AUTOPTIM M12x1.25 Lug Nuts 20 Pcs Chrome Flat-Seat OEM Fit, Triple-Chrome Corrosion-Resistant

A complete 20-piece set of AUTOPTIM chrome one-piece lug nuts with M12 x 1.25 threading and flat 90° mag seats, built to replace OEM flat-seat lug nuts on many Nissan and Infiniti models.

These lug nuts are engineered as a direct-fit replacement when your vehicle’s wheels require flat-mag-seat hardware. Cold-forged, heat-treated steel and a triple-chrome finish create a corrosion-resistant one-piece nut designed for a precise thread fit and long service life. They are intended specifically for OEM flat-seat wheels and should not be used with conical-seat wheels or wheel caps.

How do these lug nuts match my Nissan or Infiniti wheels?

The AUTOPTIM set uses M12 x 1.25 threads and a flat 90° mag seat—dimensions that match many factory Nissan and Infiniti wheels. Confirm your wheel uses a flat seat and not a conical/tapered seat before ordering. These nuts are sized for common OEM hex sockets and wheel wells on specific model years.

• M12 x 1.25 thread pitch fits specified OEM studs
• Flat 90° mag seat designed for factory flat-seat wheels only
• 13/16" (21mm) hex head fits standard lug wrenches
• 1.47" (37mm) overall height and 1.2" (30mm) width

Will these lug nuts resist rust and wear over time?

Yes—AUTOPTIM lug nuts are cold-forged and heat-treated to increase strength and reduce cracking. The triple chrome plating provides a durable barrier against corrosion and road elements. Proper torque and installation further extend their lifespan.

• Cold-forged steel core for impact and fatigue resistance
• Heat treatment for improved hardness and durability
• Triple chrome finish for enhanced corrosion protection
• Closed-end design seals the stud thread from contaminants

Are these lug nuts easy to install and safe for everyday driving?

Installation follows the same procedure as standard lug nuts: hand-thread, then torque to the manufacturer’s specification. The one-piece construction eliminates the separation risks associated with two-piece nuts and helps maintain a secure fit between nut and stud. Always use a calibrated torque wrench and recheck torque after a short initial drive.

• One-piece design reduces cracking risk compared to two-piece alternatives
• Closed-end style protects studs from moisture and debris
• Compatible with 13/16" (21mm) socket for straightforward fitting
• Recommended to torque to vehicle OEM specifications

Verify fitment against your wheel’s seat type and stud thread to ensure correct selection.
