The large notches allow for positive engagement with a castle nut wrench for proper installation and torque. The smaller notches provide a location for the end user to stake the castle nut to prevent accidental loosening. Finished in a Mil-spec manganese phosphate. Inquiry Now Request a sample

M12x1 25 Castle Nut Description

We stock a wide variety of fasteners ideal for many applications around the home, farm, business, automotive, and in industry. Most of our fasteners have a light zinc plating over steel giving a more rust resistant finish. We also sell coated and stainless products for additional rust resistance. We stock many grades of fasteners ranging from low carbon steel on up to hardened, heat treated steel. Not all fasteners are applicable for all applications so be certain to test thoroughly and get the opinion of a licensed building or certified building or structural engineer before relying on these fasteners for any situations where failure would result in damage to property or person.
