QuadBoss Spline Lug Nuts 12x1.25 - Black

Upgrade your ATV or UTV wheel hardware with QuadBoss Spline Lug Nuts in 12x1.25 thread pitch. Built for riders who demand reliability and a clean, aggressive look, these black spline lug nuts are engineered to handle the torque and vibration of off-road riding without loosening or corroding over time.

Why Choose Spline Lug Nuts for Your ATV or UTV?

Standard hex lug nuts are prone to rounding off under heavy off-road use. Spline-style lug nuts use a multi-point drive pattern that requires a specific spline socket, adding a layer of tamper resistance while distributing torque more evenly across the fastener. The result is a more secure wheel mount that holds up to the hard hits, rock impacts, and mud riding that define real off-road use.
