High Tensile Strength Key Locking Inserts M3 - M24 Stainless Steel
304 For Thread Repair
Information
The bolt socket is a kind of fitting with great strength. The style
of this kind of fitting is quite peculiar, and it looks very much
like a closed spring. There are many specifications of bolt
sockets, but the main ones circulating in the market are the more
common ones. The installation method of the bolt socket is very
particular, and some tools are still needed during the installation
process.
1. It is especially suitable for the environment requiring high
strength internal threads and can be effectively anti-seismic and
anti-drawing;
2. Compared with wire screw sleeve, it can enhance the strength of
threaded hole more effectively;
3. The bolt sleeve is mainly made of stainless steel, and the
specifications also have the metric inch size;
4. Simple to use, easy to install and operate.

Advantage
- 1: threaded mounting pin sheath may effectively enhance the
fastening strength and safety threaded hole, a threaded hole
extended periods of time, improve product quality.
- 2: In some spark plugs, molds and other machinery and require
frequent removal temperature of the screw holes on the corrosive
bolt means threaded screw hole jacket may be enhanced wear
resistant-corrosion resistant.
- 3: The bolt thread sheath has a repair function. When the screw
thread of the machine's threaded hole slips due to various reasons,
use the special tap of the bolt thread sheath for tapping, install
the bolt thread sheath, and the threaded hole with the slippery
thread can be quickly repaired.
- 4: The installation tools and installation methods of the bolt
socket are simple, and the installation is simple and can save time
and improve work efficiency.
- 5: Bolt sockets are installed on machinery molds, products that
require very high threaded hole strength and fastening safety
performance on products such as aerospace industry, products,
automobile industry, and shipbuilding industry.
Application
1. Quickly and effectively repair damaged threads on a variety of
materials.
2. Enhance the thread strength on light materials, such as large
and medium-sized non-ferrous metal castings, die castings and
ductile ferrous metal base materials, as screw holes that are often
screwed in and out.
3. It is especially suitable for use in environments requiring
high-strength internal threads, with strong seismic and pull-out
resistance. High strength wire thread insert than normally used,
the base body is firmly connected with the work does not come off
the substrate in the impact or vibration environment.
4. Remedy the wrong hole and avoid reprocessing the wrong part.
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.
