GAsupply 1/2-20 Black Acorn Lug Nuts 20pc — 1.38 in Tall, 60° Cone Seat, 3/4 in (19mm) Hex

These lug nuts provide a low-profile acorn (bulge) design finished in durable black electrophoresis coating. They are engineered for wheels that accept 60° cone seat fasteners and use a 3/4" (19mm) hex socket for installation. The set includes twenty pieces packaged for convenient storage and transport.

Will these lug nuts fit my wheels and studs?

Compatibility depends on the thread pitch and seat type of your vehicle's wheel studs and lug seats. These nuts are cut for 1/2"-20 threads and require a 60° conical seat; they will not fit tapered or ball-seat wheels.

• Thread size: 1/2"-20 (1/2 x 20)
• Seat type: 60° conical (cone seat)
• Height: 1.38" (35 mm) tall acorn/bulge design
• Hex: 3/4" (19 mm) socket

How durable is the black finish and steel construction?

The nuts are forged from high-quality steel and coated using an electrophoresis process that helps resist rust and fading compared with untreated metal. Proper installation and periodic inspection will extend appearance and corrosion resistance.

• Material: high-strength steel core for secure clamping
• Finish: black electrophoresis for long-lasting color retention
• Threading: cleanly cut threads for smooth installation
• Closed-end design: protects threads from dirt and moisture

What tools and torque specs do I need to install them?

Install with a 3/4" (19 mm) socket or an appropriately sized impact socket. Always follow your vehicle manufacturer’s recommended torque values to ensure proper seating and safe wheel clamping.

• Socket size: 3/4" (19 mm)
• Compatible with hand or impact tools rated for lug nuts
• Use a calibrated torque wrench for final tightening to OEM torque specs
• Check torque after initial road use per vehicle guidelines
