DEFINITIONS 3.1 Free Torque The torque value expressed in newton meters (pound inches) when the clamp is tightened four complete revolutions of the screw or nut, while in the free state. This value does not include any break-away effects due to staking or passage of the band ends beyond the screw head. 3.2 Durability Torque The maximum torque value applied to a clamp without evidence of deformation or excessive wear when tightened once over a steel mandrel. 3.3 Installation Torque The recommended torque for installation of the clamp. This is generally expressed in terms of 50% to 75% of the rated “ Durability Torque” for specific clamps. Installation Torque is sometimes referred to as Application Torque. 3.4 Ultimate Torque The torque value at which the clamp develops deformation to a degree that it cannot be reused or no longer achieves its intended use. 4. CLASSIFICATION For ease of handling the various clamp designs and modifications thereof; clamps have been grouped by their basic design and functional characteristics: 4.1 Group #1 (Types “ A,” “ AHH,” “ B,” “ D,” “ C,” “ F,” “ FEO,” “ FE,” “ HD,” “ I,” “ M,” “ MX,” “ TB,” “ SSC,” and “ G” Clamps which require torquing a screw or nut for installation. 4.1.1 “ A” and “ AHH” Dual body wires utilizing a machine screw with trunnion nut for the tightening mechanism. Screw position tangential to the diameter. See Figure 1 and Tables 1A and 1B. 4.1.2 “ B” and “ D” Flat band body stock utilizing a machine screw and square nut for the tightening mechanism. Screw position tangential to the diameter. See Figures 2, 3A, and 3B and Tables 2 and 3A, and 3B. 4.1.3 “ C” Flat band body stock utilizing a bridge structure to position the machine screw and nut tightening mechanism perpendicular to the diameter. See Figure 4 and Tables 4A and 4B. 4.1.4 “ F,” “ FEO,” “ FE,” “ HD,” “ I,” “ M,” and “ MX” A tangential worm drive screw engaging either pierced through slots or embossed threads. Those using pierced through slots are also available in extended band versions to protect soft hose compounds. See Figures 5 to 11 and Tables 5 to 14. NOTE: “ FE” means type “ F,” embossed slots; “ FEO” means type “ F,” embossed slots with screw offset from centerline of the band.
