blind rivet body

rivet element which comprises head, shank, end and core

blind rivet head

preformed portion of the blind rivet body which is always located on the access or installation side of the joint

blind rivet shank

part extending from the underside of the head to the rivet end: Its cross section is normally circular.

blind rivet end

extremity located at the opposite end of the shank to the head: It may be closed, open or split.

blind rivet core

axially located hole in the body: It may either extend through the full length of the body or only partly through it.

mandrel

component, usually with a break area, pre-assembled in the blind rivet body

Note 1 to entry: It has an upset head and its shank may be plain or grooved.

Note 2 to entry: Pulling or driving the mandrel sets the blind rivet by deforming the end of the blind rivet body into the blind head.

blind head

upset portion of the blind rivet body, remote from the head, formed by the mandrel during setting

pull mandrel

after insertion of the blind rivet through the components to be fastened, mandrel pulled axially with its head upsetting the end to form the blind head

pull through mandrel

after setting the body, mandrel pulled completely through the body resulting in a hollow rivet

break pull mandrel

after setting the body, mandrel breaking at or near the junction of the mandrel head and its shank, the head and a small portion of the shank of which are retained in the rivet body

break head mandrel

after setting the body, mandrel breaking at the junction of the mandrel head and its shank, at which point both shank and head are ejected resulting in a hollow rivet

blind rivets shanks open end

rivet body, hollow throughout its length and able to use any type of mandrel

blind rivets shanks open end, extended set

open end rivet body with characteristics which enable it to join component parts over a broad range of thicknesses

blind rivets closed end

rivet body, the end of which is closed and remains closed after setting

blind rivets split end

rivet body, the end of which is split axially into two or more segments

blind rivets slotted shank

rivet body, the shank of which has axial slots between the underside of the head and the end

blind rivets filled core

<after setting of the rivet> rivet, the mandrel of which is retained in the body having its end generally flush with the top of the blind rivet head

blind rivets semi-filled core

<after setting of the rivet> rivet having only a short length of the mandrel retained in the body

blind rivets hollow core

<after setting of the rivet> rivet having no part of the mandrel retained and where the body is hollow

blind rivets ultimate tensile load

maximum axial tensile load the blind rivet can sustain before failure

blind rivets ultimate shear load

maximum single shear load the blind rivet can sustain prior to failure

blind rivets mandrel break load

load necessary to break a break pull mandrel after setting
