Hexagonal stainless steel rivet nuts, pull nuts, and instant pull nuts are used for fastening various metal sheet and pipe manufacturing applications. They are widely used in the assembly of electromechanical and light industrial products such as automobiles, aviation, railways, refrigeration, elevators, switches, instruments, furniture, and decoration. They were developed to address the shortcomings of welded nuts on thin metal sheets and thin tubes, such as fusibility, deformation of the base material during welding, and thread stripping during tapping. They eliminate the need for tapping or welding nuts, resulting in secure, efficient, and easy-to-use riveting.
If a product's nut needs to be installed externally, and the internal space is too narrow to accommodate the ram of a sub-riveting machine, and methods such as rivet extraction cannot meet the required strength requirements, neither press riveting nor expansion riveting are feasible. Pull rivets are essential. They are suitable for fastening sheet and pipes of various thicknesses (0.5mm-6mm). Using a pneumatic or manual pull rivet gun, they can secure the nut in one go, providing a convenient and secure connection. They replace traditional welded nuts, addressing the shortcomings of welded nuts on thin metal sheets and thin tubes, such as fusibility and uneven welding.
Rivet nuts are mainly used in non-structural load-bearing bolt connections, such as the connection of interior parts of railway passenger cars, highway passenger cars, ships, etc. The improved rivet nuts that can prevent self-spin are superior to aircraft pallet nuts. Their advantages are lighter weight, no need to rivet the pallet nuts in advance, and they can still be used even if there is no operating space on the back of the substrate.
