FLYCLE Wheel Lug Nuts M12x1.5 Black — 20PCS 35mm SCM435 Forged, 60° Conical Closed-End

FLYCLE Wheel Lug Nuts M12x1.5 are a 20-piece set of 35mm black closed-end bulge acorn nuts designed for aftermarket wheels, offering durable SCM435 forged steel construction, a 60° conical seat, and a standard 19mm hex for easy installation.

These lug nuts are built to replace all studs on most aftermarket wheels that require M12x1.5 threads and a bulge acorn profile. Each nut measures approximately 1.4 inches (35mm) in length and features a closed-end design to shield studs from grime and moisture. Finished in a corrosion-resistant black coating and forged from high-strength SCM435 steel with additional heat treatment, the set balances appearance with long-term durability.

Will these lug nuts fit my wheels and vehicle?

They are specifically made for aftermarket wheels that accept M12x1.5 (12x1.5) threads and a bulge acorn (60° conical) seat. They will not work with mag, ball, or round seat wheels. Always verify both your vehicle stud size and the wheel seat type before ordering.

• Thread size: M12 x 1.5 (12x1.5)
• Seat angle: 60° conical bulge acorn
• Length: ~35mm (1.4 inches)
• Not compatible with mag seats, ball seats, or round seats

How durable are these lug nuts for everyday driving and harsh conditions?

Manufactured from SCM435 cold-forged steel with additional heat treatment, these lug nuts are stronger than standard steel alternatives. Precision-machined threads and a protective coating reduce the risk of corrosion, bending, or cracking under typical driving loads and varied weather.

• Material: SCM435 cold-forged steel with heat treatment
• Coating: corrosion-resistant black finish for weather protection
• Construction: two-piece build for balanced strength
• Closed-end design protects studs from contaminants

Can I install these with standard tools and who are they suited for?

The nuts use a 19mm hex profile, compatible with most common lug wrenches, impact sockets, and handheld tools, so both DIYers and professionals can fit them quickly. Because they come in a 20-piece pack, they’re ideal for replacing all wheel lug nuts at once on a single vehicle with 4 or 5 lug wheels.

• Hex size: 19mm standard socket compatibility
• Pack size: 20 pieces for full-wheel replacement
• Installation: suitable for impact tools and manual wrenches
• Design: closed-end for clean finish and stud protection
