The Standard
Blind Break-Mandrel Rivet is comprised of two components,
a rivet body and mandrel. The rivet is first placed into an
installation tool, and is then inserted into the application
or vice versa. Activating the tool pulls the rivet's mandrel
drawing the mandrel head into the blind-end of the rivet body.
This action forms an upset head on the rivet body and securely
clamps the application materials together.
|
|
|
Finally the mandrel reaches its predetermined
break- load, with the spent portion of the mandrel breaking away and
being removed from the set rivet. Fast, easy-to-use blind rivets offer
speed of assembly, consistent mechanical performance and excellent
installed appearance, making blind riveting a reliable and economical
assembly method. |

Guide
to select a rivet |
|
|
Strength
Select a Rivet based on strength required, corrosion resistance and materials
to be joined. Rivet material
The rivet material is decided on sheet materials to be joined
Aluminium : Medium strength generally used with aluminium
sheets
All steel : this is used to join steel with steel sheets
/ plates.
All Stainless Steel : This is used to join stainless steel
sheets or wherever corrosion resistance is required. |
|
Rivet head
Rivet will bear on the sheet >> Dome Head. |
|
Application requires flush surface
>> Countersunk Head. |
|
|
|
Rivet diameters
Dia selection again depends in strength requirements. Rivet
length
This is decided on Grip rage. (see datasheet)
Grip range
Total thickness of material to be joined is called grip Range.
This is an important factor as wrong Rivet length decided might effect
the efficiency of joint. Case study
A stainless steel fabrication calls for a joint strength of a
400 N - Shear and 700 N- Tensile, sheet thickness to be joined are
2 mm and 1 mm, Environment - Corrosive,
Preferred diameter is 3.2 mm (see datasheet).
Rivet to be used is stainless steel, Dome head,
rivet size is 3.2 x 6.85 mm |
|
|
|
|
Note : Always use correct and recommended
drill size for Rivet hole.
Recommended riveting tool - Pneumatic tool. Hand tool can also be used. |
|
Size range
General sizes 3.2 ,4.0, 4.8 dia in mm. Also available 2.4 and 6.4
diameter rivets
( Lengths available to join grip range from 1.00 mm to 22 mm) |
