GAsupply M12x1.5 Black Lug Nuts 20pcs + Key — 35mm Tall 60° Conical, 6-Spline Anti-Theft Finish

GAsupply 12x1.5 Black Lug Nuts are a 20-piece set of 6-spline, 35mm tall conical-seat wheel nuts with a matching key, built to replace or upgrade M12x1.5 studs while improving wheel appearance and durability.

These lug nuts are engineered for wheels that use M12x1.5 threads and a 60° conical seat. The one-piece steel construction and electrophoresis black finish resist corrosion and fading, while the included spline key fits the 6-spline pattern for secure installation and anti-theft convenience. This product combines a practical fitment specification with an aesthetic blackout look to modernize a vehicle’s wheelset.

Will these lug nuts fit my car or aftermarket wheels?

Compatibility depends on two key measurements: thread pitch and seat type. Confirm your vehicle’s stud specification is M12x1.5 (often noted as 12x1.5) and that your wheels accept a 60° conical (acorn) seat. If both match, these lug nuts will thread on properly and seat securely.

• Thread size: 12x1.5 (M12x1.5)
• Seat type: 60° conical (acorn)
• Lug nut height: 35mm (1.38")
• Hex/driver requirement: 19mm (3/4") wrench for the hex portion

How do these lug nuts perform in terms of durability and finish?

Each lug nut is machined as a solid one-piece steel unit and finished using electrophoresis, which improves adhesion and resists chipping better than basic paint. Threads are cleaned and cut to provide smooth installation with minimal cross-thread risk, and the black finish reduces visible corrosion and maintains a factory-like appearance longer.

• Material: high-strength steel one-piece construction
• Finish: electrophoresis black coating for long-lasting color
• Thread condition: clear, clean-cut threads for easier mounting
• Corrosion resistance: improved vs. basic painted nuts

What comes in the box and how do I install them safely?

The set includes 20 spline-drive acorn lug nuts plus a matching spline key socket for installation and removal. Use the spline key to engage the nuts, then tighten to the vehicle manufacturer’s recommended torque with a 19mm socket or torque wrench to ensure safe wheel mounting. Always tighten in the recommended star pattern and recheck torque after the first 50–100 miles.

• Included: 20 spline lug nuts + 1 spline key socket tool
• Recommended tool: 19mm (3/4") torque wrench for final torque
• Installation tip: tighten in a star pattern and retorque after initial driving
• Packaging: compact, protective retail box for storage

Can these lug nuts improve my vehicle’s look without affecting safety?

Yes—when matched to the correct stud and seat type, these lug nuts provide a sleek, blacked-out aesthetic while maintaining proper mechanical engagement. They are designed to meet fitment and torque requirements; however, they do not change wheel alignment, tire performance, or load ratings. Always follow torque specs and periodic inspections for continued safety.

• Visual upgrade: blackout finish for a modern wheel appearance
• Function: secure 60° seat engagement with proper torque
• Maintenance: inspect threads and coating during routine tire service
• Do not use if seat or thread type mismatches the wheel or stud
