A nut is a type of fastener with a threaded
hole. Nuts are almost always used in conjunction
with a mating bolt to fasten multiple parts together. The two partners are kept together by a combination
of their threads, friction with slight elastic deformation, a slight stretching of the bolt,
and compression of the parts to be held together. In this video, I will going to discuss about
Different types of Nuts and their applications. Acorn Nuts or Cap Nuts. An acorn nut or cap nut, also referred to
as crown hex nut, blind nut, domed cap nut, or dome nut , is a nut that has a domed end
on one side. When used together with a threaded fastener
with an external male thread, the domed end encloses the external thread of the threaded
fastener, either to protect the thread itself or to protect nearby objects from contact
with the thread. In addition, the dome gives a more finished
appearance. Flange Nuts. A flange nut is a nut that has a wide flange
at one end that acts as an integrated, non-spinning washer. This serves to distribute the pressure of
the nut over the part being secured, reducing the chance of damage to the part and making
it less likely to loosen as a result of an uneven fastening surface. Castle Nuts. A castellated nut, sometimes referred to as
a castle nut, is a nut Used with cotter pins to prevent loosening, a castellated nut, also
called a castle or slotted nut, is a not with slots cut into the top. Used in low-torque applications such as holding
a wheel bearing in place. Coupling Nuts. A coupling nut, also known as extension nut,
is a threaded fastener for joining two male threads, most commonly a threaded rod, but
also pipes. . The outside of the fastener is a hex so
it can be driven with a wrench. Hex Nuts. Hex Nut is the most common hexagonal fastener
with internal threads that screws on to the shank of a bolt or a hex cap screw. Keps-K Lock Nuts. Also known as a keps nut, a k-nut or a washer
nut, a keps-k lock nut has an attached free spinning lock washer. Keps nuts are designed to make assembly more
convenient. T-Nuts. A t-nut or tee nut is used to fasten wood,
particle or composite board leaving a flush surface. A long thin body with a flange at one end
resembles a T in profile. T-nuts often have 3 or 4 prongs that sink
into the surface providing better retention. Square Nuts. A square nut is a four-sided nut. Compared to standard hex nuts, square nuts
have a greater surface in contact with the part being fastened, and therefore provide
greater resistance to loosening. They are also much less likely to become rounded-off
after repeated loosening or tightening cycles. Square nuts are typically mated with square-headed
bolts. Knurled Thumb Nuts. A knurled head thumb nut or thumb nut has
a knurled outside surface rather than a hex, which facilitates tightening by hand. Often used in decorative finishes or applications. Nylon Hex Lock Nuts. A low profile lock nut is hex shaped, internally
threaded with a nylon insert. The nylon material prevents loosening from
vibration and cross threads to stop the nut from backing off of the fastener. Wing Nuts. Wing nuts are threaded nuts with wings on
each side of the body allowing for manual turning and installation. Easy hand assembly and used when the nut needs
to be removed often. Dear Sir, Thanks for watching the video. More update please subscribes our channel
