General Notes on Blind Rivets
A blind rivet is a mechanical fastener capable of joining workpieces together from one side of the assembly only. Below are selection of commentaries on the product details, and are intended for general guidance only. No responsibility for the contents can be accepted.
1.) What is blind rivet - an introduction
A blind rivet consists of two parts:
a. The rivet body, also referred to as the rivet’s sleeve, and within it
b. the setting device, the mandrel (sometimes called the nail or rivet pin)
The rivet body is normally manufactured from one of three methods:
a. from wire, the most common method
b. from tube, common in longer lengths, not normally as strong as wire drawn
c. from sheet, least popular and generally the weakest option.
Blind rivets are particularly used when access to the joint is only available from one side. The rivet is placed in a pre-drilled hole and is set by pulling the mandrel head into the rivet body, expanding the body and causing it to flare against the reverse side. As the head of the mandrel reaches the face of the blind side material, the pulling force is resisted, and at a predetermined force, the mandrel will snap at the break point of the mandrel. A tight joint formed by the rivet body remains, the head of the mandrel remains encapsulated at the blind side, although variations of this are available, and the mandrel stem is ejected.
