Project Kics R40 Iconix Lug Nuts Black M14x1.50 (16+4 Locks / Capless)

Overview

The Project Kics R40 Iconix Lug Nuts in Black are a premium motorsport-grade lug nut system designed for high-performance street and track applications. Manufactured in Japan, the R40 Iconix series features Project Kics’ signature two-piece construction with a free-spinning seat, delivering precise wheel centering, consistent torque application, and reduced risk of wheel damage during installation.

This capless version is ideal for vehicles running extended wheel studs, making it a popular choice for track builds, aggressive street setups, and competition use. Finished in a durable black coating, these lug nuts combine functional engineering with a clean, motorsport-inspired appearance.

Key Features

The Project Kics R40 Iconix Lug Nuts are engineered to improve clamping accuracy and installation safety compared to traditional one-piece lug nuts. Key features include:

• Two-piece lug nut design with a free-spinning tapered seat for precise torque application.
• Rotating seat helps prevent galling and minimizes the risk of scratching or damaging wheels.
• Manufactured from high-strength SCM435 chromoly steel for excellent durability and load resistance.
• Capless, open-ended design accommodates extended wheel studs.
• Compact, hexagonal profile provides improved clearance for wheels with narrow lug bores.
• Black finish offers corrosion resistance and a refined motorsport look.
• Includes matching lug locks for added wheel security.

Construction & Design

The R40 Iconix Lug Nuts utilize a patented two-piece construction consisting of a hardened steel lug body and a freely rotating tapered seat. This design allows the seat to remain stationary against the wheel while the lug nut is torqued, promoting even load distribution and more accurate clamping force. Made from SCM435 chromoly steel, these lug nuts are built to withstand repeated installation cycles and the high stresses associated with track and competition use.

Installation & Fitment

The Project Kics R40 Iconix Lug Nuts are designed for direct installation using the appropriate hex drive and key adapter for the locking lugs. The open-ended, capless design makes them suitable for vehicles equipped with extended wheel studs. These lug nuts use a 60-degree tapered seat and are intended exclusively for aftermarket wheels that require tapered-seat hardware.
