Castle Nut

Castle Nut

Product Code: MD-CVT-0024

The internal thread clamps the nut onto a bolt or shaft, while crown slots accept a cotter pin through a cross-hole. The example on the source page is steel with an M10 thread, approximately 18 mm outside diameter and 8 mm height. ## Construction and Use - Internal thread provides clamping. - Crown slots align with a cross-hole in the bolt or shaft. - A cotter pin mechanically limits rotation and loosening. - Used on hubs, axles, moving machinery and safety-critical assemblies. Tighten to the specified torque, align the nearest slot with the hole and insert the correct pin. Do not excessively loosen the nut merely to achieve alignment.
