What is the self-tapping screw, self-tapping screw sleeve
Also called self-tapping threaded sleeve crowns of the self-tapping, a new strengthening of the 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.
Do not have to attack pre-sets of installation of the self-tapping screw thread installation tools can be used directly to screw into the hole reserved by the parent material, female thread collapse tooth can also use the same as the original screws, economic and beautiful, for new products can increase the thread strength.
Self-tapping screw (self-attack crowns) is now widely used in the automotive industry, the rail car industry, shipbuilding industry, household appliances, construction equipment, business machines, electronic products, engineering plastics, advanced combination of furniture and other industries.
Self-tapping screw set of advantages:
Ability to self-tapping screw sets with self-tapping thread, the parent material does not have to pre-tapping, saving costs.
Contact surfaces and finished to withstand high tensile strength, and product design can use a lower strength materials.
Already wear or collapse of the teeth of the parent thread repair role, using self-tapping threaded sleeve can continue to use the same screws.
Vibration resistance, to prevent loosening.
Demonstrated gap with the base metal, base metal if it contains air bubbles have a good air tightness.
Self-tapping screw set installation is simple, rapid, only an assembly tools, low cost, almost all yield. |
