Fastener SuperStore, Inc. Blind Rivet 371911

3/16 X .12-.25 (#64) Aluminum / Steel / Closed End / Countersunk Head / Blind Rivets An aluminum blind fastener with a self-contained steel mandrel whose mandrel head is completely protected and secured within the closed end of the rivet. The head of the rivet body is countersunk at an angle of 120°. Closed-end rivets are used where the adjoining back-plate cannot be accessed but must be kept weatherproof. The installed rivet forms a tight seal preventing seepage of liquid or gas through the fastener assembly. The countersunk head style provides a smooth offside surface and sufficient clearance for moving parts which pass over the rivet head. They are preferred in many electronics applications because there is no chance of the mandrel falling into the work area on the blind side. Closed-end rivets provide greater tensile and shear strength than similar-sized open end rivets. They should be used when fastening materials with mechanical and physical properties similar to aluminum.
