14MM X 1.5 51MM SPLINE NUT

14 mm x 1.5 Hex Spline Wheel Nut. 51 mm Length. Black coating. This professional grade closed end spline nut is precision-engineered to provide high-security wheel mounting with a durable, low-profile aesthetic. Manufactured from robust Q235 steel, this fastener features a total length of 2.00" (51 mm) and a closed-end body that completely shields the wheel stud from environmental contaminants like road salt and moisture. The component is distinguished by a 7-tooth spline drive pattern (7-R3.2) that serves as an effective theft deterrent, requiring a specialized spline key for installation and removal. A precision-machined 60-degree conical seat is integrated into the base to ensure uniform pressure distribution, maintaining a strict coaxial tolerance of less than 0.2 mm between the tapered seat and the internal threads. The exterior is treated with a black electroplated finish, providing superior corrosion resistance and a sleek look for modern wheel designs. For rapid identification, the nut includes permanent external markings indicating the M14 x 1.50 thread specification in 2.5 mm tall lettering. Order 30 for a full case.
