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

Designed for vehicles that use 1/2"-20 studs and a 60° conical seat, this pack replaces factory or aftermarket lug nuts with a closed-end, bulge acorn profile in a durable black finish. Constructed from quality steel and finished via electrophoresis, the nuts resist rust and maintain a clean appearance while providing the correct seat geometry to match conical-seat wheel studs.

Which vehicles and wheels are compatible with these 1/2x20 lug nuts?

These lug nuts are intended for wheels that accept 1/2"-20 threads and a 60° conical seat. They are not universal — confirm your wheel stud thread size and seat type before buying to ensure a correct, safe fit.

• Thread: 1/2"-20 (also written 1/2 x 20)
• Seat type: 60° conical (cone) seat
• Hex size: 3/4" (19 mm) for tool engagement
• Height: 1.38" (35 mm) — short/stock acorn tuner profile

How durable is the black finish and the steel construction?

GAsupply applies an electrophoretic coating for a consistent, adherent black surface that resists chipping and corrosion better than simple paint. The steel core ensures the threads remain strong and the closed-end design helps keep contaminants out of the nut.

• Material: high-quality steel for strength and thread integrity
• Finish: electrophoresis-based black coating for improved corrosion resistance
• Closed-end design: reduces moisture and dirt ingress into the threads
• Clear, clean-cut threads for easier installation and removal

What is the correct way to install these lug nuts?

Installation requires matching the lug nut to your stud thread and seat geometry, using a 3/4" (19 mm) socket or wrench, and torquing to your vehicle manufacturer’s specification. Hand-start each nut to ensure proper thread engagement before applying torque with a calibrated torque wrench.

• Start each nut by hand to avoid cross-threading
• Use a 3/4" (19 mm) socket or wrench for tightening
• Finish with a torque wrench to vehicle-specified torque values
• Check torque after the first 50–100 miles of driving
