钢丝螺套

是一种新型的内螺纹紧固件，适用于螺纹连接，旋入并紧

固在被连接件之一的螺纹孔中，形成标准内螺纹，螺栓（或

螺钉）再拧入其中，又名螺纹丝套，简称丝套。它是用高

强度、高精度、表面光洁的冷轧菱形不锈钢丝精确加工而

成的一种弹簧状内外螺纹同心体，主要用于增强和保护低

强度材质的内螺纹。其原理是在螺钉和基体内螺纹之间形

成弹性连接，消除螺纹制造误差，提高连接强度。钢丝螺

套嵌入铝、镁合金、铸铁、玻璃钢、塑料等低强度的工程

材料的螺纹孔中，能形成符合国际标准的高精度内螺纹，

具有连接强度高，抗震、抗冲击和耐磨损的功能，并能分

散应力保护基体螺纹，大大延长基体的使用寿命。

钢丝螺套的性能

1、钢丝螺套应用在各种低强度材料中，能在很大程度上提高螺钉连接的耐磨损性能，避免连接螺纹的损坏。

2、因钢丝螺套有一定弹性，可使螺纹各圈上的负载分布比较均匀，消除螺钉与螺孔之间的螺距和牙型偏差，并

能吸收振动，因而提高了螺纹的连接强度和耐疲劳强度。

3、锁紧型钢丝螺套能把螺钉锁紧在螺纹孔中，在经受冲击振动时使螺钉不至于松扣，比通常锁紧装置的工艺性

能好。

4、与镶嵌钢质或铜制衬套方法相比，在同样强度条件下，可选用尺寸较小，强度较高的螺钉，这样可缩小体积，

减轻重量。

5、钢丝螺套的硬度比螺钉高，因此在与螺钉连接装拆过程中磨损小，可反复使用。据有关试验研究，钢丝螺套

抗拉强度是螺钉的 7 倍以上，因此在螺钉断裂情况下钢丝螺套也不会损坏。

Performance of steel wire thread sleeve

1. The application of steel wire screw sleeve in various low-strength materials can greatly improve the wear resistance of screw connection

and avoid the damage of connecting thread.

2. Because the steel wire screw sleeve has a certain elasticity, it can make the load distribution on each circle of the thread more uniform,

eliminate the pitch and tooth shape deviation between the screw and the screw hole, and absorb vibration, so as to improve the connection strength and fatigue strength of the thread.

3. The locking steel wire screw sleeve can lock the screw in the threaded hole and prevent the screw from loosening when subjected to

impact and vibration, which is better than the process performance of the usual locking device.

4. Compared with the method of inlaying steel or copper bushing, screws with smaller size and higher strength can be selected under the

same strength conditions, which can reduce the volume and weight.

5. The hardness of the steel wire screw sleeve is higher than that of the screw, so it has little wear in the process of connection, assembly

and disassembly with the screw and can be used repeatedly. According to relevant experimental research, the tensile strength of the steel

wire thread sleeve is more than 7 times that of the screw, so the steel wire thread sleeve will not be damaged when the screw is broken.

wire thread insert is a new type of internal thread fastener, which is suitable for threaded connection. It is screwed into and fastened in the

threaded hole of one of the connected parts to form a standard internal thread, and the bolt (or screw) is screwed into it. It is also known as

thread screw sleeve, which is referred to as thread sleeve for short. It is a spring-shaped concentric body of internal and external threads

accurately processed from cold-rolled Diamond Stainless steel wire with high strength, high precision and smooth surface. It is mainly

used to strengthen and protect internal threads of low-strength materials. The principle is to form an elastic connection between the screw

and the internal thread of the matrix, eliminate the thread manufacturing error and improve the connection strength. The steel wire screw

sleeve is embedded into the threaded hole of low-strength engineering materials such as aluminum, magnesium alloy, cast iron, glass fiber

reinforced plastics, etc., which can form a high-precision internal thread in line with international standards, has the functions of high connection strength, earthquake resistance, impact resistance and wear resistance, can disperse stress, protect the matrix thread, and greatly

prolong the service life of the matrix.

Material properties

Application of steel wire thread sleeve

1. Enhance the connection strength and improve the connection conditions. Low strength materials such as aluminum and

magnesium are selected into the steel wire screw sleeve,

which can avoid the phenomenon of sliding wire and wrong

tooth, and obtain excellent connection performance.

2. Wear resistance. It is used for parts that are often disassembled, which can greatly improve the service life of the

thread.

3. Increase the stress surface. It is used for parts requiring

strong connection force and cannot increase the diameter of

screw hole.

4. Anti loosening. Especially for spacecraft and other products

requiring high insurance coefficient.

5. Easy maintenance. Install the damaged screw hole into the

steel wire screw sleeve and continue to be used after repair to

avoid the possibility of workpiece damage reporting.

无尾螺套

Tailless Insert

"Tailless screw sleeve" is also known as "steel wire screw sleeve without mounting handle", It's a steel wire insert (threaded thread sleeve).

The steel wire screw sleeve without mounting handle has a fishhook like clamping groove at both ends. When installing the tailless screw

sleeve, use a special installation tool to directly install it without distinguishing the direction of the screw sleeve. This is unmatched by the

tailless screw sleeve, which greatly improves the work efficiency. And because the tailless screw sleeve has no mounting handle, it is omitted

In addition to the steps of installing the handle, the work efficiency is further improved, and various problems caused by the removal of the

mounting handle are completely avoided.

Tailless screw sleeve is a new thread sheath product developed on the basis of

ordinary thread sheath. Tailless screw sleeve overcomes the shortcomings of

traditional thread sheath mounting handle and low installation efficiency. The

slotted part of traditional thread sheath mounting handle can not be controlled

accurately, resulting in the phenomenon that the tail is not easy to break or too easy

to break. When removing the handle, the tail end is easy to protrude, affecting the

screw in of thread and seriously affecting the product quality, After the tail is

removed, it is difficult to clean and easy to cause retention, which will affect the

quality of the whole product in serious cases.

“无尾螺套”也称为“无安装柄钢丝螺套”，是钢丝螺套（螺

纹丝套）的一种。无安装柄钢丝螺套在二端均有一个类似

鱼钩状的卡槽，在安装无尾螺套时，使用专用的安装工具，

无需区分螺套的方向，直接安装即可，这一点是有尾螺套

无可比拟的，从而大大提高了工作效率。并且由于无尾螺

套没有安装柄，从而省掉了去除安装柄的步骤，进一步提

高工作效率，并且完全避免了由于安装柄去除所引起的各

种问题。

无尾螺套是在普通螺纹护套的基础上开发研

制的新型螺纹护套产品，无尾螺套克服传统

螺纹护套安装柄及安装效率低的缺点，传统

螺纹护套安装柄开槽部位不能控制精确，造

成尾部不易折断或过易折断的现象，去柄时

尾端易突起，影响螺纹旋入，严重影响产品质

量，尾部去除后不易清理，易造成滞留，严重

时会影响整个产品的质量。

◆◆ 无尾螺套安装比较简单，无方向性，安装便利，省去普通

有尾钢丝螺套去除安装柄的繁琐环节，节省了时间，提高效率！

◆◆ 无尾螺套安装没有去除尾柄的麻烦，极其方便。而普通有

尾钢丝螺套在安装完成后，需要把安装柄冲断，尾部去除后不

易清理，易造成滞留，严重时会影响整个产品的质量。

◆◆ 无尾钢丝螺套安装工具齐全，包括气动、电动工具、批量

安装的配套工具支架等，适合大批量的安装使用，对提高工作

效率有非常大的帮助！

The installation of tailless screw sleeve is relatively simple, non

directional and convenient. It eliminates the cumbersome link of

removing the installation handle of ordinary tailed steel wire screw

sleeve, saves time and improves efficiency!

The installation of tailless screw sleeve has no trouble to remove the

tail handle, which is extremely convenient. After the installation of

the ordinary steel wire threaded sleeve with tail, the installation

handle needs to be punched off. After the tail is removed, it is not

easy to clean up, which is easy to cause retention, and in serious

cases, it will affect the quality of the whole product.

The tailless steel wire screw sleeve installation tools are complete,

including pneumatic, electric tools, supporting tool supports for

batch installation, etc. it is suitable for mass installation and use,

which is very helpful to improve work efficiency!
