Overview

• Aluminum has a high strength-to-weight ratio and is wear resistant, nonmagnetic and conductive
• It is easier to form and machine than steel and is naturally noncorrosive
• Expander head types expand after installing a screw or bolt
• They have long, smooth shanks and thin, flat heads
• Standard rivet nuts have two open ends and a head with a narrow flange
• The open ends allow for the use of long screws and bolts, while the narrow flange prevents pull-through.
