8-32 Inset Nut Self Tapping Threaded Inserts Stainless Steel Material With Hole
Structure
Self-tapping threaded insert are also called self-tapping threaded sleeves. They are a new type of fastener that enhances the thread strength. Self-tapping threaded insert have tooth patterns on the inside and outside. They are embedded in softer materials such as plastic, aluminum alloy cast iron, and copper to form a relatively High-strength internal threaded holes, self-tapping thread insert can also repair damaged internal threads.
Features
(1) The diameter of the wire thread insert in the free state is slightly larger than the diameter of the screw hole into which it is inserted. When assembling, the wire thread insert is subjected to the torque of a special wrench to make its diameter smaller and enter the threaded hole that has been tapped with a special tap. After being installed, the steel wire threaded sleeve produces a spring expansion effect, making it firmly fixed in the threaded hole, and will never come out with the screw out.
(2) Increase the load-bearing capacity and fatigue strength of the threaded connection: the wire threaded sleeve makes the screw and the internal threaded hole for the installation of the wire threaded sleeve form an elastic connection, thus eliminating the screw moment and tooth form half-angle error between the internal and external threads. The load on each thread is evenly distributed at the specified length, thereby strengthening the internal thread and damping vibration, so the fatigue strength of the threaded connection of the parts can be improved.
Use
Self-tapping threaded inserts are self-tapping threaded inserts with slots or holes. Slotted threaded threaded inserts are 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 very 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.
