307 Three Round Hole Self tapping Screw Sleeve M8 * 1.25-9mm


The self tapping screw sleeve is generally made of carbon steel and stainless steel.
(1) Carbon steel c1215 is coated with yellow color zinc, blue zinc or blue white zinc, which is suitable for aluminum alloy,
Copper alloy, plastic and other substrates with low engineering strength.
(2) Stainless steel 303 (or stainless steel 304 and 316); It is suitable for products with high strength such as cast iron.
Advantages of using self tapping screw sleeve:
1. The self tapping thread does not need to be tapped in advance during installation, but can be directly screwed into the specific hole reserved by the base metal.
2. The self tapping screw sleeve can solve the problem of thread breakage and effectively improve the bonding strength with the base metal. For the mother thread with broken teeth, the same screw as the original can also be used, which is economical and beautiful.

Properties of steel wire insert

Steel wire screw sleeve is a new type of connection and fastening technology,

which can effectively improve the connection conditions and greatly improve the reliability of screw connection


Disassembly method edit

Insert the tip of the remover into the screw sleeve hole, press and hold the handle firmly,

and rotate it anticlockwise to remove the screw sleeve.




Wire inserts for maintenance:

Simple example: diesel engine body, all kinds of aluminum parts, lathe cutterhead, etc.

will be scrapped due to the damage of one screw hole. As long as the screw hole is re tapped and the screw sleeve is installed,

the scrapped parts will come back from the dead, and the performance will not be reduced.

Especially for large-scale expensive machine parts, it shows its economic value.
