FLYCLE Wheel Lug Nuts M12x1.5 — 20‑Pack Black 35mm Closed‑End Bulge Acorn, 19mm Hex

FLYCLE Wheel Lug Nuts (M12x1.5), 20-pack — 35mm closed-end bulge acorn lug nuts in black for aftermarket wheels.

These lug nuts are a complete 20-piece set engineered for aftermarket wheel installations that require M12x1.5 threads and a 60° conical seat. Built from SCM435 cold-forged steel with heat treatment and a corrosion-resistant black finish, the nuts offer a blend of strength, protection, and a clean appearance. The closed-end bulge acorn profile shields wheel studs from dirt and moisture while the 19mm (3/4") hex body fits common sockets, simplifying both professional shop and DIY work.

How do these lug nuts fit my wheels and vehicle?

These lug nuts are specifically sized for wheels that accept M12x1.5 studs and use a 60° conical seat. They are intended for aftermarket wheels with bulge acorn seats and are not compatible with mag seats, ball seats, or round seat designs. Always confirm your wheel seat type and thread pitch before ordering to prevent fitment issues.

• M12 x 1.5 thread pitch (12x1.5)
• 35 mm (1.4") overall length
• 60° conical (bulge acorn) seat design
• Not for use with mag, ball, or round seats

What materials and construction ensure long-term durability?

FLYCLE lug nuts use SCM435 cold-forged steel, which provides higher tensile strength than standard steel and improves resistance to bending and cracking. After forging, the parts receive heat treatment and a protective coating that enhances corrosion resistance and maintains the black finish for years of exposure to road salts and weather. The precise machining of threads ensures a secure, consistent fit on wheel studs.

• SCM435 cold-forged steel core for added strength
• Heat-treated for improved toughness
• Corrosion-resistant black finish
• Accurately machined threads for reliable engagement

How easy are these lug nuts to install and service?

The closed-end bulge acorn nuts use a standard 19mm hex, compatible with most lug wrenches and 3/4" sockets, so installation and removal are straightforward. Their closed design protects studs from contaminants, reducing maintenance and the likelihood of stud corrosion. For best results, install with the proper torque specification for your vehicle and check torque after initial road miles.

• Standard 19mm hex size fits common sockets
• Closed-end design keeps studs protected
• Quick swap for full wheels with a 20-piece set
• Recommended: follow vehicle torque specs and recheck after driving
