The basic difference between Perforated and Serrated clamps is, Perforated clamps have pierced teeth on the band of the clamp which engages with the screw, whereas in case of Serrated clamps, the teeth on band are formed which engages with the screw to provide the necessary clamping force.
In case of perforated clamps there is a possibility of hose biting on a soft hoses due to pierced teeth. To avoid this liner can be orovided to protect soft hose in the specific application. Application torque in perforated clamps would be higher than serrated clamps.
In serrated clamps hose biting issue doesn’t arise due to rolled edges of the threads and smooth underside. Also, the serrated clamp’s residual torque is higher by almost 30% to 50% than perforated clamp.
