Specification: Material: Aluminum Color: black coated handle Rivet size: 1/8"" x 1/4""------45 pieces 1/8"" x 3/8""------40 pieces 5/32"" x 3/8""------25 pieces 5/32"" x 1/2""------25 pieces 3/ 16"" x 1/2""------25 pieces 3/16"" x 5/8""------20 pieces How to use❓: Insert the rivet assembly into the hole through the part to be connected, and use a specially designed tool to draw the mandrel to insert the rivet. This enlarges the blind end of the rivet and then the mandrel breaks. These types of blind rivets have non-locking mandrels and are sometimes avoided for critical structural joints because the mandrels may fall off due to vibration or other reasons, leaving hollow rivets with lower load-bearing capacity than solid rivets. Blind rivets are mainly used in situations where the joint can only be contacted from one side. Tips: 1.) The color may vary from different monitors, please understand. 2.)
