Screw Torque and Force Capacity

Please note: The values below are taken from a controlled environment, and are not specific to a particular screw type - different fasteners will have different attributes which can affect the values given within this table. Many external factors such as temperature and the housing material can cause significant variation to breaking torque, meaning that Accu cannot guarantee the values below, and they should be used as a guide only.
