Primary Selection Criteria

Head Style

Dome Head
The dome head blind rivet is the most widely used rivet, the dome head flange offers good bearing surface and is suitable for many applications. We offer dome head rivets in these diameter 3, 4, and 5 mm.

Large flange
The large flange blind rivet offers a larger bearing surface than the Dome Head and is suitable for joining compressible or brittle materials to structural members. For instance, Wood /steel, plastic/ steel.

Edge Distance

A distance of two times the rivet diameter (D) or more from the rivet center to the end of the work piece is recommended to avoid material fracture.

Material compatibility

The blind rivet selected should be compatible with the materials being joined. Dissimilar materials can cause failure due to corrosion and other reasons.
When a standard type rivet is used to set soft materials onto hard materials, fracture of the soft material should be prevented

  •  When the soft material is positioned at the secondary side, use a metal washer.
  • When it is located at the flange side, use a large flange to distribute the stress.

MPI produces blind rivets in the following materials combination.
Aluminum Rivet/ Steel Mandrel
Copper Rivets / Steel Mandrel

Aluminum Rivet/ Aluminum Mandrel
In our expansion scheme, considering to manufacture the following products
Steel Rivet/Steel Mandrel

Strength Requirement

The strength will determine the diameter and spacing of the MPI's blind rivets.
First assess the tensile and shear loads the riveted joint must withstand in service.

Actual performance will depend on component materials and thicknesses.

MPI’s blind rivets are categorized in to two group S and M

 

  • S: suitable for places where there isn’t much shear force acting upon the fastener
  • M: suitable for places where there is shear and tensile force acting upon the fastener

Joint Thickness

Having identified a rivet of the correct strength, calculate the combined thickness of the components to be joined. An allowance should be included for any intermediate layer such as a sealant and/or for any gap between materials prior to setting.
MPI's rivets are engineered and designed for specific range of materials thickness for which it will be effective. The recommended thickness range over which the body length will consistently provide a good setting are provided in the technical chart.

Hole Size

The right hole size is important to insure the integrity of the fastened joint. Oversized holes and/or  small holes can cause problems in blind riveted joints.The recommended hole size are shown in the technical data charts.

Gap Fastening

  Blind Rivets are widely used in assembling extruded sections because of the limited access and clearances involved. As shown in (A), avoid setting against unsupported internal sections, which results in poor rigidity. Select (B) to insure success.
