Simple To Use Key Locking Screw Thread Inserts M6*1 For Transmission Case

Information

The bolt sleeve is a new type of bolt sleeve product developed on the basis of the ordinary bolt sleeve. The bolt sleeve overcomes the shortcomings of the traditional bolt sleeve installation handle and low installation efficiency.

When the bolt socket is used for repair, it can be said that it has the effect of resuscitation, allowing the damaged machinery to run well, just like many machines are likely to be scrapped due to a rivet problem, but you use the bolt socket It's different, it can make the machine run well. The bolt sleeve has a smooth appearance, simple and easy to understand, does not care about the environment, and at the same time has the characteristics of no rust, to avoid the use of the machine due to rust, which will cause unnecessary losses.

Parameter

Advantages
Improve the connection conditions and increase the bearing capacity and fatigue strength of the threaded connection: the use of type threaded sleeves 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 resistance of the threaded connection 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.

The principle that the bolt sleeve enhances the connection strength of the aluminum alloy internal thread: the standard internal thread has the angle error and the pitch error of the thread processing, which leads to the small contact surface between the bolt and the thread in the base, and even point contact occurs. The uneven force of the bolt or base thread reduces the strength and fatigue life of the threaded connection.

The diameter of the plug screw sleeve in the free state is slightly larger than the diameter of the screw hole to be inserted. When assembling, the plug screw sleeve is pre-compressed by torsion force by installing the wrench thread guide ring to reduce the diameter, and the screw is screwed in with the special tap for the plug screw sleeve in advance. In a good internal screw hole, after installation, the bolt sleeve produces a spring expansion effect, is firmly fixed in the threaded hole, and will not move with the movement of the screw.

The bolt sleeve can increase the connection strength: it can be used for soft and low-strength alloy materials such as aluminum and magnesium, wood, plastic, rubber and other easily deformable and low-strength materials to avoid slippage and wrong teeth.

Repair the thread: When the threaded hole is processed incorrectly or the damaged internal threaded hole is repaired, the bolt sleeve is used as a repair tool, which can repair the parts simply and conveniently without increasing the weight and volume. Mainly used for auto parts repair, mechanical screw hole repair, engine cylinder threaded hole repair, etc.!

When the bolt socket is used for repair, it can be said that it has the effect of resuscitation, allowing the damaged machinery to run well, just like many machines are likely to be scrapped due to a rivet problem, but you use the bolt socket It's not the same, it can make the machine run very well. The bolt screw sleeve has a smooth appearance, simple and easy to understand, does not care about the environment, and at the same time has the characteristics of no rust, avoiding the use of the machine due to rust, which may cause unnecessary losses.

Loosening caused by compression of the bearing surface. Due to the large contact stress on the bearing surface of the bolt head or nut, the surface of the connected part will have a plastic ring-shaped depression. In use, if plastic deformation continues to occur (called bearing surface depression), the elongation of the bolt will decrease, the pre-tightening force in the bolt will decrease, and the nut will easily loosen and rotate.

The diameter of the free state plug screw sleeve is slightly larger than the diameter of the screw hole to be installed. When assembling, the plug screw sleeve is torsioned through the thread guide ring of the installation wrench to make its diameter smaller. Screw in the special tap for the green plug screw sleeve in advance. In the tapped inner screw hole, after installation, the bolt sleeve produces a spring expansion effect, so that it is firmly fixed in the threaded hole and will not move with the movement of the screw. The tool for removing the handle of the pin screw sleeve can be very simple. Just use a mandrel slightly smaller than the inner diameter of the screw hole of the type screw sleeve and insert it into the screw hole. Broken at the breaking groove.

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.
