M6 Thread Insert Repair Key Locking Inserts With High Wearing Strength

Information

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.

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.

Installation inspection

After the wire thread insert is installed, the threaded hole tolerance zone depends on the profile manufacturing tolerance of the wire thread insert and the thread tolerance zone of the wire thread insert mounting hole. The former is controlled by the wire thread insert manufacturer, and the latter mainly depends on the tapping of the wire thread insert mounting hole. The wire precision usually forms 6H grade. When the precision is high, it can reach 5H and 4H tolerance bands. The unified thread standard is 2B and 3B. Corresponding level plug gauges can be used to detect the thread of the bottom hole.
