Product Specification

304SS Tangless Thread Inserts Helicoils DIN8140 Without Tail Handle

Information

"Tailless screw sleeve" is also called "steel screw sleeve without mounting handle", which is a kind of wire screw sleeve (threaded wire sleeve).
There is a fish hook-like slot on both ends of the non-mounting shank wire threaded sleeve. When installing the tailless threaded sleeve, use a special installation tool without distinguishing the direction of the threaded sleeve. You can install it directly. The tail screw sleeve is incomparable, which greatly improves the work efficiency. In addition, since the tailless screw sleeve has no mounting handle, the step of removing the mounting handle is omitted, the work efficiency is further improved, and various problems caused by the removal of the mounting handle are completely avoided.

The difference between tailless screw sleeve and tail screw sleeve

◆ Difference 1:
The installation of the tailless screw sleeve is relatively simple, non-directional, and convenient to install, eliminating the cumbersome links of removing the installation handle of the ordinary tailed wire screw sleeve.
Save time and improve efficiency!

◆Difference 2:
The installation of the tailless screw sleeve is extremely convenient without the trouble of removing the tail handle. After the installation of the ordinary tail wire threaded sleeve is completed, the installation handle needs to be broken. 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 entire product.

◆Difference 3:
There are complete installation tools for tailless wire thread inserts, including pneumatic tools, electric tools, and supporting tool brackets for batch installation, which are suitable for mass installation and use, and are very helpful to improve work efficiency!

Advantage

1 Convenient installation, cost saving, self-tapping screw sleeve installation does not need to use tap tapping, self-tapping screw sleeve has the function of self-tapping thread
2 Strengthen the strength of the screw hole and improve the quality of the product. The self-tapping screw sleeve is a high-strength fastener with high strength and hardness, which can protect the screw hole and prevent the thread from being damaged.
3 has three shapes: slot type, three round hole type
4 There are two kinds of materials: stainless steel and carbon steel. 5 can be used for thread repair. When the thread is damaged, the thread can be repaired with a self-tapping screw sleeve. The screw hole after the repair can also be used with the original bolt;
6 Low cost, easy to install, only one tool is needed for installation
7 Installation will not produce defective products

Paramter

Application

1. It can form high-strength, wear-resistant, high-precision, interchangeable standard internal threads on mechanical parts made of metal or non-metal materials (such as aluminum, magnesium and other light alloy engineering materials). Parts, cast steel, and cast iron can improve the durability of the screws, and can prevent the screws from loosening and falling off and fatigue fracture caused by various vibrations.

Typical applications: high-voltage switchgear, hydraulic machinery, welding equipment, tobacco machinery, microwave communications, auto parts, air separation equipment, coal machines, power machinery, textile and chemical fiber machinery and furniture, etc.

2. When repairing wrongly processed or damaged internal threads, wire thread inserts (threaded sheaths) can be used as a repair method, which can be quickly and effectively repaired without increasing the weight and volume of the original product, and at the same time Can meet or exceed the original technical requirements.

Typical application: Repair of threaded holes of various parts after tripping, such as: repair of threaded holes of injection molding machine template. Repair of threaded holes in engine cylinders, etc.

3. It is very convenient and fast to use steel wire threaded sleeve (thread sheath) to convert between metric and inch.

Installation method

1. Put the tailless screw sleeve on the top of the shaft of the tool (there is no direction requirement, they are bidirectional)

2. Adjust the tailless screw sleeve to the appropriate screw hole, unscrew the hand tool (electric tool), it can automatically install and exit the installation tool, and then you can install the screw). Exit the tool and install the screw.
