Self Tapping Thread Insert 302 Nut M3 - M12 For Various Materials
Introduction
As a self-tapping threaded sleeve with slotted or perforated
self-tapping threaded insert, wherein the self-tapping screw-type
slotted sleeve is recommended for most applications. On some
materials, this threaded sleeve provides the perfect specific
thread lock function. 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 wide.
Self-tapping screws are generally classified iron teeth, finger F
is a wood-type teeth, usually countersunk head, generally refers to
a type A A dental tip end banquet i.e., B-type B generally refers
teeth, i.e. flat end banquet.

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.

Application
It is widely used in aerospace components, locomotive, high-voltage
electrical appliances, automotive power, wind power, nuclear power,
communication and electrical industries. It is used in aluminum,
magnesium, copper alloy, plastic, plexiglass, plywood, steel, cast
steel and cast iron to make it more tough and firm.
