GAsupply 20pcs Black 12×1.5 Lug Nuts
This set mirrors the chrome version in thread size and seat angle but features a black finish achieved through electrophoresis. The black surface provides a distinct look while maintaining durability and corrosion resistance. The nuts are constructed from high-quality steel and maintain a 60-degree conical seat with a 1.38″ tall profile and a 19mm hex.
Installation considerations include ensuring wheel stud compatibility (M12x1.5) and confirming that the wheel holes accept closed-end spline tuner nuts. The included socket key simplifies on-the-spot installation and removal, and the overall design emphasizes a secure fit and long-lasting appearance.
Orion Motor Tech M14x1.5 Spline Tuner Lug Nuts
This Orion Motor Tech set includes 24 lug nuts with a 60° conical seat and a length of 2 inches, designed for 14mm x 1.5 wheels. The nuts are crafted from premium A3 steel and feature a blackened finish for corrosion resistance. A socket and usage instructions are included to help achieve a proper installation, particularly when reattaching wheels after maintenance.
Compatibility spans a wide range of vehicles that use 14mm lug studs, with a required hex wrench range of 13/16″ to 21mm. The one-piece design improves safety during installation and reduces the risk of loosening under normal driving conditions. This option is suitable for users seeking a deeper nut profile and a bold aesthetic with strong durability.
GAsupply 1/2 x 20 Chrome Lug Nuts
Designed for wheels with 1/2 inch by 20 inch studs, these lug nuts use a 60-degree conical seat and share the same 1.38 inch (35mm) length as the other GAsupply options. The chrome finish offers a bright look and robust rust resistance, with a 19mm hex for common tools. The set includes 20 nuts and a socket key to facilitate installation and removal for owners of mid-size or performance-oriented vehicles.
As with other 1/2-20 options, verify compatibility with your vehicle’s stud pattern and wheel requirements. The product emphasizes a solid one-piece construction and an anti-rust coating to withstand road exposure and varying climates.

The package includes a socket key and an installation guide, enabling safer and more accurate mounting.

Buying Guide
- Thread compatibility: Most of these lug nuts use 12×1.5 or 1/2-20 threads, with several options also available in 14×1.5. Confirm your vehicle’s wheel stud size and the seat type (60-degree conical) before buying.
- Seat type and compatibility: A conical 60-degree seat is common here. Ensure your wheels require this seat style, otherwise the nuts may not seat correctly or evenly.
- Finish and corrosion resistance: Chrome and electrophoretic black coatings offer different aesthetics and protection levels. Consider climate and exposure (salt, humidity) when choosing a finish.
- Length and tool compatibility: Most lug nuts in this category are around 1.38 inches tall with a 19mm hex. Some sets include optional longer lengths or wider socket sizes; verify that your wheel wells and impact wrenches won’t interfere with installation.
- Security and theft prevention: The include-a-key design and multi-spline patterns help deter wheel theft. If security is a priority, look for sets with robust spline configurations and included keys.
- Installation guidance: Follow torque specs from wheel manufacturers. If a socket key is supplied, use the included tool to avoid rounding the hex or damaging the studs.
- Package contents: Check whether a spare tuner key is included and if the pack size matches your wheel count (typically 4-5 lug nuts per wheel, plus an extra for redundancy).
