Mardarth 20pc Radius Ball Seat Lug Nuts 12x1.5 for Honda & Acura — Chrome, Closed-End One-Piece

Mardarth 20 radius ball seat lug nuts (12x1.5) are a one-piece, closed-end replacement set engineered to fit many Honda and Acura factory alloy wheels.

If you need a full set of lug nuts that match the OE radius ball seat and thread pitch used on dozens of Honda and Acura models, this 20-piece Mardarth kit offers direct-fit simplicity, corrosion resistance, and a solid one-piece design. These lug nuts replace worn, damaged, or two-piece capped nuts with the same 12x1.5 thread, 3/4" (19mm) hex, and a 1.38" (35mm) overall length so installation is straightforward with standard sockets.

Will these lug nuts fit my Honda or Acura factory alloy wheels?

Yes — the Mardarth lug nuts are made to the OE radius ball seat and 12x1.5 thread pitch used by many Honda and Acura models, making them a direct replacement for factory alloy wheels when specifications match.

• Thread pitch: 12x1.5, hex size: 3/4" (19mm).
• Overall length: 1.38" (35mm) with radius ball seat design.
• Closed-end construction keeps contaminants out of the stud area.
• Refer to your vehicle’s lug nut spec or owner’s manual to confirm compatibility.

How durable and corrosion-resistant are these lug nuts?

These lug nuts use a one-piece solid construction to eliminate the common failure points of two-piece capped designs. They have been tested for corrosion resistance and are finished in chrome for protection and long-term appearance.

• One-piece solid build reduces rust points versus two-piece caps.
• Chrome finish improves resistance to moisture and road salts.
• Salt spray testing (72 hours) demonstrates improved longevity in corrosive conditions.
• Closed-end design prevents dirt and moisture entering the stud socket.
