Industrial fasteners are connective mechanisms used
to join and secure materials together. Fasteners can be broken down into
two types: threaded fasteners and non-threaded fasteners. Industrial
fasteners are available in different forms such as metal fasteners, plastic
fasteners, metric
fasteners or composite industrial fasteners. Some industrial
fasteners, such as locking thread industrial fasteners, have multiple
components. Self-locking industrial fasteners accessories include cotter
pins, lock wires and clips and require extra labor time for installation.
Other fasters, like frictional locking industrial fasteners, require
increased torque to install the industrial fasteners. These industrial
fasteners are not reusable and require greater loads than typically necessary
to be effective when applied to some joints.
Threaded industrial fasteners, such as nuts, bolts and screws contain
spiral ridges called threads, which aid in the attachment of the threaded
industrial fasteners. Continuous-thread studs are used for flange bolting
with two nuts applied and are threaded from end to end. Tap-end studs
have a short thread on one end for screwing into a tapped hole and a
longer threaded end called a nut-end, which may have either a chamfered
or round point. Double-end studs have equal-length threads on both ends
with chamfered points and are used for flange bolting or other applications
in which torching from both ends is necessary. Other threaded industrial
fasteners include sheet metal industrial fasteners, riveting industrial
fasteners, and clinching industrial fasteners types.
Non-threaded fasteners, such as rivet industrial fasteners, ring industrial
fasteners and pin industrial fasteners, do not contain threads. These
fasteners can be quickly assembled and removed from components and do
not need extra industrial fastening hardware. Bind fastener rivets, or
pop industrial fastener rivets, are inserted into a pre-drilled hole
and a rivet gun pulls on a headed-shaft that passes through the rivet.
The shaft breaks or "pops," leaving a bulge on the head of
the rivet, which holds the two parts together. Dowel pins can be straight,
tapered, rolled or grooved and provide perfect alignment, holding parts
in absolute relation to one another. Most retaining rings need a groove
to seal them into position and are stamped both internally and externally.
While some of them may be self-locking, both kinds are used to keep parts
from slipping or sliding apart.
There are more than 500,000 types of fasteners and metric fasteners available.
Applications are limitless; almost every item contains a fastening mechanism
to connect parts together. There are furniture industrial fasteners,
electronic equipment industrial fasteners, appliance industrial fasteners,
aerospace fasteners, automobile industrial fasteners and building structure
industrial fasteners just to mention a few. The selection of industrial
fasteners depends upon the type of the industrial fasteners, size of
the industrial fasteners, shape of the industrial fasteners and weight
of the materials being connected. There is a wide variety of head options
for industrial fasteners, which determine how the industrial fasteners
will sit against the material. The type of head also affects the required
length of the industrial fasteners. Environmental conditions, such as
temperature, moisture and ultraviolet radiation, to which the industrial
fasteners may be subjected, are also factors. Chemicals or other corrosive
substances to which the industrial fasteners may be exposed and decorative
properties required of the industrial fasteners must also be considered.
Types of Industrial Fasteners Including: Metric Fasteners,
Industrial Fasteners, Stainless Fasteners, Plastic Fasteners, and Specialty
Fasteners.
- are screws and bolts used in the assembly of aircraft.
- are fasteners that are installed by pulling
the end of the mandrel or stem, resulting in the breakage of the stem
at the breaker groove and leaving the head of the stem within the fastener
body.
- have received heat treatments resulting in
a fastener surface that is harder than the core.
- follow the metric system instead of the English
system. Conversion charts are available from most fastener manufacturers.
- comply with U.S. federal and military specifications
for fastening mechanisms.
- work together to form a common fastening mechanism.
A bolt is an external threaded fastener that consists of a partially
threaded shaft, which penetrates the object connected, and is held
in place by nuts, metal blocks with complementary internal threads
that grasp the upper shaft of the bolt and secure the work piece together.
- function as latching mechanisms on doors and compartments
and join panels on cabinets, workstations and appliances.
- provide an alternative to
traditional metal fasteners, although they have low resistance to
UV radiation. Plastic fasteners
are common components of children's toys, as well as appliances
and automobiles.
- are non-threaded fasteners commonly used on door
hinges and pulleys, as well as furniture and electronic equipment.
Pins are
placed into aligned holes in the joined parts, forming a secure connection.
- are external threaded fasteners consisting of a spiral-shaped
shaft and a head. The shaft fits into a work piece and is held
in place by the head.
- are available through many fastener manufacturers.
Specialty fasteners can be custom-made according to specific
customer requirements.
- are strong, corrosion and heat resistant
mechanisms that are useful in countless applications in the
automotive, electronic, medical, marine and construction industries.
- have received heat
treatments, resulting in consistent hardness throughout the entire
fastener.
Common Terms Related to Industrial Fasteners, Metric Fasteners,
Industrial Fasteners, Stainless Fasteners, Plastic Fasteners, and
Specialty Fasteners
-
The supporting part of industrial fasteners through which industrial fasteners is loaded.
- Industrial fasteners accessible on only one side.
- The point on blind fasteners that can not be accessed.
- Referring to blind fasteners, it is the part of the rivet
that expands into the material. In reference to threaded fasteners, it
is the part of the industrial fastener that is not threaded and is located under
the head.
- A head of a threaded fastener that has a low, rounded
top surface and a bearing surface, which is large and flat.
- The ability of industrial fasteners to hold together previously
separated materials.
- A feature of
industrial fasteners that allows them to
fill irregular, slotted, oversized or misaligned holes.
- The condition in which two
industrial fastener surfaces share
the same center.
- A head that when installed will sit flush to
the surface.
- The permanent deformation of
industrial fasteners resulting from
the application of stress and heat.
- The degree of difference between the centers of
the surface of industrial fasteners at different points.
- A fracture resistance ability of a fastener
during subjection to stress variations.
- A head with a rounded top, cylindrical-shaped
sides and a bearing surface that is flat.
- The thickness of the assembled materials or parts for which
the fastener was designed to secure.
- The materials that
industrial fasteners have connected together.
- A measurement indicating the length between the beginning
of a thread and the point at which the thread reaches its fullest size.
- The widest point of a screw thread.
- The narrowest point of a screw thread.
- The distance between two threads
on industrial fasteners.
- The part of industrial fasteners bodies between the head and the
threaded portion.
- Components designed to protect fragile materials at contact
points between the material and the industrial fasteners.
- The process of creating threads by cutting into
the metal blank, as opposed to rolling.
- A cold forming process involving the creation
of industrial threads through the plastic deformation of a metal blank. The process,
which produces rolled threads that have higher strength and abrasion
resistance than threads constructed through cutting, involves the application
of pressure, which stretches the metal past its elastic limit into the
required profile
