WebbScrew clamps are designed to apply their maximum holding force in their intended use, which means tightened by hand. Using wrenches or pliers will either damage or destroy the clamp and, potentially, your workpiece. Tighten the clamp only until you feel resistance. Do not overtighten or force the clamp to close further. WebbNote: These notes have been based on W being a vertical force i.e a wieght is being lifted or lowered . As an example a 1000kg mass would result in a vertical load of 1000.g = 9810 N. . The equations are equally valid if the Force (W) is simply an axial force along the screw axis.
