Nyloc Nuts (also know as Nylon-Insert lock Nuts) are a type of lock nut that have a nylon collar (or inset) that increases the friction on the thread. They are an ideal economical option for environments that have vibration or motion that could loosen the nut. Nyloc Nuts are typically Mild steel (Class 6 or Grade 2).
Conelock Nuts are a one-piece lock nut. They have distorted threads at the top of the nut that cause them to lock into the thread. Conelock nuts are suitable for application with vibration or motion that may cause a nut to loosen and differ from Nyloc Nuts as they are typically High tensile (Class 10 or Grade 8). Also, being a one-piece steel nuts allows them to work in high temper¬ature and more harsh chemical environments.
Serrated Flange Nuts are a one-piece Nut that look similar to a Standard Hex Nut, however, they have a Flanged base with serration on its bearing surface. When the nut is tightened onto a mating surface these serrations score the surface to achieve a locking fit.
Fuji Lock Nuts have a special type of spring, called a friction ring, secured under the top face of the nut. When the nut is wound onto a thread this spring comes into contact with the threads and is pushed upward, therefore putting it under tension. This tension causes the nut threads to push against the thread that is receiv¬ing it, therefore locking the nut, and preventing loosening under vibration.
