Installation Notes

Self-drilling screws are installed using a powered drill or impact driver fitted with the appropriate hex bit or nut driver attachment. Confirm the selected screw length and thread pitch are appropriate for the material thickness before driving. Do not overdrive self-drilling screws, as excessive torque can strip the material or shear the fastener head. Follow applicable code requirements for fastener type and spacing when used in structural or code-governed assemblies.
