MIKKUPPA M12x1.25 Lug Nuts — 20pcs Chrome Closed-End, One-Piece 19mm Hex for Aftermarket Wheels

MIKKUPPA M12x1.25 closed-end chrome lug nuts are a 20-piece aftermarket replacement set designed for M12x1.25 threaded wheels on select Nissan and Subaru models, offering durable one-piece construction and corrosion-resistant finish.

These lug nuts are built for drivers who use aftermarket wheels with a 60° conical seat and need a reliable, finished appearance. Manufactured from cold-forged, heat-treated steel with a thick chrome-like coating, the nuts are sealed at the end to protect threads and present a clean look. They fit many common Nissan and Subaru applications when the wheel accepts M12x1.25 closed-end bulge nuts — note they are not compatible with most factory OEM wheels.

Will these lug nuts fit my vehicle and wheels?

If your car uses M12x1.25 threaded studs and aftermarket wheels that accept a 60° conical seat, these lug nuts are compatible with a wide range of Nissan and Subaru models. They are specifically offered as replacements for multiple model years of Altima, Maxima, Pathfinder, Rogue, Sentra, Outback, and Forester, but only for aftermarket wheel designs.

• M12 x 1.25 thread pitch — standard for many import vehicles
• 60° conical (taper) seat — check your wheel seat shape
• 19 mm (3/4") hex head — fits common sockets and wrenches
• Not compatible with most factory OEM wheels — aftermarket wheels only

How are these lug nuts constructed for strength and longevity?

Each nut is a single-piece, cold-forged and heat-treated steel design to maximize structural integrity and reduce risk of failure compared with two-piece styles. The finish undergoes infrared drying and a 72-hour salt spray resistance process to improve corrosion resistance and prevent the coating from peeling.

• One-piece construction for improved strength and safety
• Cold-forged and heat-treated steel core for durability
• Thick, integrated finish applied with infrared drying to resist chipping
• Closed-end design protects internal threads from moisture and debris

What are the exact dimensions and driver requirements?

These nuts are engineered to clear common aftermarket wheel lug openings while providing a secure hold. The overall length and width are sized to balance appearance and accessibility, and the hex size matches standard tooling so installation is straightforward for DIYers and pros alike.

• Length: 35.05 mm (1.38") — gives adequate thread engagement
• Width: 22 mm (0.87") — slim profile for many wheel designs
• Hex: 19 mm (3/4") — use matching socket or wrench
• Finish color: chrome/silver — polished, reflective look

How should I maintain these lug nuts to keep them performing?

Routine visual checks and periodic light cleaning will keep the finish looking new and prevent surface contamination. Avoid harsh chemicals or abrasive brushes that could damage the coating; remove and inspect for thread wear whenever rotating or replacing wheels.

• Hand-clean with mild soap and water; dry thoroughly
• Inspect threads at tire rotations to ensure secure fit
• Use a torque wrench to tighten to manufacturer-specified torque
• Avoid abrasive cleaners that may damage the integrated finish

Who is this for: These MIKKUPPA lug nuts are aimed at drivers who have aftermarket wheels with M12x1.25 studs on supported Nissan and Subaru models and want a durable, closed-end style with a chrome look. They suit enthusiasts replacing worn or mismatched nuts, garages installing aftermarket wheels, and anyone seeking a one-piece, corrosion-resistant alternative to two-piece designs. Always confirm thread pitch, seat angle, and wheel compatibility before purchase.
