MIKKUPPA 1/2-20 Lug Nuts for 60° Conical Wheels — Chrome Silver, Closed-End, 19mm Hex

MIKKUPPA 1/2-20 closed-end bulge lug nuts are durable, corrosion-resistant replacement nuts designed to fit many Jeep and other vehicle aftermarket wheels with a 60° conical seat.

These MIKKUPPA lug nuts are engineered as one-piece, cold-forged steel fasteners finished in a chrome-like silver coating that resists rust after extended salt spray testing. They are sized and shaped to replace OEM-style 1/2-20 lug nuts on a wide range of models, offering a clean finished appearance for aftermarket wheels while meeting common vehicle seat and thread standards.

Will these lug nuts fit my Jeep or aftermarket wheel?

MIKKUPPA designed these nuts to match the common 1/2-20 thread pitch and a 60° conical (bulge) seat used on many Jeep and other vehicle aftermarket wheels. Confirm your wheel’s seat type and thread size before purchase to ensure compatibility.

• Thread: 1/2-20 (standard for many light truck wheels)
• Seat: 60° conical/bulge (matches conical-seat aftermarket wheels)
• Hex: 3/4" (19mm) for standard lug wrenches or sockets
• Length: 1.38" (35.05mm) — important for wheel stud engagement

How durable and weather-resistant are these lug nuts?

These nuts undergo a 72-hour salt spray test and use an infrared drying process so the finish bonds tightly to the metal, improving resistance to oxidation and peeling. The one-piece, cold-forged and heat-treated steel construction reduces the risk of stripping and increases tensile strength compared with two-piece designs.

• Finish: thick silver/chrome-like coating applied with infrared curing
• Construction: one-piece, cold-forged, heat-treated steel for strength
• Corrosion test: pass 72-hour salt spray exposure for rust resistance
• Closed end design: protects threads from debris and moisture

What are the exact dimensions and specifications?

The specifications are provided so you can check fit and clearance for your wheel design and hub. These measurements help determine if the lug nuts will seat correctly and provide the necessary thread engagement for safe wheel mounting.

• Thread pitch: 1/2-20 UNF
• Overall length: 1.38" (35.05 mm)
• Width: 0.87" (22 mm); hex: 3/4" (19 mm)
• Seat angle: 60° conical (bulge) and closed-end cap style

Which vehicles are compatible with these lug nuts?

MIKKUPPA lists a broad range of compatible models where 1/2-20 conical-seat lug nuts are commonly used. Always verify your vehicle’s stud size and wheel seat type before installation to ensure a correct fit.

• Jeep Wrangler: 1987–2018 (many aftermarket wheels require this size)
• Jeep models: Liberty, Grand Cherokee, Cherokee across listed years
• Dodge & Ford: select Dodge Ram 1500, Nitro and many Ford models like Explorer and Mustang in the listed years

Who is this for: These MIKKUPPA lug nuts are intended for owners fitting aftermarket wheels or replacing worn OEM lug nuts who need 1/2-20 threads with a 60° conical seat. They suit DIY mechanics, auto shops, and truck and SUV drivers seeking a single-piece, rust-resistant lug nut with a clean chrome-silver look. If you prioritize solid construction, corrosion resistance, and standard 3/4" hex tooling compatibility, these lug nuts are a practical choice. Always cross-check your vehicle’s thread pitch and wheel seat design before ordering to ensure safe, proper installation.
