Manufactured from a diamond-section wire, the thread insert forms two high-precision concentric threads. One external, to be placed in a tapping, and the other internal, to screw in an element. Each Wire Thread Insert has a tang at one end for quick installation. Used in all sectors of industry, the AMECOIL® Wire Thread Insert is the essential element to secure quality assemblies. Thanks to its elasticity, the AMECOIL® Wire Thread Insert corrects the imperfections of the screw and tapping. This distributes forces over the entire assembly. Tang: used to install the thread in the tapped hole...

INSERTS TECHNOLOGICAL ADVANTAGES OF THE WIRE THREAD INSERT RESISTANCE TO PREMATURE WEAR AMECOIL® Wire Thread Inserts are usually made of stainless steel and have a higher mechanical strength than the material receiving the tapping and thus offer assemblies increased wear resistance. HOMOGENEOUS LOAD DISTRIBUTION Thanks to its elasticity, the AMECOIL® Wire Thread Insert corrects the imperfections of the screw and tapping. Thus, force distribution is spread out over the entire assembly. SCREW PULL-OFF RESISTANCE There are many advantages to using light alloys. On the other hand, they also...

TECHNICAL CHARACTERISTICS DETERMINING THE NOMINAL LENGTH OF THE AMECOIL® WIRE THREAD INSERT The table below defines the nominal length of AMECOIL® according to the receiving material and the class of the screw. This data is established for a temperature of 20°C. Screw quality Strength of the support material Rm (N/mm2)* Threaded lengths are defined to make the screw the weakest element of the assembly. These values are indications and ensure total safety in use. These lengths, as defined, can sometimes be reduced after confirmation through testing. Intermediate lengths are available upon...
