Locking Type Threaded Insert M8 1/2 3/4 Key Locking Sleeve Insert
Introduction
Bolt screw sleeve, English is the key lock thread insert,
translated into Chinese is the screw lock sleeve, at the age of 00,
it was directly developed by the American Kane company. Since its
development, it has gone deep into aerospace, aviation and railway
machinery. , Electronics and electrical engineering and many
different fields and industries. The main feature of the product is
that there are 2-4 pre-locking keys on the external thread.
Application
1. Quickly and effectively repair damaged threads on various
materials.
2. Enhance the thread strength on light materials, such as large
and medium-sized non-ferrous metal castings, die castings and
ferrous metal base materials, which are used as screw holes that
are often screwed in and out.
3. It is especially suitable for the environment where the
high-strength internal thread is penetrated by vibration, with
strong anti-vibration and anti-drawing ability. It has higher
strength than the commonly used wire thread inserts, and is
connected to the substrate in the environment, and will not be
separated from the substrate under impact or working.
4. Wrong holes in clothes, avoiding reprocessing of wrong pieces.
Advantages
The advantages of the plug screw sleeve improve the connection
conditions, increase the bearing capacity and fatigue strength of
the threaded connection: the use of the type screw 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 thread connection Load capacity and fatigue strength.
It can be used for the connection and fastening of hard, brittle
and fragile materials such as ceramics, bakelite, and glass.
Effectively prevent fragmentation. After using the bolt sleeve,
under the same strength condition as the ordinary internal thread,
a smaller size and higher strength screw can be selected, so that a
large amount of material can be saved, weight and volume can be
reduced.

Installation method
1. Drilling hole: The drilling depth should be greater than the
length of the bolt sleeve. Note that the size of the tapping drill
is larger than the usual number.
2. Thread tapping: The size of the tapped thread should correspond
to that of the external thread of the bolt sleeve.
3. Installation: Screw the bolt sleeve into the corresponding
threaded hole, and require the bolt sleeve to be lower than the
surface of the workpiece.
4. Lock key: Use a suitable tool to press the bolt fixing key of
the bolt sleeve into the bottom hole.
Installation tool
Tools include: drill bit, wire tap, plug gauge.
Bolt screw sleeve drill bit: When drilling the threaded hole, the
drill bit of the plug screw sleeve should be larger than the
diameter of the internal thread hole of the plug screw sleeve and
smaller than the diameter of the external thread of the plug screw
sleeve.
