OTUAYAUTO M12x1.5 Lug Nuts 24PC Black Closed-End Bulge Acorn — 19mm Hex, 10.9-Grade Strength

These are OTUAYAUTO M12x1.5 closed-end bulge acorn lug nuts (24 pieces) in black, designed to replace factory lug nuts on compatible Toyota and aftermarket wheels while providing corrosion-resistant, high-strength fastening.

Designed for drivers who need a durable, attractive lug nut set for replacement or wheel upgrades, this 24-piece kit includes M12x1.5 thread lug nuts with a 60° conical seat, 19mm hex head, and a closed-end bulge acorn profile. Each nut is cold-forged from SCM steel, heat-treated to 10.9 grade, and plated in three layers of chrome to resist rust, road chemicals, and environmental extremes. A built-in thread gauge verifies the minimum 6.5 full turns of engagement to help achieve the recommended torque specification safely.

Will these lug nuts fit my Toyota or aftermarket wheel?

These lug nuts are engineered for M12x1.5 threaded studs and a 60° conical seat, common on many Toyota models and some aftermarket wheels. They are intended as replacements for a wide range of Toyota vehicles but always confirm wheel seat type and flange limit before installation.

• Fits 1989–2023 Toyota 4Runner, 2007–2020 FJ Cruiser, and many Hiace/Hilux models.
• Compatible with various Tacoma, Tundra (aftermarket), Land Cruiser, Sequoia, and Pickup 4WD models listed in product details.
• Requires conical (60°) wheel seat and maximum 0.9" flange limit; not for capped wheels.
• If unsure, use the Confirmed Fit feature or contact support for vehicle-specific verification.

How strong and corrosion-resistant are these lug nuts?

Each lug nut is cold-forged from SCM steel and heat-treated to meet 10.9 grade strength standards, providing robust clamping force for wheel assemblies. The three-layer chrome plating is tested to withstand 72 hours in ASTM B117 salt spray conditions for improved longevity in harsh environments.

• 10.9 grade SCM steel for high tensile strength and fatigue resistance.
• Triple chrome plating reduces oxidation, road-salt damage, and chemical erosion.
• Suitable for polar cold, desert heat, and de-icing chemicals encountered in winter.
• Closed-end design helps keep threads cleaner and prevents moisture ingress.

What are the size and installation requirements?

Physical dimensions and installation guidance are provided so you can torque these lug nuts safely and accurately. The recommended torque is 70–80 ft·lbs, and the nuts include a thread gauge to confirm at least 6.5 full turns of engagement on the stud.

• Height: 1.38" (35 mm); Width: 0.87" (22 mm); 19 mm (3/4") hex.

Who is this for: This 24-piece OTUAYAUTO lug nut kit is for drivers replacing worn or damaged lug nuts on compatible Toyota models and aftermarket wheels that require M12x1.5, 60° conical-seat lug nuts. It suits owners who prioritize strength and corrosion protection—off-road enthusiasts, winter drivers, or anyone installing aftermarket wheels—who also want a clean closed-end finish and straightforward fit verification.
