What is Nut Fasteners?
One of the types of a fastener is a nut with a threaded hole. Nuts which are almost always used while joining with a mating bolt to fasten various parts together.
In applications where vibration or rotation may work a nut loose, various locking mechanisms may be employed: lock washers, jam nuts, specialist adhesive thread-locking fluid such as Loctite, safety pins (split pins) or lockwire in connection with castellated nuts, nylon inserts (nyloc nut), or slightly oval-shaped threads.
