MIKKUPPA 1/2-20 Lug Nuts 23-Piece Set — Black Closed-End Bulge, 60° Conical Seat, 3/4" Hex

MIKKUPPA 1/2-20 lug nuts (23-piece set) are heavy-duty, closed-end bulge-style wheel nuts designed as a direct-fit replacement for many Jeep and other vehicle aftermarket wheels.

These lug nuts are built to meet the demands of rust-prone driving environments and aftermarket wheel fitments. Cold-forged steel, a durable finish applied with infrared curing, and a one-piece construction make the set resistant to corrosion, stripping, and paint flaking. The kit includes 23 pieces sized to 1/2-20 threads with a 60° conical seating angle and a 3/4" (19 mm) hex, suitable for a wide range of Jeep, Dodge, and Ford models with aftermarket wheels.

Will these lug nuts fit my Jeep or other vehicle?

If your wheels require a 1/2-20 thread with a 60° conical seat they will fit. The set is specified to match many popular Jeep models and several other vehicles when aftermarket wheel specifications call for this thread and seat type.

• Thread spec: 1/2-20
• Seat: 60° conical (bulge-style, closed end)
• Head size: 3/4" (19 mm) hex for standard sockets
• Length: 1.38" (35.05 mm); width: 0.87" (22 mm)

How durable and corrosion-resistant are these lug nuts?

MIKKUPPA applies a thick, baked finish using infrared drying so the paint bonds tightly to the metal and resists chipping. The nuts are cold-forged and heat-treated to increase tensile strength and reduce the risk of thread or head failure under load.

• Salt-spray tested over extended hours for corrosion resistance
• One-piece construction to avoid loosening issues common with multi-piece designs
• Heat-treated steel for improved strength and longevity
• Closed-end design protects threads from dirt and moisture

What are the installation and usage details I should know?

Installation uses a standard 3/4" (19 mm) socket and proper torque per your wheel manufacturer's specs. Because these are closed-end bulge lug nuts, they protect wheel studs and reduce exposure to contaminants, but always verify seat type and thread before mounting.

• Requires 3/4" (19 mm) socket for tightening
• Use a calibrated torque wrench and follow vehicle/wheel torque specs
• Confirm 60° seat compatibility with your aftermarket wheels
• Closed end prevents debris ingress into threads

What comes in the box and what warranty/support is offered?

The set contains 23 black lug nuts sized and finished for aftermarket wheel compatibility. MIKKUPPA provides customer support and a limited 12-month assistance commitment to address fitment or quality concerns.

• 23-piece kit of 1/2-20 closed-end bulge lug nuts
• Black baked finish with infrared-cured coating
• 12 months of brand support for fit or quality issues
• One-piece construction—no separate caps or adapters included

Who is this set for? Drivers upgrading to aftermarket wheels or replacing worn lug nuts on Jeeps, Dodge trucks, Ford models, and other vehicles that require 1/2-20 bulge-style nuts will find this MIKKUPPA set useful. It’s aimed at owners who need durable, corrosion-resistant hardware with a reliable finish and those who prefer closed-end nuts to protect wheel studs. Always confirm thread size and seat angle before purchase to ensure safe, correct fitment.
