High Strength M8 Self - Tapping Thread Insert Stainless Steel Thread Inserts
Introduction
Self tapping screw sleeve is also called self tapping braces, is a new type of fastener to strengthen thread strength, self tapping screw sleeve both inside and outside the teeth, embedded in plastic, aluminum cast iron, copper and other soft materials, can form a higher strength of the internal thread hole, self tapping screw sleeve (self tapping braces) can also have bad internal thread repair.
Self-tapping screw sleeve installation without pre-tapping thread, can directly use the installation tool to screw it into the special hole reserved for the base material, for the mother thread has broken teeth can also use the same screw and the original, economic and beautiful, for new products can increase the thread strength. Self-tapping screw sleeve (self-tapping tooth sleeve) has been widely used in automobile industry, rail car industry, shipbuilding industry, household appliances, construction machinery, business machinery, electronic products, engineering plastics, advanced composite furniture, aluminum die casting and other industries.
Use
Self-tapping inserts are self-tapping threaded inserts with slotted or perforated inserts, of which slotted self-tapping inserts are recommended for most applications. In some materials, this type of screw provides the perfect specific thread locking effect. If not, it is generally recommended to use the 307/308 model, which makes a significant breakthrough in material cutting difficulties. This product not only has a very thick wall, there are three cutting ability of the round hole scattered in the wall, 307/308 product is especially suitable for the material thickness is not too rich.

Installation method
Self-drilling screw installation method one: when the installation quantity is small, can take simple installation method, concrete is to take corresponding specification method of bolt + nut tapping screw fixed on the corresponding models of bolts, with the same nut is fixed, to make the three as a whole, and then using a wrench to screw into the bottom hole, a screw after the bolt back then.
Self-tapping screw sleeve installation method two: When installing the number is large, special tapping screw set of installation tools are available, and the first to install the self-tapping screw on special tool, tool screwing in precast a screw hole will be installed in a circle around, to ensure tools and prefabricated vertical will push again after screwing in a screw hole end face, when tapping screw end is lower than the preformed hole end is about 0.2 mm to stop screwing and reverse screw special tools. The end of the self-tapping screw sleeve installation tool is a hexagonal head, which can be connected with manual tapping wrench, electric or pneumatic tools.
