What is the self-tapping braces, self-attack crowns what is
Braces are also called self-tapping self-tapping threaded sleeve is a new enhanced thread-strength fasteners, self tapping screw sleeve both inside and outside the tooth pattern, embedded in plastic, aluminum, cast iron, copper and other soft materials can be formed higher strength of the internal thread hole, self-tapping screw sleeve (self-tapping braces) to repair or has bad internal thread.
Braces to install self-tapping without prior tapping, can be used directly to install the tool to screw into the hole reserved by the parent material for the collapse of the teeth the mother thread can use the same as the original screws, economic and beautiful, for new products can increase the thread strength.
Self-attack crowns (self-tapping braces) are now widely used in the automotive industry, the rail car industry, shipbuilding industry, household appliances, construction equipment, business machines, electronic products, engineering plastics, high-level combination of furniture and other industries.
Self-tapping braces Material:
The use of the material self-tapping braces are generally two kinds of carbon steel and stainless steel
Carbon steel, plated, color zinc; suitable for aluminum, copper alloy, plastic and other engineering strength of the lower substrate.
Stainless steel; suitable for use on cast iron and high strength products.
Since the attack capped with steel wire spiral set difference:
Both within and outside the dental pattern, and an overall high-strength self-tapping just a tool can be quick and easy assembly device tightness and shock resistance
The original screws or the approximate length of the screw can still be used with a commercially ready-tapping machine can perform automated assembly
Almost any place or a small space can also perform repair
High surface hardness had not occurred to lower total cost for secondary collapse dental devices
Inside and outside the teeth, the wire spring type to be non-standard special size wire tapping tapping
Should be used with a variety of special tools to use the device program complicated Wait a minute is no such function was not significant
The screw length by the sheath length limited by the need to design more complex mechanical
