About Open Lug Nuts
Open Lug Nuts are specialized wheel fasteners characterized by a through-hole design, meaning the nut is not capped at the end. This allows the wheel stud to pass entirely through the nut. These are essential for vehicles using extended wheel studs, a common setup in professional racing, off-roading, and heavy-duty commercial applications where standard capped lug nuts would bottom out before reaching the required torque.
At Jade Alloys, we manufacture Open Lug Nuts with precision-engineered seat types—typically conical (tapered) or ball seats—to ensure a perfect hub-centric or lug-centric fit. The open design also allows for easy visual inspection of thread engagement, a critical safety requirement on many race tracks. Our open-ended lug nuts are manufactured using high-tensile alloy and stainless steel to resist the extreme heat and shear forces generated during high-speed operation.
