AUTOPTIM M12x1.5 Lug Nuts — 24 Pc Black Conical 60° Seat, Closed-End Steel

These lug nuts are engineered as one-piece, cold-forged steel hardware finished in black zinc to resist corrosion and provide a snug fit for compatible aftermarket wheel applications. Intended for vehicles that accept M12 x 1.5 threads and a 60° tapered seat, the set covers a broad range of Toyota trucks and SUVs but is not intended for factory wheels with non-conical seat types.

Will these lug nuts fit my Toyota?

These AUTOPTIM lug nuts are made with M12 x 1.5 threads and a 60° tapered (conical) seat, which is the common standard for many aftermarket wheels on Toyota models. They are listed as replacements for numerous model years of 4Runner, Tacoma, Tundra, and FJ Cruiser when the wheel accepts conical-seat M12 nuts.

• Thread: M12 x 1.5
• Seat: 60° tapered/conical
• Selected vehicle compatibility: 1984–2023 4Runner, 1995–2022 Tacoma, 2000–2006 Tundra, 2007–2013 FJ Cruiser
• Not compatible with flat, ball, radius, or 90° mag-seat factory wheels

How are these lug nuts constructed and why does that matter?

The AUTOPTIM lug nuts use a one-piece design formed by cold forging and then heat-treated for strength. One-piece construction eliminates the joint between components found in two-piece designs, reducing the chance of cracking or loosening under load.

• Material: heat-treated steel for improved durability
• Finish: black zinc plating to slow corrosion
• Design: closed-end, one-piece body to protect threads and improve longevity
• Hex size: 3/4" (19 mm) for standard socket use

What are the physical dimensions and practical features?

Each nut measures approximately 1.38" (35 mm) in length with a 0.87" (22 mm) hex width and is tapered to seat securely in conical-lipped wheels. The closed-end shape keeps debris and moisture out of the fastener, preserving the wheel stud and thread engagement over time.

• Length: ~35 mm (1.38")
• Hex: 19 mm (3/4") for common lug sockets
• Width at widest point: ~22 mm (0.87")
• Package count: 24 nuts — enough for two vehicles or a full wheel set plus spares

Are these safe to use and what support comes with purchase?

These nuts are manufactured to be robust and corrosion-resistant, but because they are aftermarket parts, confirm seat type and thread size before installation. AUTOPTIM offers a 12-month customer service period for assistance with fitment or product questions.

• Manufacturing: cold-forged and heat-treated to reduce cracking
• Corrosion resistance: black zinc finish
• Support: 12 months customer service from AUTOPTIM
• Installation: use proper torque and verify wheel seat compatibility

Who is this for: Drivers and DIYers who need a reliable aftermarket set of M12 x 1.5 conical lug nuts in black for compatible Toyota trucks and SUVs, or for anyone replacing worn or missing lug hardware on aftermarket wheels that require a 60° tapered seat. Confirm your wheel’s seat style and thread specification before ordering to ensure correct fitment.
