This M30 castle nut is one of the most common sizes, widely used for securing trailer hubs and bearings onto trailer spindles. The M30 spindle size is versatile and applicable to various types of trailers. You will typically use a cotter pin or tang washer to secure the nut in place and prevent it from backing off while the trailer is in motion. Your axle spindle assembly will also require an M30 spindle washer.
As the last component installed onto your spindle, this M30 castle nut, once secured, allows you to install your dust cap and complete your project. Whether you have a standard or a specialized trailer axle, this M30 spindle castle nut is likely what you need to ensure a secure connection. Refer to your trailer axle manual for the proper torque specifications when tightening.
We also offer a variety of other sizes to suit your specific needs, ensuring you have the right fit for any application.
