Effectively Fixed Internal Thread

- Apr 24, 2018 -

The riveting nut column, also called pressure riveting stud or nut column, is a kind of fastener applied to sheet metal, thin plate, chassis, and cabinet. The shape of the riveting nut column is hexagonal at one end and cylindrical at the other end. There is an undercut in the middle between the edge and the cylinder. The internal thread is internal thread. The hex head is pressed into the preset hole of the sheet through the press (the hole diameter of the preset hole is generally slightly larger than the outer diameter of the cylinder of the riveting screw). The periphery of the hole is plastically deformed, and the deformed portion is squeezed into the undercut groove of the riveting nut column so that the riveting nut column is riveted to the thin plate so as to form an effectively fixed internal thread on the thin plate.

Pressure riveting studs can be divided into two kinds: through hole type pressure riveting studs and blind hole pressure riveting studs. It is noteworthy that the through hole riveting studs are half through holes after a certain length of riveting studs. The standard of teeth. The riveting nut column is divided into quick-cut steel through-hole riveting nut column SO type, stainless steel through-hole riveting nut column SOS type, quick-cutting steel blind-hole riveting nut column BSO type and stainless steel blind from the material and internal thread form. Hole pressure rivet nut column BSOS four types, respectively, applied to different environments. The riveting nut column does not have a specific national standard. Early manufacturers came from the United States and gradually formed today's industry standards after being introduced into China.
