How Blind Rivets Work
HOW BLIND RIVETS WORK
Finally, the mandrel reaches its predetermined break-load, with the spent portion of the mandrel breaking away and being removed from the set blind 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.
The mechanical function of a blind break-mandrel rivet during installation.
Dome Head Blind Rivet
The dome head blind rivet is the most widely available and commonly used head style of blind rivets. The dome head flange offers good bearing surface and is suitable for many applications. Dome head blind rivets are available in 3/32", 1/8", 5/32", 3/16" and 1/4" diameter in all materials.
Countersunk Head - 120° Blind Rivet
The countersunk head blind rivet is used in applications requiring a flush surface. Countersunk blind rivets are available in 1/8", 5/32", and 3/16"diameter.
Blind Rivet Material Compatibility
The blind rivets selected should be compatible with the materials being joined. Dissimilar materials can cause failure due to galvanic corrosion. GESIPA blind rivets are available in the following material combinations:
Strength Requirements of Blind Rivets
The joint strength required will determine the diameter and spacing of the GESIPA blind rivet.
Material Thickness for Blind Rivets
Each GESIPA blind rivet is engineered for a specific range of material thickness for which it will be effective. This range of material or work thickness is the blind rivet’s "grip range".
Hole Size for Blind Rivets
Proper hole size is important to insure the integrity of the fastened joint. The recommended hole size and tolerances are shown in the technical data charts. Oversized holes can cause problems in blind riveted joints. A solution is to select a blind rivet which creates an oversized upset head (see Bulb-tite and Tri-fold rivets).
