blind rivet

mechanical fastener with the capability to fasten together the component parts of an assembly even though the access for its installation and setting may be limited to one side only

Note 1 to entry: It comprises a body containing a mandrel or pin which, during setting, deforms the blind rivet end. It may also expand the shank.

2.1.1

blind rivet body

blind rivet head

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

2.1.1.1.1

protruding blind rivet head

blind rivet end

extremity located at the opposite end of the shank to the head

Note 1 to entry: It may be closed, open or split.

2.1.1.4

blind rivet core

axially located hole in the body

Note 1 to entry: It may either extend through the full length of the body or only partly through it.

2.1.2

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.

2.1.3

blind head

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

2.3.1

open end

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

2.3.2

open end, extended set

2.3.3

closed end

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

2.3.4

split end

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

2.3.5

slotted shank

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

2.4.1

filled core

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

2.4.2

semi-filled core

rivet having only a short length of the mandrel retained in the body

2.4.3

hollow core

rivet having no part of the mandrel retained and where the body is hollow

2.5.1

ultimate tensile load

maximum axial tensile load the blind rivet can sustain before failure

2.5.2

ultimate shear load

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

2.5.3

rivet setting load

load applied to set the rivet

2.5.4

mandrel break load

load necessary to break a break pull mandrel after setting

2.5.5

pull-together capability

capability of a blind rivet during setting to close any gap between the components to be fastened

2.5.6

clamping force

maximum force applied to a joint by the blind rivet during setting

2.5.7

residual load

axial tensile force in the blind rivet after setting

2.5.8

mandrel push out resistance

resistance of the mandrel to being separated from the rivet body prior to setting

2.5.9

mandrel head retention capability

capability to retain the portion of mandrel remaining in the blind rivet after setting

2.5.10

sealing capability

capability of the set blind rivet to prevent the escape of gas, liquids or solids through the core and clearance hole

2.5.11

hole fill capability

extent to which lateral expansion of the shank after setting fills the clearance hole.

2.6.1.1

rivet length

l

distance, measured parallel to the axis of the blind rivet, either from the underhead face of the protruding head or from the top face of the countersunk head to the blind rivet end

2.6.1.2
