14MM X 2 51MM SPLINE NUT

14 mm x 2 Hex Spline Wheel Nut. 51 mm Length. Black coating. This industrial strength closed end spline nut is precision-engineered for heavy-duty vehicle security and high-performance wheel mounting. Manufactured from robust Q235 steel, this fastener measures exactly 2.00" (51 mm) in total length and features a closed-end body that completely shields the wheel stud from environmental contaminants, moisture, and road salt. The component is distinguished by a specialized 7-tooth spline drive pattern (7-R3.2) that serves as a reliable theft deterrent, requiring a specific spline key for installation. A precision-machined 60-degree conical seat ensures maximum contact and uniform pressure distribution against the wheel surface, maintaining a strict coaxial tolerance of less than 0.2 mm between the tapered seat and the M14 x 2.00 internal threads. The exterior is treated with a premium black electroplated finish for superior resistance against rust and corrosion while providing a sleek, modern aesthetic. For rapid identification by maintenance technicians, the nut includes permanent external markings indicating the thread specification in 2.5 mm tall lettering. Order 30 for a full box.
