PRO SIZING: Suitable for M5, M6, M8, M10, and M12. This kit creates a stronger internal thread in soft metals and protects tapped threads against wear and damage.
RETHREAD FULL SET: Perform insert installations, wire thread inserts, twist drill bits, thread taps, lug breaking tools, and damaged thread repairs.
STEEL CASE: All components are contained in a convenient steel carry case.
COARSE THREAD INSERTS COIL SIZE: M5x0.8x6.7 mm, M6x1.0x8.0 mm, M8x1.25x10.8 mm, M10x1.5x13.5 mm, M12x1.75x16.3 mm.
Installation steps
1. Drilling
The drill should be drilled with the size of do in the table. The depth of the drill should be greater than or equal to L. Be careful not to drill the hole into a cone shape. Do not use a drill with severe wear. Do not drop the chips into the place that may cause damage. After drilling, the countersinking with deburring properties is allowed, and the depth of the countersinking should not exceed 0.5. Excessive countersinking is not conducive to the installation of wire thread inserts.
2. Tapping
Select the special tap taps for ST wire thread inserts with corresponding thread specifications. The length of the tapping must exceed the effective thread depth of the wire thread inserts. All through holes must be tapped. The accuracy of the tapping will directly affect the tolerance of the final standard internal thread. With, according to the accuracy of the required internal thread, the tapping method and lubrication method should be selected appropriately, and the blind hole should be tapped with appropriate force to prevent the tap from breaking. After tapping, the threaded bottom hole must be cleaned. The compressed air spray gun can be used for cleaning. The blind hole can also be cleaned with a long spray gun with radial holes, which can be cleaned from bottom to top, or can be cleaned by direct cleaning.
3. Installation
When using a manual installation tool to install the wire thread insert, put the wire thread insert into the installation wrench, insert the mounting handle into the mandrel groove and turn the handle of the installation wrench so that the wire thread insert is screwed into the threaded bottom hole through the guide thread on the installation wrench, and Leave 0.5 to 0.75 turns of empty thread away from the surface of the base body. A small amount of wire thread inserts or coarse thread thread inserts of 14*2 or more can be installed with "T" type slotting or threaded head recommended tools for installation, but be careful not to apply a large axial force on the wire thread insert mounting handle. Prevent "random deduction". Electric or pneumatic installation wrenches can be used in assembly line assembly or where quick installation of wire thread inserts is required, but they must be operated skillfully to avoid wear of thread inserts and bottom holes. After the wire thread insert is installed, the corresponding level of plug gauge can be used to test the accuracy grade of the standard internal threaded hole formed, except for the locking wire thread insert.
4. Break the mounting handle
When passing through the hole, the wire thread insert mounting handle should be broken. Generally, use a breaker to align the mounting handle and use a hammer of about 200g to remove it. For coarse thread thread inserts above 18*2.5 and 14* For threaded thread inserts with fine teeth above 1.25, the mounting handle can be removed by bending up and down with needle-nose pliers.
5. How to remove the wire thread insert
When there is a problem in the installation process of the wire screw sleeve or the wire screw sleeve needs to be taken out because of the long use of the wire screw sleeve, the unscrew should be selected, put the unscrew into the hole of the wire screw sleeve, and align the handle of the unscrew with a hammer. One click, press down the handle and rotate it in the opposite direction to take out the wire thread insert. Keep in mind that the wire thread insert should not be pulled out directly during the removal process to avoid damage to the inner threaded bottom hole.
Installation inspection
After the wire thread insert is installed, the threaded hole tolerance zone depends on the profile manufacturing tolerance of the wire thread insert and the thread tolerance zone of the wire thread insert mounting hole. The former is controlled by the wire thread insert manufacturer, and the latter mainly depends on the tapping of the wire thread insert mounting hole. The wire precision usually forms 6H grade. When the precision is high, it can reach 5H and 4H tolerance bands. The unified thread standard is 2B and 3B. Corresponding level plug gauges can be used to detect the thread of the bottom hole.
