M3 - M24 High Tensile Strength Key Locking Inserts 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.

Specification

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.

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.
