Slotted Self tapping thread insert for mental

Self-tapping Thread Inserts is a kind of fastener with internal and external thread and cutting hole or groove. There are two kinds of materials: carbon steel and stainless steel. The surface of carbon steel is galvanized (yellow zinc, color zinc and blue zinc), and stainless steel is the natural color of metal.

    3 hole Type Self tapping thread insert for mental

    307/308 self-tapping thread insert are made of stainless steel and carbon steel two types, its basic application is very wide, mainly reflected in the thread protection, texture strong and texture repair and so on several aspects. 307/308 self-tapping thread insert are a kind of high-strength type of threaded fasteners, its inside and outside the screw threads, the three garden holes on it are used for tapping threads when installing, because 307/308 self-tapping thread insert are installed without the use of taps tapping threads, they themselves have the characteristics of self-tapping threads. Use a tap to tap threads, they themselves have the characteristics of self-tapping threads.

    Attention during installation
    1. For different processing materials, refer to the drilling size specification for pre-drilling processing. When the hardness of the corresponding material is high, please slightly increase the bottom hole within the drilling range.
    2. With the slotted end of the socket down, install the self-tapping thread insert completely into the front of the tool, and it should be in vertical contact with the work piece. When installing (1 to 2 pitches), please make sure that the bottom hole is aligned and never tilt. If tilting is detected, do not reverse the tool and readjust before using. After 1/3 to 1/2 of the way in, do not start again. In addition, please do not reverse the rotation of the tool, otherwise it will cause product failure.
    3. The self-tapping thread insert should be at least 1mm below the surface of the part after assembly.

    Application of Self tapping threaded inserts

    Self-tapping thread insert are thread inserts with slotted or open holes, with slotted thread insert being recommended for most applications. In some materials, this type of insert provides perfect specific thread locking. If this is not possible, the Type 307/308 is generally recommended and represents a major breakthrough in the area of difficult material cutting. With a very thick wall and three holes with cutting capacity dispersed in the wall, Type 307/308 is particularly suitable for use in materials with less generous thicknesses.
