RHI Automotive Black Spline Lug Nut

RHI Automotive spline lug nuts are wheel lug nuts with a spline drive design. They give a clean, factory-style look and add a layer of wheel security. The grooved spline drive needs the matching key to install and remove, so the nuts are harder to take off than standard hex lug nuts. This product line is also known as spline drive lug nuts or tuner lug nuts, and it suits many aftermarket and factory wheels.

Key Features:

• 18-point AntiWear design: The acorn-style lug nut has 18 points of contact. This spreads torque over a larger contact area than a traditional 6-point lug nut.
• 1045 carbon steel construction: The nuts are cold forged and heat treated to 10.9-grade hardness for strength and durability.
• Protective coating: A Nanoshield coating helps resist rust, corrosion and wear.
• Two-piece construction: The nuts have a separate outer shell for a clean appearance.
• Spline drive: The nuts are installed and removed with the spline drive key (adapter) that comes with the kit.

RHI engineers its lug nuts to meet or exceed OEM quality standards. Pick the variant that matches your wheel's thread size, seat type and lug count.
