Clinch Nuts & Studs

After selecting the appropriate power unit, you will need to purchase the correct head to use. Select the head based on whether your fastener is a clinch nut (female threads) or clinch stud (male threads). You will also need to determine if your application requires a serrated or smooth head. A serrated style head will better grip the clinch nut/stud during the installation process, preventing the fastener from rotating, and reducing the torque reaction on the operator. A smooth style head reduces the risk of damaging smaller fasteners, and is preferable in cosmetic applications where visible serrations left on the fastener would be undesirable.
