A DIN 985 Nyloc nut, made from A4 (Grade 316) "marine-grade" stainless steel, is a six-sided prevailing torque lock nut featuring a non-metallic (nylon) insert. Its primary purpose is to resist loosening caused by vibration in highly corrosive environments, such as marine or chemical processing applications, by creating a friction-based locking mechanism on the bolt threads.
