Sealtite Eclipse Steelbinder screws are self-drilling pole barn screws designed to attach metal roof and sidewall panels on pre-engineered metal buildings. The eclipse screw features a truss head that utilizes a T-30W 6 lobe driver to create a low profile appearance on sidewall applications. Coated screws feature a tough 2.5 mils of powder coating that will not chalk or fade due to the UV inhibitor in all colored coatings. Self-drilling point penetrates steel thickness up to .210” . Undercut EPDM rubber washer provides a secure seal even when driven at an angle.
