About This Part
Fine pitch M24 x 0.5 threads are what let a lock nut clamp precisely without whipping past the shoulder. This nut runs the thread at 6H class, plug gauged, with Ø25.5 and Ø31 plus or minus 0.05 diameters, 14.5 plus or minus 0.05 length, and a 60 degree locating slot that indexes against the mating part.
Face runout is held at 0.01 A, which is the number that decides whether the nut seats square on the bearing or encoder face. 7075-T6 keeps the nut strong at 0.02 kg, and black anodize handles wear and appearance with the thread class protected.
Inspection is the M24 x 0.5 6H plug gauge, micrometer and CMM on face runout, and appearance.

Common Questions
Why 0.5 pitch instead of standard M24?
Fine pitch gives finer axial adjustment per turn and resists loosening under vibration, which is exactly what a lock nut on an encoder stack is for.
What does 0.01 face runout buy?
A nut that seats square. Tilted lock nuts preload bearings unevenly and walk loose; the runout callout is the prevention.
