Explain in detail the steps of wire thread insert installation

The installation and disassembly of the wire thread insert can be mainly divided into five steps, here is to understand it!

1.Drill holes.

Use standard drill bits to drill holes at a depth greater than or equal to that of drilling. Be careful not to taper the hole.

2.Tap.

Use a special tap marked with the specified thread specifications of the wire thread insert to tap, the tapping length must exceed the length of the wire thread insert, all taps should be used for through holes; The precision of tapping determines the tolerance zone of the standard inner screw hole. Threaded holes can also be cleaned by cleaning; When the precision of the thread hole is high, the thread plug in the bottom hole of the special steel wire thread insert should be used for inspection.

3.Install it.

Wire thread insert installation generally adopts manual installation wrench. Put the wire thread insert into the installation wrench, so that the installation handle is embedded in the guide rod slot, rotate the installation wrench handle, so that the wire thread insert into the screw hole, and leave the 0.75~1.5P empty thread on the matrix surface. When installing a small number of wire thread inserts and coarse wire thread inserts above 14x2, it can be installed with a simple tool with T-slot or thread head. And be careful not to exert a large axial force on the wire thread insert mounting handle to prevent random buckle.

Use electric or pneumatic semi-automatic mounting wrenches for fast and reliable installation on assembly lines or when you need to install wire thread inserts quickly.

After installing the wire thread insert, the corresponding grade plug gauge can be used to check the accuracy level of the standard internal thread hole.

4.Disconnect the mounting handle.

When the hole is through, the installation handle of the wire thread insert should be removed, which is generally used for the punch to align the installation handle, and can be removed by striking with a hammer of about 200q. For coarse wire thread inserts above 18x2.5 and fine wire thread inserts above 14x1.25, bend the mounting handle up and down with needle-nose pliers to break through the slot.
