MIKKUPPA 1/2-20 Lug Nuts 20-Piece Set — Black Closed-End Bulge Style, 60° Conical Seat

MIKKUPPA 1/2-20 lug nuts are a 20-piece set of closed-end bulge-style wheel nuts engineered to replace factory lug nuts on many Jeep and Ford models while resisting corrosion and stripping.

These lug nuts are made from heat-treated SCM435 steel and cold forged into a one-piece construction to provide consistent clamping and extended service life. Designed with a 60° conical seat and standard 1/2-20 UNF threads, this set fits a wide range of popular vehicles and aftermarket wheels. The black finish reduces glare and helps hide road grime while the closed-end design protects studs from contaminants.

Will these lug nuts fit my Jeep or Ford wheel?

They use a common 1/2-20 thread size and a 60° conical seat, matching many factory OEM and aftermarket wheels for selected model years. Fit depends on both thread pitch and seat type, so compare with one of your existing lug nuts before installing.

• Thread: 1/2-20 UNF standard
• Seat: 60° conical (bulge style)
• Hex size: 3/4" (19 mm)
• Length and diameter: ~1.4" (35 mm) long, 0.87" (22 mm) wide

How durable and corrosion-resistant are these lug nuts?

Manufactured from SCM435 steel, then cold-forged and heat-treated, they offer high tensile strength and resistance to thread stripping under normal use. The black coating and closed-end body help protect the internal stud threads from moisture and road salt to reduce corrosion over time.

• Material: SCM435 heat-treated steel for strength
• Finish: black protective coating for rust resistance
• Design: closed-end body keeps contaminants out of studs
• Testing: designed to meet common 72-hour salt spray expectations

What tools and torque settings should I use with these lug nuts?

Use a 3/4" (19 mm) socket for installation and a calibrated torque wrench for final tightening. Follow the vehicle manufacturer’s wheel torque specification rather than a generic value to avoid overstressing studs or threads.

• Socket size: 3/4" (19 mm) impact or hand socket
• Final torque: follow your vehicle manufacturer’s spec
• Tightening pattern: star/criss-cross for multi-lug wheels
• Do not use excessive impact torque for final seating

Are these lug nuts a direct replacement for OEM parts?

For many model years they are a practical aftermarket replacement when thread pitch and seat type match the vehicle’s wheel studs. Because wheel and stud configurations can vary between trims and aftermarket wheels, verify compatibility first with your vehicle or wheel manufacturer.

• Compatible examples: various Ford and Jeep models (1990s–2010s)
• Sold as a 20-piece kit to cover a full wheel set plus spares
• One-piece construction avoids separate caps or inserts
• Closed-end design prevents moisture intrusion into studs

Who is this for? Drivers who need a robust, corrosion-resistant set of replacement lug nuts for popular Jeep and Ford vehicles, or who are upgrading to aftermarket wheels that require a 1/2-20 thread with a 60° conical seat. This 20-piece, one-piece forged set suits DIY installers, professional mechanics, and off-roaders seeking stronger, longer-lasting wheel fasteners that keep studs protected from the elements. Always verify thread pitch and seat compatibility with your vehicle and use a torque wrench for safe installation.
