SUS303 Self - Tapping Wire Thread Insert M2 M3 M4 3/4 For Wood
Insert
Use
On some materials, this threaded sleeve provides the perfect
specific thread lock effect. If it still does not work, it is
generally recommended to use the 307/308 type. The 307/308 type has
made a major breakthrough in the difficulty of material cutting.
This product not only has a thick wall, but also has three circular
holes with cutting ability scattered on the wall. The 307/308
product is especially suitable for the case where the material
thickness is not too generous.
Generally, there is no need to install self-tapping screw sleeves
for products that are not required, but some important connection
parts need to be installed due to high tensile requirements or
special design. Self-tapping screw sleeves are produced and tested
in strict accordance with the ISO/TS16949 quality system. The
application of self-tapping screw sleeves almost runs through the
entire metal and plastic processing industry. The products have
been used in the automotive industry, civil and commercial vehicle
engines, transmissions, and aviation for a long time. Industry,
rail car industry, etc., its quality has never been questioned.

Introduction
302 type is the most widely used in all self tapping screw sleeve
products. Its two slots not only play the role of cutting, but also
have a little inward locking force.
Model 303 is a thin-walled version of 302 series, which is mainly
used in some plastic or light alloy that cannot have thick wall.
For difficult to cut materials, it has larger wall thickness,
shallower but sharper external thread. The screw sleeve uses three
round holes as cutting edge. The difference between 307 and 308 is
the length of the insert.

Installation Precautions
1. For different processing materials, refer to the drilling size
specifications for pre-drilling processing. When the hardness of
the corresponding material is relatively high, please slightly
increase the bottom hole in the drilling range.
2. The slotted end of the screw sleeve is downward, and the
self-tapping screw sleeve is completely installed into the front
end of the tool, and it must be in vertical contact with the work
piece. When installing (1～2 pitch), please make sure to align the
bottom hole and never tilt. When you find that it is tilted, please
do not reverse the tool and readjust it before using it. After
entering 1/3~1/2, you cannot start again. In addition, please do
not rotate the tool in the opposite direction, otherwise it will
cause the product to malfunction.
3. The self-tapping screw set should be at least 1mm lower than the
surface of the part after being fitted.
