Threaded Inserts
Threaded inserts are blocks of material with a threaded hole that are pressed or
molded into a part, usually made of a different material. The materials used for
making threaded inserts are metals such as brass and copper, and plastics such
as PVC and PTFE. There are many types of threaded inserts depending on the
material used to create them. Examples include a threaded brass insert and a
threaded plastic insert. A threaded brass insert has an internal thread and can
be used as socket head or button head machine screw. A threaded plastic insert
is a spiral ridge on the end of a pipe that enables pipes to be joined together.
T A threaded brass insert has a deep groove for maximum pull out resistance.
Knurling such as diamond, straight, and unidirectional are available in a
threaded brass insert. A threaded plastic insert is more efficient than a
threaded brass insert in the respect that it can withstand more pressure. Other
threaded inserts are commonly available.

Threaded inserts reduce risk of
cracking of installation material. A threaded rod with full thread is available
in sizes ranging from M4 to M48 in diameter with the length ranging from 1000mm
to 48000mm. A threaded round insert consists of a tube with threads around its
circumference. The maximum weight of a threaded round insert is 300Kg. A
threaded round insert is specified by tube thickness, thread, and height. Modern
threaded plastic inserts are stipulated by a measurement of the outer diameter
(OD), which is measured over the pipe thread in the case of a male pipe. To be
sure that the pipe thread will match, threads per inch (TPI) are also measured.
The inner diameter (ID) is sometimes used when buying PVC pipes. The
glass-reinforced nylon body is molded around the threaded brass insert ensuring
that the insert stays put in even the toughest conditions. A threaded tube end
is the easiest and most cost-effective way to attach mounts and glides to the
tubes and pipes commonly used to construct frames, conveyor bases and industrial
machinery. Nuts and bolts are the most common threaded fasteners. A threaded
stud is a fastener which is threaded at both ends with an unthreaded shank in
between. Failure of a threaded fastener generally occurs in one of three modes:
failure through the shank or threaded section of the fastener, threads stripping
of the external thread, or threads stripping of the internally threaded member.
Threaded inserts are designed and manufactured to meet most industry
specifications.
Threaded inserts are used in many applications. Examples include its use in
instrumentation, telecommunications, and other plastic cases assemblies.
Threaded inserts should adhere to American National Standards Institute (ANSI)
standards
