Industrial Quality Aluminum/Aluminum rivets are a low cost alternative to screws, bolts, or spot welding. They conform to IFI specification 114 and are quick and easy to install with hand or power tools. Both aluminum bodies and mandrels have a polished finish and are sealed to prevent discoloration. Blind Rivet Installation A blind rivet consists of two pieces that are pre-assembled: the rivet body (usually just referred to as the rivet) and inside it is the setting mandrel (commonly just called the mandrel). Installation of blind rivets is easy: (1) insert the rivet into a hole that passes through the items to be joined; (2) insert the mandrel into the special installation tool; (3) "set" the rivet by pulling on the mandrel, which creates a bulge that permanently and securely fastens the items. At a predetermined point, the exposed mandrel will break off inside the rivet. FAQ                                                             Q: Are you trading company or manufacturer ?
