How to select rivet

Blind rivet riveting strength

First determine the tensile and shear values required for the application.These are functions of total riveting strength,fastener spacing,rivet body material and rivet diameter.Then refer to the shear and tensile columns on the product then select a rivet that provides the values required.

Blind rivet joint thickness

Measure the total thickness of the materials to be joined. This determines the required grip of the rivet you select.Refer to the grip range column and select a rivet with a grip range that includes the work thickness required.Remember that insufficient rivet length will not allow proper formation of the secondary head at the back of the work.

Nature of rivets material

Both the rivet and the materials to be fastened will affect the ultimate joint strength.As a general rule,the rivet materials should have same physical and mechanical properties as the materials to be fastened,because a marked dissimilarity may cause joint failure due either to material fatigue or galvanic corrosion.

Hole size

Hole size can be important in blind riveting.Too small a hole will,of course,make rivet insertion difficult.Best practice is to follow the hole size recommendations provided.

Rivet head style

The low profile dome head rivet is appropriate for most applications.However,when soft or brittle materials are fastened to a rigid backing member,the large flange head rivet should be considered,because it offers twice the bearing surface. Where a flush surface is required,the countersunk head rivet style should be selected.
