The so called “double rivet” is made up of two single parts: the cap (female) and the shank (male) manufactured separately (the cap is also assembled with special machines like self piercing rivet), the shank is normally pinched on the upper part so to hold the cap before closure and can be open or closed (capped). Manufactured from metal ribbon of different materials like iron, brass, stainless steel, and plated in several galvanic finishes also free nickel in the respect of ecosystem, special coating treatments such us total varnishing (popular), top lacquered (vemar), silk-screen printing, and special processing like laser cutting. We also manufacture one model in brass material with long tubular shank (not pinched) open or closed. The correct length of the shank is very important to obtain correct closure with the cap. For some special die-cast application we manufacture a special line of shank (male) not pinched, not holed and with hollow closed cap. For riveting is intended the closure of two component by means of a rivet.
