14MM X 1.5 1.38IN SPLINE NUT

14 mm x 1.5 Closed End Passenger Spline Acorn Nut. 1.38" Length. This professional grade closed end passenger spline acorn nut is specifically engineered for secure wheel mounting and long term performance. Manufactured from durable Q235 steel, each fastener measures 1.38" (35 mm) in total length and features a precision 7-tooth spline drive pattern. Unlike other models in this series, the A-LM107-14 utilizes a 7-tooth configuration combined with an enlarged flange outer diameter of 23 mm to ensure maximum surface contact and torque distribution. The design includes a precision machined 60-degree conical seat with a strict coaxial tolerance of less than 0.2 mm between the tapered seat and internal threads to maintain perfect centering. The exterior is treated with a high quality chroming surface treatment to provide exceptional resistance against rust and environmental corrosion. For precise technician reference, the nut features permanent external markings indicating the M14 x 1.5 thread specification in 2.5 mm tall lettering.
