Fasteners are designed to withstand a varied range of types of loading. Each panel or structural system has its own specific fastener loading requirements. Care must be taken to ensure that the appropriate loading requirements for each application are considered. Typical structural performance criteria that influence fastener design include: Ultimate Tension Strength Ultimate Torsion Strength Ultimate Shear Strength Pull-out Performance Pull-over Performance Ultimate Tension Strength The point at which a fastener fails under a load exerted in two direct opposite directions. Typical ultimate tension strengths of each fastener type are provided on the fastener information pages. Ultimate Torsion Strength The point at which a fastener fails under a twisting load exerted on the head during installation in a torsional direction. Typical ultimate torsion strengths of each fastener type are provided on the fastener information pages. Ultimate Shear Strength The point at which a fastener fails under a load exerted in offset opposing directions, usually upon the shank of the fastener. Typical ultimate shear strengths of each fastener type are provided on the fastener information pages. Pull-out Performance The ability of a fastener's threaded connection to remain intact and resist tensile loads. Self-tapping fasteners require that a pilot hole be drilled prior to installation. The pullout resistance will be directly related to the pilot hole diameter. Self-drilling fasteners have been developed, and are available, for most steel construction applications, to a metal thickness of 1/2". This type of fastener is manufactured with its own integral drill point, which is engineered to drill the optimum hole size to facilitate efficient thread forming in the metal structure, resulting in optimized pullout values. Pull-over Performance The ability of a fastener to resist the pulling of the fastened sheet material over the head of the fastener due to gravity, wind, or other load. The resistance to pullover failure is related to the strength and diameter of the fastener washer and the strength and thickness of the metal panel. Learn more about Weather Gard® Products.
