AD-Insert® self-tapping threaded insert with external and internal thread, cutting slots or cutting bores is also called self-tapping wire thread insert which was developed and exploited by Dalian andi equipment Co.,LTD.  The accuracy grade for external thread is 6H and for internal thread is 6H. The bottom hole thread will be more strength and better after installation. The hardness of insert surface can reach 450-500Hv. The insert can self tapping, there is no need to drive the bottom hole thread by screw tap, it can be screwed into directly with setting tool after drilling the pre-drill hole(For quick installation,pre-drill hole needed).It is efficient,convenient and also improve the bonding strength and abrasion resistance obviously and simplify the product design effectively, etc.Self-tapping threaded insert is applied to the following materials: Light alloys(Aluminum, magnesium, zinc and other alloy)、Cast iron、brass、bronze、 thermoplastics、 laminates、hardwoods. The insert can repair damaged internal thread, after the installation of AD-Insert®, the original screw can still be used, not only economy and artistic but also convenient and Speedy. AD-Insert® Self-tapping threaded insert is in successful application in a wide variety of different industrial sectors eg: automobile industry, the subway system, military supplies, household appliance, construction machinery, transaction machinery, electronic products, engineering plastics, advanced combination of furniture, aluminum alloy castings by a number of countries around the world.

Applications for AD-Insert® Self-tapping threaded inserts

There are two kinds of commonly styles for AD-Insert®  self-tapping threaded inserts---- cutting slots or cutting bores. AD-302 with cutting slot(and some other cutting slot Model ) is recommended for most application cases. In some materials, AD-302 creating a certain screw locking effect. If this effect is not required, we recommend using AD-307/308.  AD-307/308 (with cutting bores) was developed for materials with difficult cutting properties. This insert has a thick wall and the cutting force is distributed over three cutting edges. The version AD-307/308 is particularly suitable where minimal material thicknesses are involved. If you have special requirements, we will manufacture the products as your require. Self-tapping threaded insert is used throughout the whole of the metal and plastics processing industry. Eg: for a very long time applied to automotive industry、passenger and commercial vehicles engines 、transmissions、 aviation industry、rail car and so on. The quality has never been questioned.
