AUTOPTIM M12x1.5 OEM Lug Nuts — 20-Pc Chrome Set for Honda Radius-Seat Wheels, One-Piece Durable Finish

AUTOPTIM M12x1.5 OEM lug nuts are a set of 20 chrome, one-piece replacement lug nuts engineered to fit Honda and compatible factory-style wheels with an M12 x 1.5 thread and radius seat.

These replacement lug nuts are made to match common Honda factory dimensions while offering corrosion resistance and a one-piece design that reduces failure points. Finished in triple chrome over cold-forged, heat-treated steel, they balance factory appearance with long-term durability. They include detachable plastic washers and are intended for radius-seat wheels—confirm your wheel seat type before buying.

Will these lug nuts fit my Honda wheels?

They are designed for wheels that use an M12 x 1.5 thread and a radius (also called acorn or OEM-style) seat. Fitment covers many Honda and Acura models, but fit depends on the wheel seat angle and stud engagement depth.

• Thread: M12 x 1.5
• Overall height: 1.38" (35 mm)
• Base diameter: 0.90" (23 mm)
• Seat type: radius seat (not for tapered 60° or mag 90° seats)

How are these lug nuts constructed for strength and longevity?

Each nut is manufactured in a one-piece design, cold-forged and heat-treated to reduce the risk of cracking that can occur with multi-piece nuts. A triple chrome finish provides corrosion resistance and a factory-ready shine for years of exposure to weather and road salt.

• One-piece construction to avoid separation and cracking
• Cold-forged, heat-treated steel for tensile strength
• Triple chrome plating for rust resistance and a mirror look

What does the set include and how do I install them?

The kit contains 20 chrome lug nuts and detachable plastic washers to protect the wheel finish. Installation uses a 3/4" hex socket and should follow manufacturer torque specs—over-tightening can damage studs or threads.

• Quantity: 20 lug nuts per set
• Tool size: 3/4" (19 mm) hex socket recommended
• Includes detachable plastic washers to prevent wheel scratching

Are these safe for highway driving and long-term use?

The one-piece, precision-threaded design and heat-treated steel aim to provide reliable clamping and reduce failure risk under normal driving conditions. Regular inspection and correct torqueing are essential for ongoing safety.

• Precision thread fit minimizes loosening
• Durable materials and plating help resist corrosion-related failures
• Follow torque recommendations and inspect periodically for wear

Who is this for: Drivers who own Honda or compatible wheels with a radius seat and need an OEM-style replacement that looks factory-correct but improves durability. This set suits DIY enthusiasts, mechanics, and anyone replacing lost or damaged lug nuts on models like the Honda Civic, Accord, HR-V, Element, and compatible Acura vehicles. Confirm thread pitch and seat type on your wheels before purchasing to ensure correct fitment. AUTOPTIM offers 12 months of customer support for questions before or after purchase.
