Blind Rivet

Description

A blind fastener which has a self-contained mandrel which permits the formation of an upset on the blind end of the rivet and expansion of the rivet shank.  The mandrel is pulled into or against the body , breaking at or near the junction of the mandrel shank and its upset end. 

Dome Head- The dome head is slightly rounded and twice as wide as a body diameter

Large Flange Head- The large flange head has twice the under-head bearing surface of comparably sized dome head rivets.

Countersunk Head- The countersunk head is a flat on top, with a countersunk at an angle of 120°.

Applications / Advantages

Dome Head- Dome head is the most commonly specified head style because of its low profile and neat finished appearance.

Large Flange Head- Large flange rivets are preferred where extra brittle or soft materials are being assembled to a rigid surface.

Countersunk Head- The countersunk head style provides a smooth offside surface and sufficient clearance for moving parts which pass over the rivet head.

Aluminum Rivet / Aluminum Mandrel- have the lowest tensile and shear values of all break mandrel rivets.  They should be used when fastening materials with similar mechanical and physical properties.

Aluminum Rivet / Steel Mandrel- The steel mandrel gives this style rivet greater tensile and shear values than aluminum mandrel.  They should be used when fastening materials with similar mechanical and physical properties.

Steel Rivet / Steel Mandrel- The all steel design gives this style greater tensile and shear values than all varieties of aluminum rivets.  They should be used when fastening materials similar to carbon steel.

Stainless Steel Rivet / Stainless Steel Mandrel- They resist tarnishing under most conditions and offers high strength at moderately raised temperatures.  They should be used when fastening materials with mechanical and physical properties similar to stainless steel.
