About this item

  • GOOD CONNECTION PERFORMANCE: Steel thread inserts used in low-strength materials such as aluminum and can avoid thread damage and obtain good connection performance, thereby improving connection strength and improving connection conditions.
  • WEAR : Used for parts that need to be disassembled frequently, which can greatly improve the service life and wear of the thread.
  • ELASTICITY: Due to a certain elasticity, the thread insert can make the load distribution on each thread uniform, eliminate the pitch and tooth deviation between the screw and the screw hole, and absorb vibration, thereby improving the thread connection strength and fatigue strength.
  • PREVENT LOOSENING: Wire sleeve thread repair insert can prevent loosening of screws, especially for products requiring high safety factor.
  • EASY TO MAINTAIN: Insert the thread into a damaged screw hole, and then use the screw hole normally to avoid the loss of the workpiece.

How to Use:

1. Drilling

Use the drill bit of the size listed in the parameter table of the wire thread insert to drill the hole. Be careful not to drill the hole into a cone shape. The chips generated by the drill hole must be blown out with compressed air. After drilling, the counterbore should not exceed the depth of 0.4 pitch. Too large counterbore is not conducive to the screwing of the wire thread insert.

2. Tapping

Use special taps for wire thread inserts to tap. The depth of the tapping must exceed the installation length of the thread inserts. After tapping, use a compressed air spray gun to blow out the debris. When the thread accuracy is high, check the tapped bottom hole with a special bottom hole plug gauge for wire thread inserts.

3. Installation

Put the wire screw sleeve into the installation wrench (figure 5 on the right), insert the wire screw sleeve installation tail handle into the guide rod groove of the installation wrench, and turn the handle of the installation wrench to screw the wire screw sleeve into the screw hole. For installation of M14x2 or more phase thread thread inserts, you can use the "T" type slotting simple tool to install; Note: During the installation and screwing process of the thread inserts, there should be no pressing in the vertical direction to prevent jumping teeth. The correct method is slowly screw in the direction of thread rotation.

4. Remove the handle (break off the mounting handle) Use a breaker to break the mounting handle. Use about 200g of coconut to hit the breaker instantly, and the handle can be removed. Do not use the mounting wrench to rotate in the opposite direction. Do not break the mounting handle. This situation is easy. As a result, the tail shank was broken and the wire was pulled out.

5. Unscrew

When installation problems occur during the installation of the wire thread insert (such as jumping teeth), the thread insert needs to be removed, and a special sleeve remover should be used to remove the wire thread insert.

Box has multiple sizes and hi quality. Use them in cylinders to repair pulled threads in aluminium . Really decent stuff, as we torque these down between 18 to 22 foot pounds.
