About Cold Heading Self Clinching Studs

Cold heading Self Clinching Studs are a kind of studs applied to thin plates or sheet metals, also known as flower tooth studs, which are round in shape, with embossed teeth and guide grooves at the inner end. The principle is to press the embossing teeth into the preset holes of the sheet metal. Generally, the aperture of the preset holes is slightly smaller than the outer diameter of the embossing teeth of the riveting stud. Into the plate, resulting in plastic deformation around the hole, the deformation is squeezed into the guide groove, resulting in a locking effect. S series, CLS series, and SP series cold pier Pressure Riveting Studs provide a simple method for installing internal threads on precision metal sheet products, and play a reliable role in fixing. The small and delicate studs make the sheet one side The inlaid flat processing is perfect. When installing, just insert the studs into the holes of the metal plate to complete the inlaid solid function with pressure. Cold heading pressure riveting studs are also called riveting studs, self-clamping studs, which are a kind of studs applied to thin plates or sheet metals. The shape is round, with embossed teeth and guide grooves at one end. The principle is to press the embossed teeth into the preset holes of the sheet metal. Generally, the diameter of the square preset holes is slightly smaller than the embossed teeth of the riveting studs, and the riveting studs are squeezed into the plate by pressure. The periphery of the hole is plastically deformed, and the deformation is squeezed into the guide groove, thereby producing a locking effect. The riveting studs are divided into S-type fast-cutting steel riveting studs, CLS-type stainless steel riveting studs, SP-type stainless iron riveting studs and CLA-clay riveting studs made of copper and aluminum. Different use environment.

1. Appearance:

The appearance of self clinching fasteners is not allowed to have some uncoated, burnt, rough, dull, peeling, skinning conditions and obvious streaks, and pinhole pitting, black plating slag, loose passivation film, cracks, etc. are not allowed. Drops and harsh passivation marks.

2. Coating thickness:

The working life of pressure riveting fasteners in a corrosive atmosphere is proportional to its coating thickness. The generally advocated economic plating thickness is 0.00015in--0.0005in (4--12um).

Hot-dip galvanizing: the standard average thickness is 54 um (43 um for nominal diameter ≤ 3/8), and the minimum thickness is 43 um (37 um for nominal diameter ≤ 3/8).
