SS 304 Nylock Nuts are a premium option for applications requiring safe, vibration-resistant fastening, and Stainless Bolt Industries is happy to provide them. These nuts are made of AISI 304 stainless steel, which offers remarkable resistance to corrosion, particularly in areas that are exposed to moisture and saltwater. The particular characteristic of NYLOCK Nuts is their nylon insert, which generates a powerful locking action that restricts the nut from loosening due to vibration or stress. This makes them particularly effective in industries where fasteners are subjected to continually movement or mechanical stress.
Our SS 304 NYLOCK Nuts are compatible with a wide range of bolts and assemblies since they are available in a variety of sizes, thread types, and finishes.
Stainless Bolt Industries produces the SS 304 Nylock Nut, a very dependable self-locking nut with an incorporated nylon insert that is composed of AISI 304 stainless steel. This nut looks like a regular hex nut from the outside, but it has a unique nylon ring (usually white or blue) sitting in the upper part of the thread. The secret to its self-locking mechanism is the nylon ring, which raises resistance against the mating bolt thread and helps keep the nut from coming free from movement or vibration. Stainless steel is characterized by its smooth, metallic silver sheen and six-sided hexagonal body. When looking into the nut, it is easy to see that the nylon insert is located in the inside of the top area.
