Innovative Tapered Compression Point technology
Atlas self-sealing FlatTop drilling fasteners are manufactured using an innovative tapered compression point process (TCP). Combined under-cut hex washer heads with EPDM cut-tubular sealing washers, Atlas FlatTop fasteners are a superior and cost-effective alternative to standard fasteners with metal back washers. One-piece design eliminates damage to painted washer surface and eliminates dissimilar metal washer materials. FlatTop self-sealing fasteners come in a full range of sizes and drives and are available with corrosion inhibiting OxySeal II coating for extended life.
