Creating threaded slots at the end of round and square tubes has always been a compelling need for manufacturers—at least, until now. Crown-Nut by Specialinsert is the revolutionary insert that solves these fastening problems on said types of semi-finished products while providing excellent locking performance. Available in a wide range of shapes and sizes, Crown-Nut offers numerous advantages. Let's take a look at the main ones. - Wide diameter tolerances: thanks to the elasticity of the crowns, it is possible to use the same item for tubes of different sizes. This also prevents the inner diameter to shrink during and after welding operations.- Innovative design: these inserts do not damage or alter the shape of the material.- Ease of assembly: Crown-Nut inserts are press-fit and do not require costly welding and staking processes.For more information and technical details, download Specialinsert's Crown-Nut catalog at this link.
