Overview

• 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
• Steel is strong and durable but less corrosion resistant than stainless steel
• To improve its resistance to corrosion, it may receive additional finishes and coatings.
