Square/Allen Drive Working Torque

Размер привода The square or hex drive of each drive is limited in its maximum output by its material and its engagement area. Since Atlas Copco uses a specially suited alloy-steel for its drive members, the following maximum torque output can be achieved without drive failure, provided the reaction member abuts close to the same plane as the nut to be turned.

If the reaction arm cannot abut on the same plane as the nut to be turned, less torque should be applied, as the additional side load has to be taken into consideration. When toque requirements are close in excess of the values listed above, use RT's/-9/ Sockets Hex-Drive with replaceable Hex Insert Bits.

RT series is available with square drive (standard) or option hexagonal/Allen drive. The table below reviews ideal working range for the respective drives.
