AUTOPTIM 1/2-20 Chrome Lug Nuts 20 Pc — 60° Tapered Seat, Closed-End SCM435 Steel

AUTOPTIM 1/2-20 chrome closed-end lug nuts (20 pieces) are aftermarket one-piece replacement nuts designed to fit many Ford wheels, offering a durable, corrosion-resistant fastener with a tapered 60° seat.

These lug nuts are engineered as one-piece, cold-forged SCM435 steel fasteners with a triple chrome finish and heat treatment to resist cracking and rust. Sized at 1/2-20 thread pitch with a 3/4" (19 mm) hex, 1.38" (35 mm) length and 0.87" (22 mm) width, they suit a wide range of aftermarket Ford wheel applications. Because they use a conical 60° seat and closed-end design, they protect studs from dirt and moisture while presenting a clean chrome appearance.

Will these lug nuts fit my Ford wheel?

They fit many Ford models that use 1/2-20 threads and a tapered 60° seat, including classic and modern vehicles listed in the compatibility section. These are aftermarket lug nuts and may not match original factory wheel seat types—verify wheel seat angle before purchasing.

• Thread: 1/2-20 standard automotive thread pitch
• Seat: 60° conical/tapered seat—match your wheel seat angle
• Hex: 3/4" (19 mm) — fits standard sockets
• Length/Width: 1.38" (35 mm) long, 0.87" (22 mm) across the widest point

How durable and corrosion-resistant are these lug nuts?

The nuts are cold-forged from SCM435 steel and heat-treated for improved strength, then finished with a triple chrome plating to resist rust and wear. The combination of one-piece construction and robust materials reduces the risk of cracking compared with many two-piece designs.

• Material: SCM435 cold-forged steel for toughness
• Finish: triple chrome plating to slow corrosion
• Design: solid one-piece body to minimize failure points
• Closed end: keeps moisture and debris away from stud tip

Are these lug nuts suitable for OEM factory wheels?

These are aftermarket lug nuts intended for wheels that accept a 60° tapered seat; they are not a universal replacement for every factory wheel. They are not compatible with 90° mag/flat/ball/radius seat wheels, so confirm your wheel seat type first.

• Not suitable for 90° mag or flat-seat wheels
• Designed for tapered 60° seat wheels only
• May differ from some original equipment specifications

Who is this for? These lug nuts are intended for car owners, restorers and wheel installers who need a rugged, chrome finished aftermarket replacement for Ford-compatible wheels that accept 1/2-20 threads and a 60° tapered seat.
