Will these lug nuts fit my 6-lug wheels?

These spline lug nuts are engineered for wheels with six studs that accept 14mm x 1.50 threads and a conical seating surface. Confirm your wheel stud count and thread pitch before purchasing to ensure compatibility.

• Thread size: 14mm x 1.50 — matches metric 14mm-1.5 studs
• Seat type: conical — fits tapered wheel seats
• Designed for 6-lug wheel configurations

How durable and easy are these lug nuts to install?

GORILLA builds its lug nuts for everyday road use and aftermarket wheel applications, combining hard-wearing materials with a practical spline design that resists stripping. The kit includes a dedicated 1378SD key so you can install or remove the spline nuts with the correct tool, while dual hex options give additional wrench access when needed.

• Overall length: 2" — full engagement on stud threads
• Outside diameter: 23mm — compact profile under wheel center caps
• Hex sizes: 13/16" (21mm) and 7/8" dual hex — allows standard wrench use
• Kit contents: 24 lug nuts + 1 1378SD key — ready out of the box

What makes the spline design beneficial compared to standard lug nuts?

Spline lug nuts distribute torque across a specialized multi-groove surface, reducing the chance of rounding when compared to some exposed hex styles. The design also works well with aftermarket wheels that have recessed or thin-lip mounting holes where a traditional hex head would not seat or clear the wheel.

• Spline profile: resists stripping and improves driver grip
• Works in recessed wheel pockets where hex heads might not fit
• Black finish: improves appearance and conceals corrosion

How should I torque and maintain these lug nuts for safety?

Use a calibrated torque wrench and follow vehicle manufacturer torque specs rather than a guess. Regularly inspect lug nuts for proper torque and physical damage, and re-torque after the first 50–100 miles following installation to account for settling.

• Always follow your vehicle or wheel manufacturer's torque recommendation
• Recheck torque after initial driving period (50–100 miles)
• Replace any nut showing damage, deformation, or stripped splines
