Heat - Resistant Stainless Steel Threaded Inserts Natural Color
Introduction
Wire thread inserts (also known as threaded sleeves, threaded sheaths, steel wire threaded sleeves, threaded wire sleeves, stainless steel threaded sleeves, etc.) are spiral coils precisely formed by a high-strength, high-precision, and smooth-surface cold-rolled diamond-shaped stainless steel wire. It is a high-precision concentric body of internal and external threads that can form standard threads. After the thread is set, a high-precision internal thread that meets international standards can be formed, and its various properties are better than those formed by tapping.
Wire thread inserts are divided into two types: ordinary type and
locking type, which can be screwed into threaded holes of metal or
non-metal materials to form a standard M with high strength, wear
resistance, high temperature resistance, shock resistance, impact
resistance, and corrosion resistance. , MJ internal thread, and can
disperse the stress, protect the base thread, can fully improve the
performance of the screw hole, extend the service life of the
parts.
Advantage
As a kind of screw sleeve fasteners, the pre-installed internal
thread has obvious advantages compared with ordinary threads:
1. Extend the service life: Because the wire thread insert is made
of stainless steel, it has high hardness, which increases the life
of the softer base thread by tens to hundreds of times; increases
its strength and avoids the phenomenon of tripping and random
buckling. occur.
2. Enhanced thread connection strength: applied to soft
low-strength alloy materials such as aluminum and magnesium, which
can effectively enhance the connection strength of the thread. The
ordinary internal thread of aluminum profile has a maximum tensile
strength of 1394N. Thread, its minimum tensile strength can reach
2100 N.
3. Enlarge the bearing surface: it can be used for thin machine parts that require a strong connection but cannot increase the diameter of the screw hole.
4. Improve the connection conditions and increase the bearing
capacity and fatigue strength of the threaded connection: Since the
wire threaded sleeve is an elastic fastener, the use of the wire
threaded sleeve can eliminate the pitch and thread deviation
between the screw and the screw hole, so that the load is evenly
distributed , Thereby improving the load-bearing capacity and
fatigue strength of the threaded connection.
5. Anti-corrosion: The characteristics of the wire thread insert
material itself and its surface is extremely smooth, and it will
not rust the mating substrate when used in harsh environments such
as humidity and corrosion, and avoid the expensive replacement of
the threaded hole due to rust and cannot be disassembled. Loss of
substrate. It can be used in chemical, aviation, military equipment
and other occasions that require high insurance coefficients.
6. Wear-resistant, heat-resistant, and corrosion-resistant: As the
surface finish of the wire thread insert is extremely high, it can
effectively reduce the friction between the internal and external
threads, and the material itself has the characteristics of high
temperature resistance and corrosion resistance. It can be used in
parts that are frequently disassembled and installed and screw
holes that are frequently rotated to extend its life.
7. Anti-vibration and anti-loosening: The special structure of the
locking screw sleeve can lock the screw in the screw hole in a
strong vibration and impact environment without loosening, and its
locking performance is better than other locking devices. It can be
used in instruments and meters, precision and precious power
equipment, and aerospace, aviation, military equipment and other
occasions that require high insurance coefficients.
8. Easy maintenance: In the case of thread processing errors or
damaged internal threads repairing, the use of wire thread inserts
can bring the base back to life, and the original screws can be
used, which is fast and economical. A simple example, such as
diesel engine body, textile parts, various aluminum parts, lathe
tool tables, etc. will be scrapped due to damage to a screw hole.
As long as it is re-tapped and the screw sleeve is installed, the
waste will come back to life.
9. Conversion: The conversion of metric ←→English ←→international standard threaded holes with wire thread inserts is very convenient, fast, economical and practical, and is suitable for any import and export products.
Application
1. It can form high-strength, wear-resistant, high-precision, interchangeable standard internal threads on mechanical parts made of metal or non-metal materials (such as aluminum, magnesium and other light alloy engineering materials). Parts, cast steel, and cast iron can improve the durability of the screws, and can prevent the screws from loosening and falling off and fatigue fracture caused by various vibrations.
2. When repairing wrongly processed or damaged internal threads, wire thread inserts (threaded sheaths) can be used as a repair method, which can be quickly and effectively repaired without increasing the weight and volume of the original product, and at the same time Can meet or exceed the original technical requirements.
3. It is very convenient and fast to use steel wire threaded sleeve (thread sheath) to convert between metric and inch.
